I used to get 25-30 miles to the gallon b4 I replaced my clutch without ac on and VTECing it here and there. Ever since I replaced my clutch with the ACT Street Disk with the Xtreme Pressure Plate, I've been getting 30+ miles to the gallon even with a VTEC here and there. Could it be that the new clutch helped improve it in anyway or is it that the weather is just cooler and makes the car run more efficiently?
