If a car has been given a certain type of gas for a long time would it hurt to start giving it different type of gas?

It would only hurt if the car required 89 octane or 92 octane and you went to a lesser octane. Those cars are engineered to run on a higher octane. A car engineered for the lower 87 octane might actually see some performance improvement by going to a higher octane once or twice, because the higher octane will help to clean the injectors a "little". Not much though. Over all there is no real significance to using the higher octane. The higher the octane level, the "richer" or "heavier" the fuel is. So if the car is not manufactured for the higher octane, you will eventually cause carbon build up at a faster rate than normal.


How does octane percent affect a car?

octane is how volatile the gas is the higher the octane the bigger the boom and cleaner it burns


Do you get better gas mileage by car if you use higher octane gas?

Yes, higher octane gas does give higher gas mileage for your car. However, the increase in gas mileage may not as great as the increase in the price of the higher octane gas.


Octane has a higher boiling point than pentane because .?

Octane has a higher boiling point than pentane because octane has a larger number of carbon atoms than propane


What kind of gas to use in 94 Chevy silverado 5.7 engine?

Regular Unleaded 87 octane. The use of a higher octane is a waste of money and will provide no benefit whatsoever.Regular Unleaded 87 octane. The use of a higher octane is a waste of money and will provide no benefit whatsoever.


If gasoline description is Super Plus then what does the Plus mean?

It means the gasoline blend has a higher Octane. Use the octane that the manufacture recommends for your car. If you are already using the proper octane fuel, you will not obtain more power from higher octane fuels. The engine will be already operating at optimum settings, and a higher octane will have no effect on the management system. Your driveability and fuel economy will remain the same. The higher octane fuel costs more, so you are just throwing money away.


What octane for a kx 100?

Stock can run 93 octane and if its modded you need 100 octane or higher if its a high compression build.


Do fuel efficient cars typically use higher octane gasoline?

No, higher octane fuel is only necessary for higher performance cars. Highly efficient cars can usually use the lowest octane fuels, because they are not designed for performance.


Can you put octane booster to 87 octane to get 91 octane or higher?

Yes you can. It will always be cheaper to just buy the 91 octane though so you'd be wasting your money.


What is 4 star petrol?

Answer It is to do with the octane levels in the petrol. the higher the star the higher the octane. It used to be 2,3 and 4 star but now its mainly unleaded.


Is it harder to ignite a lower or higher-octane gasoline?

It is harder to ignite higher octane gasoline - the octane rating expresses the compound's resistance to pre-ignition (often called "ping") Low octane fuels tend to 'ping' more than high octane fuels because they ignite more easily.


Why does octane have a higher boiling point than pentane?

Octane has more carbon atoms than pentane.


Does higher octane gasoline give you better gas mileage?

No. If your car runs well on a lower octane gasoline (i.e. no engine pinging or knocking), then putting a higher octane gas in your tank is just wasting money...


Can I use Gasoline octane 91 instead of octane 95 for Lexus 350 ES year 2009?

You should be fine with 91 octane. The higher the octane, the more you engine will like it, but 91 octane is enough for your ES 350.


What type or fuel 87 or 89 do yo put in a hyosung 650R motorbike?

the higher the octane the better, especially, if your in a state which has 10% ethanol in the gas...higher octane does NOT produce more power, but rather, increases a fuels resistance to pinging/detonation..higher octane, will not hurt anything, it can only help save a motor from detonation...when I say "high octane" I`m reffering to no higher then about 93...


What octane does a 1995 Toyota 4Runner need?

A 3vze engine will take anywhere from regular 87 octane, up to 100 octane race gas. However what is your purpose to using higher or lower octane, Using regular, plus, or premium will work well. however higher mile engines would prefer 91 octane!


What is the lowest octane to use in an AD wagon?

87 octane regular is recommended. Using a higher octane is a total waste of money and will provide no benefits whatsoever.


How do you stop engine ping?

Higher octane fuels.

What is the best octane for a Chevy Camaro with a 305 engine?

Regular Unleaded 87 Octane is sufficient. Buying any higher octane is a waste of money and will provide no benefit.


Does 91 octane gas have more additives than 87 octane gas?

No it does not have any more additives. It has more octane and that is all. If your engine is designed to run on 87 octane then using 91 octane is a complete total waste of money. The higher octane fuel will provide no more power, fuel economy, or any other benefit at all. In fact your car may be harder to start with the higher octane fuel due to it's higher flash point. It is a total myth that higher octane fuel is better. It is only needed in a high compression engine to prevent pre-detonation and that is the only purpose it serves. Use exactly what is recommended by the manufacture and save your hard earned money.


Fule for caprice classic 85?

An '85 Chevy Caprice Classic takes standard unleaded fuel (87 octane) unless if it is a Diesel engine. Higher octane is okay to use, however I am uncertain if it is okay to constantly use a higher octane.

For a motorcycle engine, premium unleaded is the best octane of fuel for most bikes. This is a 91 or higher octane depending on your geographical location. The higher octane the fuel, the more cleanly it burns. This will give the motor better performance.


What is the octane number?

The octane number is a measure of performance of a fuel. It is measured relative to pure isooctane which is given an arbitrary value of 100. It is possible for fuels to have an octane number higher than 100. The higher the octane number the more compression it takes for the fuel to detonate. Higher octane fuel is used usually in high performance vehicles where the engines have higher compression ratios. If the octane number of a fuel isn't high enough it can lead to engine knocking this is where the fuel detonates before the fuel is at its maximum compressive state in the engine, this can cause damage and lower performance.
