Welmoed - What you have done is exactly what I am trying to convey. You took out old, original-equipment parts and replaced them with something else and got an improvement. I don't doubt that you got an improvement. What you have not shown is any improvement over NEW original-equipment parts with the parts you put in. Who knows - you might have put in brand new original equipment parts and got 30 mpg on that tankful instead of the 27 you measured. -- Mike -------------- Original message from "welmoedj" <joe.dalton@xxxxxxxxxx>: -------------- > I can do nothing but agree with John's arguments. > However to silence the comments I will provide data in the near > future. > Since I bought the car I kept track of mileage and fuel quantities > used. > Over 5500 Miles that resulted in 22.5 Miles per gallon. > I now will first drive around enough to have more miles and gallons > from the moment I changed coil and cables. > The first full tank however already showed a better fuel consumption > (increase of mileage up to 27.05 per gallon).
