Would running the "race gas fuel concentrate be causing my spark plugs to look like this ? The car runs great with no issues. Scanmaster numbers are good also Thanks

That's what I thought I hope my 02 sensor doesn't look the same. Thanks for the reply
 
I get that color with boostane and torco that I use ..
 
Looks like the plugs back when I ran 104+ octane boost way back when.
 
The additive that causes this is MMT. Lucas octane booster contains it.
 
Same here I run 24 lbs at 18 degrees and I keep afr at 10.9/11.0 it flys , I love my torco .
Yea I use both torco and boostane on my non alky cars, I think there great, I think the Boostane has the slight edge tho,.... I went from 19#s and pump gas with 1.9kr added boostane turned it up to 24# and got 0 kr, I didn't push it past that..

Yeah I saw a write up cal Hartline did with the boostane I think he sells it now I wanna try it , he seemed to like it . I'll see if hartline sells it by the case .
