I put a bottle of the fuel additive in my gas tank and then drove to the gas station (About 1 mile or less away). When I got to the gas station, I filled up my tank. But on the way to the gas station, I noticed that my car started hesitating and not accelerating as normal. Then my check enpermanentlycame on! I hope I didn't permanently damage anything It does fine after the initial hesitation. Do you think it just needs to run through the tank of gas?
Sorry to hear about your marriage. Have you consider selling the car and get yourself a car that does not use premium gas? I too was going to buy something luxury but later decided that I don't need to spend the extra money. Ok, back to the subject. I too have a high compression engine (BMW motorcycle) and sometime trying to locate gas could be pretty complicated. What I've done is carry an Octane Booster and use mid-grade gasoline. It is for emergency only and when I do locate the premium gas, I fill it as soon as I can. I doesn't hurt to mix gas (mid-grade with premium).
ive always use the stuff since it came out i add it every time i think about it and it dont have to be added to a full tank of gas . it will not hurt anything if anything your car wasnt running right to began with. so have you change the fuel filter might help also. doesnt hurt anything at all
There are many reasons a check engine light comes on running low on fuel, loose gas cap or as you suggested, a high concentration of hard to burn fuel ( additive) in the tank it's not likely thoughBest bet is to have the car checked out, and find out the real reason the light is coming onAdditives have their place as part of preventive maintenance on older cars but newer cars are highly adaptive/ tolerant (thanks to modern fuel injection and engine management), and usually will not develop a problem until something is seriously wrong that requires actual repair/ attention
