Last week, I had a problem starting my car up so I had to jump start, my engine light was on, and it was a mess.
A friend recommended that I put in Isoheet with my fillups.
Sure enough, after a while the engine light disappeared.
Do you guys really think it's because of the Isoheet?

 

no. I think you had a bad tank of winter mix fuel, and after a few tanks, you had decent fuel in the tank again.

just my .02
