The higher octane gas is the more resistant it is to detonation then lower octane gas. So in high compresion engines where detonation can easily occure it's best to use high octane gas.

But that only applies if your bike is SUFFERING FROM detonation. If your bike isn't, then you are just throwing money down the toilet, and making the oil industry even richer.

Here's the best advice I can give you on the gasoline subject:
Next time you hit reserve on your bike, go to you preferred gas station. Add 1 gallon of low test. Ride until you hit reserve, making sure you go through all the extremes you can go through.

Add 1 gallon of midgrade, and repeat. Then finally 1 gallon of high test.

After trying all the various grades, use the one that gives you the best performance, and the best mileage.

BC.


I didn't do it, I swear.
And even if I did, what makes you think I would admit it to you?

The shop where I bought my J1 recently had regular unleaded in the tank. I know of several people who won't use unleaded and go for the High Octane (premium unleaded as it is known here). Is there pros or cons with using either type of fuel?

It's a 2000 ZX6R. Would using unleaded cause any engine damage over time? I've heard of some engines developing a knock from using the regular unleaded.

Thanks for any info.

"The cylinders themselves have a redesigned 'pentroof' combustion chamber that features an increase in compression from 11.8:1 to 12.8:1 the result of which requires the use of at least 90-octane fuel."

I don't want to go get my manual out, but I'm sure it says to run 90+.

J1Aussie,
You must run 90+ octane. You can NOT run leaded fuel if you have you stock pipe because it has a cataylitic converter in it. I just use high test 93 octane regular pump gas. They dont sell leaded fuel at the pumps. If you want leaded fuel you'll have to buy it an drums or fill er up at the track. Also the bike was actually run from kawasaki with 95 octane gas. So I think that 95 octane might be the best for track days. So i think you can buy 94 octane gas at the pump form sunoco.

Thank God for Guardian Angels... Especially This One!

Once you get rid of the stock exhaust, you should be able to run leaded with no problems. What is the highest fuel you can run without the catalytic converter? Any ideas?

I want to clear up some of what you mentioned. Either you made a typo, or you just aren't sure.

I think you may be getting your gas confused. Regular unleaded gas is like premium unleaded gas. The only difference is the added octane level in the premium. The people that you mention that won't use unleaded... Do they use leaded gas, then, because premium (high octane) is unleaded as well.
