Has anyone had problems with their stock cat due to running a lot of race fuel? The reason I ask is b/c a friend of mine with a lightning had to replace all 4 cats due to running race fuel, very expensive! Any insight is appreciated! -- Johan

 

as long as you dont run LEADED fuel you should be fine. I run 100 - 101 in my car at the track and no problems...the car loves it ! Leaded fuel will kill your cats in no time flat !!

 

Agreed

 

Thanks!!!

 

and leaded fuel will kill your 02 sensor even if you don't have a cat...

 

and 100 locally, but be prepared to pay and pay!

try running "import fuel" or c16 or c23... the price of those will make your MINI jaws hit the FLOOR!

 

Whats a cat?

 

but goes "Meow" instead of "Woof"

yea $5 for 100 and $7 a gal for 104 (un-leaded) -- Johan
