TFI, Karl! I've kept receipts for every drop & penny that's gone into our '98 1.9...MPG = 28.982 over its 54,533mi. life-to-date.
BTW, it's getting Dinan's new Cold Air Intake & Stage II software installed this afternoon. I'm kinda anxious to see what effects they'll have on MPG.
: I was getting 27 MPG before supercharging. I now get...27 MPG! I have even gotten 33 MPG on the highway during club tours, with the supercharger.
: Why? Well I was always in 3rd gear, stock. I am now in 5th all the time. Also I'm not in the boost every minute the car is running. Maybe only 25% of the time (...well more like 30%...).
: The only comment I can make about fuel requirements is the local octane is too low. To really get the most from my supercharger I need a little octane booster.
