I need an alignment but its not bad and consistent across both tanks. Both tanks were E10 which seems to affect my 200sx more than my B13.
Now I am trying 89 to see if it helps any. Very ****ty gas in the NW.
Thats a pretty good gain
I think its helping significantly and is more than cost effective. If I bought a gallon instead of a quart it would be like 50 cents to treat each tank versus the $1.00 (roughly) it costs with the quart bottle.
I also forgot to add I had the car loaded with gear. on the trip to Everett. Full trunk, backseat, and some stuff up front.
