What octane-level gas should I use? Is there any benefit to paying more for "premium" fuel?

Answer 1

You should use the octane-level fuel that is recommended for your engine. Your car's user's manual will tell you this.

The high octane gas requires higher temperatures to ignite. This allows more time for higher compression and more energy to be created. If you don't run high octane gas in an engine designed for high octane gas (high compression engine), you will ignite the low octane gas too quickly which can seriously damage your engine.

If your engine is rated for lower octane gas (87 octane), and you use high octane gas in it, then you will not reach temperatures high enough to efficiently burn the high octane gas. You will waste the expensive gas and possibly dirty your engine by not cleanly burning the high octane gas.

Answer 2

really dont know where some people get their info from but yes there are benefits to higher octane gas all cars will burn high octane fuel it will burn hotter and keep the engine cleaner from carbon build up it will perform better and help the engine to last longer anyone that says it dont make a difference has never rebuilt a motor that has used it and seen the difference in them it is well worth the money if you want to cut down on the cost of repairs and eddi gordo you are way off on your info

Answer 3

The higher the octane rating, the less explosive the fuel. Use what your car's manual requires. Unless you are running a real hog of a street rod engine, you are probably wasting money buying premium fuel.

Answer 4

It does depend upon the vehicle, engine. If the manufacturer tells you that you need a higher octane, then use it. If not, then use a regular octane. The manufacturer has over 100 years of experience and a large staff of engineers and scientists. They know what they are talking about. If the information they give is incorrect, it is a lie and not a mistake....unless it is a typo.

Answer 5

You should use the octane rating that your owner's manual calls for. The only time using higher octane fuel is justified is if your engine starts pinging.

Answer 6

Use the lowest level octane you can find. If your engine makes funny pinging noises, then use a higher octane.

If you drive a $45,000 monster gas hog with a high-compression engine, then you may need higher octane gas.

Answer 7

Only use premium fuel if your car requires it, other than that you are wasting your money, there are no benefits to premium fuel in a regular engine.

Answer 8

there is no real benefit to using premium gas, unless it is stated in your owners manual that you have to use premium gasoline. The only time i use premium is right after I pressure clean my fuel injectors.

Answer 9

there really are no benefits to it,,unless you just want to pay more for gas,,i own a repair shop,,and have tried them all,,i cant find any running difference in them,,nor did i save any money at all,,i wound up going back to the regular unleaded,,and i do as good on it as anything else,,you could try It,,but i seriously don't think it would help ,much,,good luck,,hope this helps.

Answer 10

regular gas actually burns cleaner in a combustion chamber.... I had someone tell me that regular.. mid grade.. and premium are actually the same fuel but the mid grade and premium just have more additives...anyone??
