Still haven't noticed much MPG gain by switching over to AMSOIL oil, gar oil and EA Air Filter. Also filled up with 89 Ethanol Free Gas at $4.19 a gallon. haven't seen much a big difference in MPG gains. Stuck with 15 average. No more complaining about MPG from me LOL
Guess I'll just stick with Mobil-1 full synthetic from Walmart, 87 Ethanol treated gas, and save my money.
