was at etown today, put about $25.00 of 116 in the car..ran the car about 4 times
as i was leaving loading the trunk back up i noticed what appeared a white
chalky residue on the tip of my exhaust...any info on why???
fyi--was also on my buddies sr20det

 

is it because it low-leaded?

 

What kind of gas was it. The stuff I buy usually has lead in it and is for use for off road only. I usually mix 110 and 95 at about 50/50 ratio.

 

Yeah must of been running real rich, but yeah thats the same stuff that sticks to your O2 sensor and messes em up.. Anything beyond 109 is leaded fuel ...
