If you take a look at my mileage, you will see that I have a few tanks in the log. The worst one was being nice to the car. No boost, slow starts, watching lights, etc. Yielded 10.4something KMPL. The next tank, before I got tires for the car, was a lot of boost, climbing a mountain, and not really being nice to it. Yielded me 15.4 KMPL. The tires were a little mismatched when I bought the car; 165/55/14 and a 155/65/14, and I filled up early on the last tank to kind of reset after buying new tires and an alignment. I used some Fuel Power Plus for the first time on the third tank, and a stronger dose on the 15.4 tank. That’s a lot of difference. Is it because I didn’t have much throttle on the 10.4 tank, and more throttle makes better mileage? What am I missing?
