Try to use regular 100% gas with no ethanol in it (if you don't already) if it is available to you. I know some parts of the country only have ethanol blends.


I wish that there was no ethanol in the gas but regular has 7-11 percent and it was only in a few city's that required RFG gas but since 2008 I think it up to each state because they have to stop using mtbe, but there is a shortage of ethanol. I know that bp is experimenting with butanol but haven't heard any thing in a while.

 

1.) Good injection cleaner
2.) Fill up with Chevron hi test and shift @ 3.5k-5k rpms
3.) Do not worry about this tank and MPG
4.) Fill up and take a road trip 200 miles away get a cup of good coffee and come back home. 38MPG enjoy
