Is XP95 Ethanol Free? The Myth Every BS4 Owner Needs to Stop Believing
XP95 is not ethanol free. It contains 20 percent ethanol, the same as standard petrol. This has been confirmed by an RTI filed with Indian Oil Corporation, independently verified by a laboratory gas chromatography test conducted by Autocar India, and corroborated by multiple Right to Information replies across cities. If you have been paying the XP95 premium believing it protects your BS4 or older vehicle from ethanol-related damage, you have been paying for additives while receiving identical ethanol exposure. This article presents the evidence, explains why the myth persists, and tells you what actually works. Table of ContentsIs XP95 Ethanol Free? The Evidence, RTI Replies and a Lab Test Why the Myth Persists What XP95 Actually Is What About Speed 95, Power 95, and Shell V-Power? What Should BS4 Owners Do Instead? The Only Ethanol-Free Option at Indian Pumps SourcesIs XP95 Ethanol Free? No. XP95 is E20 petrol. It contains 20 percent ethanol by volume, the same as standard petrol at every other pump in India. There is no reduced-ethanol or ethanol-free option available in the XP95 grade or any other sub-100-octane premium grade at Indian retail pumps. This is not ambiguous. It is not a matter of interpretation or regional variation. It is confirmed by the oil company itself through an official government transparency mechanism. The Evidence, RTI Replies and a Lab Test RTI Reply, IOCL, July 2025: A Right to Information application filed with Indian Oil Corporation in June 2025 asked two direct questions: what is the ethanol percentage in XP95 petrol sold in Kolkata, and what is the ethanol percentage in standard Motor Spirit sold in Kolkata. The reply, issued by IOCL's Public Information Officer on 3 July 2025, gave the same answer to both questions: 20 percent. XP95 and standard petrol contain identical ethanol content. A separate RTI filed earlier confirmed the same finding across Delhi outlets. IOCL's pan-India response has been consistent: XP95 is blended with up to 20 percent ethanol across India, depending on availability of ethanol at supply locations. The upper limit is 20 percent. There is no minimum-ethanol or ethanol-free XP95 variant. Gas Chromatography Lab Test, Autocar India, September 2025: Autocar India obtained fuel samples of standard petrol and XP95 from retail pumps and sent them for independent gas chromatography testing, the only scientifically reliable method for measuring ethanol content in fuel. The results were unambiguous. Standard petrol tested at 20.86 percent ethanol, slightly above the stated 20 percent, within blending tolerances. XP95 tested at 19.88 percent ethanol. Both grades are E20 fuels by any reasonable definition. Autocar India also tested XP100 and Power 100 from the 100-octane segment. Both returned zero percent ethanol, confirming that E0 status is genuine and exclusive to the 100-octane grades. The chromatography test is important because it eliminates the ambiguity created by water separation tests, a popular DIY method used by enthusiasts to detect ethanol in fuel. Water separation tests are unreliable. Fuel additives including MTBE can produce false positives, suggesting ethanol-free fuel when ethanol is present, or vice versa. The GC test is definitive. Why the Myth Persists Several factors reinforce the XP95-is-ethanol-free belief, none of them accurate. The price premium signals quality: XP95 costs more than standard petrol. Consumers reasonably infer that a premium price means a purer or higher-quality product. In terms of performance additives, that is partially true, XP95 contains a detergent and deposit-control additive package that standard petrol does not. But those additives have no bearing on ethanol content. The price premium reflects additive cost, not ethanol reduction. The name "XP95" sounds performance-oriented: "XP" implies extra performance. "95" appears to reference the octane rating. Neither part of the name says anything about ethanol content, but the branding positions the fuel as a cut above standard, leading buyers to assume it is better in every dimension. Oil companies initially gave contradictory answers: When vehicle owners contacted IOCL, BPCL, and HPCL on social media in 2025 asking about ethanol content in premium grades, some responses incorrectly stated that premium fuels contained E10 or E15. Those responses were inaccurate. The RTI mechanism and independent testing have since provided authoritative confirmation that all sub-100-octane grades are E20. Water separation tests produced confusing results: Home ethanol testing using the water separation method became popular on forums and YouTube in 2025. These tests frequently produced inconsistent results, sometimes suggesting low or zero ethanol in XP95, sometimes suggesting high ethanol. The inconsistency led some owners to conclude that XP95 had variable or lower ethanol content. The GC test confirmed this interpretation was wrong. The water separation method is not reliable for these fuels. What XP95 Actually Is XP95 is standard E20 petrol with a performance additive package. The additives serve real purposes: Detergent additives help prevent carbon deposits on fuel injectors and intake valves, particularly relevant for fuel-injected engines that accumulate deposits over time. Deposit-control chemistry helps maintain fuel system cleanliness in engines that see varied fuel quality or extended service intervals. The 95 RON octane rating is not meaningfully higher than standard E20 petrol. Before the E20 mandate, standard petrol in India had a RON of approximately 91. Blending 20 percent ethanol raises the octane rating to approximately 95 RON. Standard E20 petrol now meets the 95 RON minimum under BIS IS 2796. XP95 and standard petrol are both 95 RON fuels. The octane gap that once existed between them has been eliminated by the ethanol mandate itself. In practical terms: XP95 offers cleaner injectors and intake valves compared to standard petrol in fuel-injected engines. It offers no ethanol reduction, no corrosion protection from ethanol, and no mileage improvement beyond the small cleaning benefit for deposit-laden injectors. What About Speed 95, Power 95, and Shell V-Power? The same answer applies to all of them. Bharat Petroleum's Speed 97 contains 20 percent ethanol. BPCL confirmed this directly. Hindustan Petroleum's Power 95 contains 20 percent ethanol. Shell V-Power, sold at select Shell outlets in India, contains 20 percent ethanol. All premium petrol grades below 100 octane in India are E20. CarDekho independently confirmed this through oil company responses: there is no intermediate blending in India's retail fuel market. The choice is binary, standard E20 petrol, premium E20 petrol with additives, or 100-octane E0 petrol. There is no reduced-ethanol middle ground at any price point. What Should BS4 Owners Do Instead? The underlying concern driving XP95 purchases among older vehicle owners is legitimate: ethanol damages fuel system components in BS3 and BS4 vehicles not designed for it. That concern is real and well-founded. The solution, however, is not premium petrol. It is targeted maintenance. Replace nitrile rubber fuel hoses with Viton FKM equivalents. Nitrile rubber degrades under sustained ethanol exposure. Viton, also called FKM fluoroelastomer, is ethanol-resistant and is the appropriate replacement material. This is a one-time intervention that eliminates the primary mechanical risk. The relevant article on this site covers the replacement process in detail. Inspect and replace carburettor bowl gaskets at service intervals. The carburettor bowl gasket in a carburetted BS4 bike is typically nitrile rubber. It is inexpensive and accessible. At your next service, ask the mechanic to check its condition and replace it if there is any sign of swelling or degradation. Rejett the carburettor if misfiring. Carburetted engines running lean on E20, because ethanol has lower energy density than petrol, may exhibit rough idle, misfiring under load, or hesitation at partial throttle. Rejetting the carburettor corrects the air-fuel ratio for E20. This is a mechanic task, not DIY. It does not involve the ECU and applies only to carburetted engines. Establish a mileage baseline. Measure your kmpl over three full tanks using a consistent method. Knowing your actual mileage gives you a reference point. A drop of more than 10 to 15 percent from your pre-E20 baseline suggests a fuel system issue worth investigating, not simply the expected mileage reduction from ethanol. None of these steps involve premium petrol. The additive package in XP95 does not prevent ethanol-related seal degradation, does not reduce moisture absorption, and does not compensate for lean running in carburettors. The Only Ethanol-Free Option at Indian Pumps If you genuinely need ethanol-free petrol, for a vintage motorcycle, for long-term vehicle storage, or for a superbike with a 100-RON engine requirement, the options are XP100 from IOCL, Speed 100 from BPCL, and Power 100 from HPCL. All three are 100-octane, E0 fuel, confirmed ethanol-free by independent testing and RTI. They are available at select pumps in major cities and priced at approximately Rs 149 to 160 per litre. They are not practical for daily commuting on cost grounds. For daily use in a BS4 bike, targeted maintenance is the answer. For long-term storage or a vehicle that genuinely requires ethanol-free fuel, XP100 and its equivalents are the correct choice. XP95 is neither. It is E20 with additives. Use it for cleaner injectors if that matters to you. Do not use it as a substitute for ethanol-free petrol, because it is not one.

What Is E0 Petrol in India, XP100, Speed 100 and Power 100 Explained
Every standard petrol grade at every pump in India is now E20 — blended with 20 percent ethanol. XP95, Speed 95, Shell V-Power, Power 95, Speed 97, all of them contain ethanol. There is no ethanol-free option in the standard or premium segments. But there is one category that remains E0: 100-octane petrol. XP100 from Indian Oil, Speed 100 from Bharat Petroleum, and Power 100 from Hindustan Petroleum are the only grades of petrol available at Indian retail pumps that contain zero percent ethanol. This article explains exactly what they are, where to find them, what they cost, and, critically, who actually needs them and who does not. Table of ContentsWhat E0 Petrol Actually Means The Three E0 Options in India Why Only 100-Octane Petrol Remains Ethanol-Free Where to Find E0 Petrol and What It Costs Who Should Use E0 Petrol Who Should Not Use E0 Petrol The XP95 Myth, and Why It Keeps Spreading SourcesWhat E0 Petrol Actually Means E0 is simply petrol with zero percent ethanol content. Pure petrol, refined from crude oil, with no alcohol blended in. Before India's ethanol blending programme began in earnest, all petrol was effectively E0. Today, E0 at a retail pump is the exception, not the rule, and it comes at a significant price premium. The E in E0, E10, E20, E85 refers to the percentage of ethanol in the fuel blend by volume. E0 is 100 percent petrol. E20 is 80 percent petrol and 20 percent ethanol. The number is not an octane rating — it is an ethanol content label. This distinction matters because many vehicle owners conflate ethanol content with fuel quality, assuming that premium-grade petrol must have less ethanol. That assumption is wrong, and it has led to a widespread misconception that is actively causing problems for older vehicle owners. E0 petrol has a higher energy content per litre than any ethanol blend. Ethanol contains roughly 34 percent less energy per litre than pure petrol. A litre of E0 delivers more potential energy to your engine than a litre of E20. This is why mileage on E0 is always higher than mileage on E20 in the same vehicle, regardless of the octane rating. The Three E0 Options in India XP100, Indian Oil Corporation (IOCL): Launched in December 2020, XP100 was India's first commercially available 100-octane petrol. It carries a Research Octane Number of 100 and contains zero percent ethanol. IOCL confirmed via a Right to Information reply that XP100 does not have ethanol blending, making it the most authoritatively documented E0 option currently available. XP100 is available at select IOCL pumps across major cities. Current pricing is approximately Rs 149 to 160 per litre depending on city and state taxes. Speed 100, Bharat Petroleum (BPCL): BPCL's 100-octane offering, available at select pumps across eight cities as of early 2026. Zero percent ethanol, 100 RON. Priced at approximately Rs 151 per litre. The fuel has been independently tested and confirmed ethanol-free. BPCL's own response on social media confirmed that Speed 97 contains E20, while Speed 100 remains E0, the distinction between the two grades is not just octane, it is ethanol content. Power 100, Hindustan Petroleum (HPCL): HPCL's 100-octane, ethanol-free grade. Available at select HPCL outlets. Pricing consistent with XP100 and Speed 100 at approximately Rs 160 per litre. Same fuel specification as the other two — 100 RON, E0. All three are functionally equivalent in their ethanol-free status. The minor differences in formulation, detergent additives, lubricity improvers, may vary by brand but the core specification is identical: 100 RON, zero ethanol. Why Only 100-Octane Petrol Remains Ethanol-Free This is the question most vehicle owners do not think to ask, and the answer explains the entire landscape. Ethanol blending raises the octane rating of petrol. Pure petrol without additives typically has a Research Octane Number of around 88 to 91. Blending in 20 percent ethanol raises that to approximately 95 RON, which is why all standard E20 petrol in India now meets the minimum 95 RON specification under BIS IS 2796. For premium grades like XP95, Speed 95, Speed 97, and Shell V-Power, the octane boost from ethanol actually helps meet their octane targets without additional refining costs. There is no technical barrier to blending ethanol into these grades, and no commercial incentive for the oil marketing companies to keep them ethanol-free. For 100-octane petrol, the situation is different. Achieving a genuine 100 RON requires either high-quality base refining, specific performance additives, or both. Blending ethanol at E20 levels into a 100-octane base would raise the RON further, creating a fuel above 100, not a problem in itself, but it would change the product specification and require re-testing and re-certification. More practically, the target market for 100-octane petrol is high-performance vehicles and superbikes whose owners have heightened sensitivity to fuel quality. Introducing ethanol into this grade may likely reduce demand. The oil marketing companies have chosen to keep 100-octane as E0. This is not a regulatory requirement. There is no BIS standard mandating that 100-octane petrol must be ethanol-free. It is a commercial and technical decision by IOCL, BPCL, and HPCL. In theory, E0 100-octane fuel could be withdrawn or reformulated at any point. Where to Find E0 Petrol and What It Costs E0 petrol is available in major cities only. It is not at every pump, it is at select high-traffic outlets and those near premium vehicle dealerships and motorsport venues. For XP100, IOCL has outlets in Delhi, Gurugram, Noida, Agra, Jaipur, Chandigarh, Ludhiana, Mumbai, Pune, Ahmedabad, Chennai, Bengaluru, Hyderabad, Kolkata, and Bhubaneswar among others. To find the nearest XP100 pump, search the IOCL fuel station locator on the IndianOil website and filter by fuel type. For Speed 100, BPCL outlets are currently in eight cities. For Power 100, check the HPCL pump locator. On cost: at approximately Rs 150 to 160 per litre versus Rs 100 to 110 for standard E20 petrol in most cities, E0 petrol carries a Rs 40 to 60 per litre premium. On a 15-litre tank fill, that is Rs 600 to 900 extra per tankful. For daily commuting on a 150cc to 250cc bike doing 40 to 50 kmpl, that translates to approximately Rs 2,500 to 4,000 extra per month in fuel costs. For a 350cc to 500cc bike covering 25 to 35 kmpl, the monthly premium is Rs 1,500 to 2,500. The E0 Fuel Finder tool on this site is being developed to show verified E0 pump locations near you, initially covering Maharashtra with expansion planned. Who Should Use E0 Petrol E0 petrol is appropriate and practically justified for three categories of vehicle and use case. Long-term vehicle storage: This is the most unambiguous use case for E0. When a vehicle is stored for more than two weeks, during an extended trip, monsoon storage for a vintage bike, or simply a vehicle used only on weekends, E0 petrol eliminates the risk of phase separation. Ethanol in E20 absorbs atmospheric moisture during storage. If enough moisture accumulates, the ethanol-water mixture can separate from the petrol and settle at the bottom of the tank as a layer of dilute alcohol. This layer does not combust cleanly and can cause starting difficulty, rough running, and accelerated corrosion of the fuel tank interior. Filling with E0 before long-term storage prevents this entirely. Vintage and classic motorcycles with no retrofit available: Pre-BS3 bikes, Royal Enfield bullets from the 1980s and 1990s, Yezdi, Rajdoot, older Jawas, have fuel systems that were designed for pure petrol. Viton hose upgrades may not be available for all models, and carburettor rejetting alone does not address corrosion risk. For these vehicles, E0 petrol on a full-time basis is the most conservative approach to fuel system preservation. The price premium is justified by the cost and difficulty of replacing irreplaceable parts. High-performance superbikes with 100-RON engine requirements: Some superbikes, primarily imported litre-class motorcycles, have ECUs and compression ratios tuned for 100 RON fuel. Using lower-octane petrol in these engines can cause knock under high loads. XP100, Speed 100, and Power 100 are the correct fuel grade for these vehicles. The ethanol-free aspect is a secondary benefit; the primary reason to use them is the octane requirement. Who Should Not Use E0 Petrol This is the section that most people need to read most carefully. BS4 and BS6 commuter bikes and standard motorcycles: A standard BS4 Bajaj Pulsar, TVS Apache, or Yamaha FZ running on E0 petrol may not experience any performance improvement. These engines are not tuned for 100 RON, their compression ratios and ignition timing are calibrated for 91 to 95 RON fuel. Running 100 RON in a 91-RON engine does not produce more power, better mileage, or reduced wear. The only guaranteed outcome is a significantly higher fuel bill. The mileage improvement from E0 versus E20 in a standard bike is real, approximately 5 to 8 percent in a BS4 model, because E0 has higher energy density. But at Rs 50 to 60 extra per litre, that mileage recovery costs far more than the mileage lost. The arithmetic does not work for daily use. BS4 owners seeking to protect their fuel system from ethanol damage: This is the most important misconception to address. Some BS4 owners have concluded that filling with XP100 on every tankful will protect their fuel system from ethanol damage. This logic is correct in its premise — E0 eliminates ethanol exposure. But the solution is disproportionate to the problem. The correct response to ethanol-related fuel system concerns in a BS4 bike is targeted maintenance: replacing nitrile rubber hoses with Viton FKM equivalents, inspecting and replacing carburettor gaskets, and cleaning the fuel system at appropriate intervals. These interventions cost a fraction of the ongoing E0 fuel premium and address the actual failure modes directly. BS6 Phase 2 vehicles: These are factory E20-compliant. There is no fuel system risk from E20 in a BS6 Phase 2 vehicle. Using E0 petrol provides no benefit beyond the marginal energy density improvement, at a cost that makes no financial sense for daily use. The XP95 Myth, and Why It Keeps Spreading A separate article on this site addresses the XP95 misconception in full detail. The short version: XP95 contains 20 percent ethanol. It is E20. It is not ethanol-free, it is not lower-ethanol than standard petrol, and filling with XP95 instead of standard petrol provides no protection against ethanol-related fuel system damage in older vehicles. The misconception persists because the name "XP95" sounds premium, because it costs more than standard petrol, and because people reasonably assume that a more expensive fuel must be better in every dimension — including ethanol content. None of these assumptions are correct. IOCL confirmed via Right to Information that XP95 is blended with up to 20 percent ethanol pan India, the same as standard petrol. The only meaningful difference between XP95 and standard E20 petrol is the additive package, detergent and deposit-control additives that may help keep fuel injectors and intake valves cleaner. On ethanol content, they are identical. If you have been filling your BS4 or older vehicle with XP95 believing it to be ethanol-free, you have been paying a premium for additives while getting the same ethanol exposure as standard petrol. Switch to XP100 if you need genuine E0 petrol for storage or a vintage vehicle. If you are using a standard commuter or mid-range motorcycle daily, the maintenance approach is more cost-effective than any fuel premium.
