Shouldn't do any damage with such a slight increase. The owners manual gives a standard but I don't believe it tells you not to use something more. That's just to let you know what the lowest level is. Often times using that level will cause the knock sensor to activate and retard your timing and in turn reduce mileage even more.
Now the question will be how much better does the mileage get if you go back to Mobile 1. Of course 32.50 is a lot to offset over a few thousand miles. ----- Original Message ----- From: "Lenny McHugh" <[EMAIL PROTECTED]> To: "handyman-blind" <[email protected]> Sent: Sunday, August 24, 2008 1:36 PM Subject: [BlindHandyMan] fuel question for the car guys > Hi All, > Just changing mail delivery for all of my lists.
