| concur with what was said so far. Engines are designed for a certain octane. One could use higher octane, but never lower octane, than recommended. But it’s a waste of money to use higher octane unless necessary. | |||||

| Is she using a low octane gas. I live in the east where we have 87-89and 93 octane. We went to Amarillo for a conference. I filled the car with the lowest octane which was 86. The car ran differently. There the octane is 86-88 and 90. The next fill I put 88 and it ran fine. | |||||

| If your vehicle takes 87, there's no harm in pumping higher octane. Higher octane typically applies to turbo cars to reduce the amount of engine knock unless the user manual REQUIRES higher octane. You should be fine pumping higher octan but its just a waste of money if you're not driving a turbo-ed car or vehicles that require higher octane. | |||||

| some time ago and I don't drink that much kool-aid now, you would get a small packet of cherry kool-aid and add your own sugar and water. Add more sugar for more sweetness. This may change the taste of the cherry kool-aid but the cherry flavor is still the same (almost) concentration. So appearances are deceiving in gasoline also. 87 octane in some states is 85 octane with ethanol added to average out to 87 octane. So, this type of averaging is completely elementary. The gas is still 85 octane. You dont want 85 otane gas in your car. | |||||
| Answer to: High Octane Gas and Injector Cleaner as part of routine maintenance | 29Relevance | 5 years ago | alban123 | Submit Your Question HERE | |
| octane is just the measurement of how much pressure the fuel can take before it self ignites. In higher compression engines that are in fancier cars, you need higher octane fuels because if you don´t you will get something called engine knock. That is where the air-fuel mixture ignites before it is supposed to. If your car only requires 87 octane, that means that your engine does not have extremely high compression, so there is no benefit of using 91 or higher. See what the manufacturer recommends for your model and use that. And I believe that fuel additives are good to use every once in a while. Needless to say, don´t waste your money by pouring them in at every fill up. Thats my 2cents... | |||||

| What method is used to calculate octane rating in Japan? In the U.S. it's the average of the RON (Research octane Number) plus MON (Motor octane Number), frequently written as (R+M)/2. The octane ratings in other countries cannot be assumed to match those in the United States. You may have some other problem, like carbon buildup increasing compression or ignition too far advanced. | |||||
| Answer to: Which gasoline should I use | 27Relevance | 4 years ago | Neferati | Submit Your Question HERE | |
| I always use high octane petrol with additives, despite being the most expensive one. Higher octane will cause a bigger explosion, reduce/avoid knocking if there's any, and the additives keep the fuel lines, spark plugs and cylinders clean within. It's also fully compatible with cars since the 80's/90's as far as I am aware. Also, car brands do their performance testing with the best fuel possible, I remember a long time ago in the BMW European website publishing their benchmarks, and mentioning which kind of fuel they used at the footer (which was always the higher octane one). I also believe premium fuel allows you to drive further, at the same speed/effort. For instances, people with motorcycles feel a very significant increase in acceleration speed, when they switch to high octane premium fuel, because motorcycles are lighter and it's possible to actually notice such a difference. About the ethanol part, I personally don't know. | |||||
| Answer to: Will converting a Petrol Engine to LPG ruin my car ? | 27Relevance | 4 years ago | DontKnowler | Submit Your Question HERE | |
| LPG will actually ruin your engine. The gas combustion process is so much different from petrol combustion, that very few petroleum engines can survive it long-term. I would need to write a multi-page paper for explaining the reasons properly, but using gas instead of normal petrol is like using an extremely high-octane fuel (like 105+ octane): if your engine is not designed for it (and it is not), your engine - and first of all the engine head - will become an expendable spare part. LPG kit designers and installers know it (talked to them personally), but hate telling it to their customers. And the octane is not the only thing about LPG which can be lethal for an engine, unfortunately. If you really want a car that can use LPG and last, buy one from the Netherlands, which had been converted to LPG at the factory. P.S. The funny thing is that petroleum engines which survive LPG best are the ones their owners would almost never think about converting to LPG. They are high-power turbocharged engines of all sorts of "sporty" cars like Audi S-line etc. Those are designed to consume "racing-grade" high-octane gas and take beatings, but their owners bought them for their power and would hardly want to live with the power output reduction any gas conversion inevitably brings. And - again - it is not that those engines would not suffer from LPG usage - it is that those would suffer less than other engines. And the petroleum engines that are least suitable for running on LPG are the ones converted to LPG most often - those are high-volume atmospheric engines like all sorts of 4-5-6l V8 etc. Those are known gas hogs, and I can understand their owners´ willingness to do anything to save money on fuel. And upon LPG conversion their fuel economy often - and soon - reaches its theoretical maximum - since ruined engines do not consume fuel at all, ha-ha. | |||||
| Answer to: My Lexus Is250 AWD says I should put 91 premium gas, can I put 87 and if i do would that ruin the car? | 27Relevance | 5 years ago | Doc | Submit Your Question HERE | |
| If the manufacturer specifies 91 octane, you better use 91 octane. If you want to use a lower octane gas, you'd probably have to figure out a way to retard the ignition timing so the engine won't ping (detonate). With the older cars, we just rotated the distributor back so a timing light showed about 2 degrees less in advance. Newer, electronically controlled vehicles will most likely have to be re-programmed to handle the lower octane fuel. | |||||

I had one mechanic tell me I can get away with using regular 85?octane gas and another telling me that I must use minimum 91 octane or I risk ruining my engine/s. What advice could you offer? thanks Kalman Strauss | |||||
