So would it hurt my car if i added a little 100 low lead fuel to my tank with my gas? I know the older muscle cars can use it...but they have cast iron engines...but i dont know what it would do to ours...

 

no lead! bad for cat etc

 

Don't do it.


You need to tune in order to get the benefits of higher octane anyways.

 

haha

 

Thats what I thought. I wasnt planning on doing it though..I was just curious!

 

I believe it is bad for your cat and the environment.

 

I am curious what kind of advantage you think you will gain from adding "a little 100 low lead fuel to my tank with my gas"? Why? and where did you find that information?

Do you have a catless dp and a tune?

 

It clogs up the cat, and damages O2 sensors. Dont' do it.

The 100LL stuff seems to be fairly hard on O2 sensors from my experience, buddy of mine ran C16 all the time, never had a problem. Another guy ran 100LL once in a while, was fouling O2's on a monthly basis.

 

like i said again..im not and wasnt goin to do this...i was just curious...heard some people mention doing it to their cars..i didnt think it was a good idea in the first place
