Interesting... any personal experience with this?


I use it every time I have to smog my 83 Silverado with 223K on the clock, in the 33 yrs I've owned it she hasn't failed a smog test, I like to run one bottle thru a tank of gas, i'll add a second bottle, refill and go thru the test, works for me

E85 works great! So does half a gallon of mineral spirits and cutting back on engine timing. Turns that exhaust system into a mega hot afterburner.

For the other readers of this old post: Unless you've modified your engine to take E85, don't forget to fill up with "normal" gas ASAP to dilute all that E85 pronto.
