Just installed E3 spark plugs and started to look closely at my Average MPG.... Looks like I'm between 10.8 and 12.1 depending on the amount of local highway driving. Around town its right around 11. Dont notice any significant change since I swapped the plugs (three tanks of gas) if anything it went down. Anyone have some of their numbers that thay would share as mine seems a bit low??? Thanks, Bill
