I used The Outlaw fuel additive last weekend and ran the car without (oops) a full tank of gas. The next time I went to start the car, it took several tries before it would start. Each day, this became worse. I refilled the tank of gas after 1-2 days. Now my car will not start.

Any idea if that type of a fuel additive would foul my plugs? Where should I start? It cranks, but will not turn over...

Run a tank of premium (God forbid the price) and change the plugs. You loosened up a lot of carbon deposits in the cylinder head and fouled the plugs. It will be over soon. Good luck

PS stay away from Outlaw.

Suggested Repair

Run a full tank of premium fuel and replace the spark plugs. The additive likely loosened carbon deposits that fouled the plugs. Avoid that fuel additive.
