It's been very cold this week and I added some cetane booster to my fuel. I think I added too much, about 50 gals worth for the 25 gallons in my tank. Is this bad for the car? Anyhow, I've had the car for 5 yrs/60K miles, and it has never run so smoothly since I did this. It accelerates faster and seems to have much more torque. Is this the effect only of the cetane booster, or could it be that it radically cleaned the injectors, or some other effect? I have added diesel fuel treatment before, periodically, to clean injectors, etc. but usually added only a small amount.
