What happens when...

What happens when you run a low octane fuel in a engine that requires race gas? What are the effects of this, and what are the problems it causes?

Your ride will run like **** and maybe blow rings

detonation... it will combust prematurely...

[300excrazy98]

so what damage would it cause and how much would it cost to fix one if was ran on pump fuel

[yellowzo3]

more than it would cost to just do the right thing and run race gas. after a while the price of buying race gas will grow old (unless you race) so you could just change the motor back so it runs on pump gas. but if its mean to run race fuel i wouldnt run anything else.

its a good way to take out a top end...

[400exrider99]

you will burn a hole in the piston, and probally badly scratch the cylinder, burn valves, and maybe even get shavings int he bottom end and destroy the rod, crank. you have to get a hole new engine, just because you wanted to save a few bucks by running low octane feul.

let me ask.......can you run race fuel in a motor that doesnt need it?

[7 speed]

Yes you can. It won't hurt it.
I run all my left over C-12 in my lawn mower.

Hey kenny!!!

I finally got a new truck bro!!

you will actually lose power if you run higher octane and the motor doesnt need it. its best to run the least amount of octane possible with out damaging you engine or it performance to much and your wasting your money and power.
