Hi,
After recording for a couple of months, I found the gas mileage of my 99' mystique with 2.0 Zetec engine is not good.
with half highway , half city driving, I can only have 11 L/100KM, which is even worth than my friend's 6 cylinder Malibu. Since it already has 90,000 KM on the odometer, maybe
I need a tune up?
If so , should I stay with the Motocraft spark plugs or with othe brand? does anybody have such experience ?
thanks alot
