Gas Questions

[bighops2000]

1. HAS ANYONE NOTED A DIFFERENCE IN THE 3.2V6 USING 87 AS OPPOSED TO 89? i got the same results on both

2. IS 93 OCTANE REALLY WORTH THE PRICE? I've never bothered to put it in.

3. DOES ADDING OCTANE BOOSTER TO LOW GRADE FUEL MAKE IT COMPARABLE TO 93?

4. IS THIS NEW ETHANOL FUEL SAFE TO USE? I heard its just an 85 octane.

5.IS THE MYTH ABOUT USING 93 TRUE? U HAVE TO KEEP USING IT? HAS ANYONE ELSE HEARD THAT?


pitch in yall!!!

Your Rodeo is designed to run on 87 octane fuel. Adding higher octane fuel gives no benefit. If you've been running higher octane, some say that your computer "gets used to it" and that you can't switch back. Thats a load of BS. The computer will just get used to using 87 again. The only thing octane is for is to prevent knocking and pinging. If you're not knocking and pinging on 87, then higher octane is a waste of money.

Not true.
Buying higher octane gas results in a lighter wallet allowing you to go just that little bit faster.

now, that is funny...!

Don't forget the sticker that says "Powered by 93 Octane". For every 1" of sticker, you get 10hp!... Now seriously, I don't think its worth putting that crap into this engine. I mean its not like you're running 1/4 miles where that little boost might give you an extra .001 second time.

Thats the thing, there is no extra boost. The only power advantage to using higher octane is if the engine knocks/pings on the lower grade fuel, which robs power. Knocking/pinging happens when the air/fuel mixture burns pre-maturly, while the piston is still moving up on the compression stroke. Advanced timing can cause this, but thats usually not an issue on newer computer controlled cars. You can't adjust the timing. Higher octane fuel simply resists pre-mature burning. Thats it. Theres nothing more to it. Race cars use high octane gas because they usually use very high compression engines. If they used 87 octane in a high compression engine, the fuel would ignite simply by compression and the engine would soon be damaged.

Diesel engines are a different story. The have no spark plugs and rely on heat and compression to ignite the fuel. Thats why they are so noisy.

Also, some more stuff I've learned about gasoline: All gas is the same. Yep, you read right. Doesn't matter if its Chevron, Exxon or gas from the local mom & pop, its the same gas. The only difference is some companies put different additives in their gas and try to convince you that their gas is worth the extra money. Also, the octane rating bears no reflection on the quality of the gas.

what about numbers 3 and 4

Octane booster does work, but again, no benefit to Rodeos.

Ethanol is safe to use, its methanol you want to stay away from.
