Mostly Chevron or Shell. Sometimes 76 just cuz it's right by my house. :D Chevron gas has cleaning stuff in it...I think Shell's does too. Supposed to clean your engine as it burns....so they say..hehe:D

 

Just an update, if you're using Arco, or other 10% ethanol gas providers, and it's not mandatory in your area, stop. We've now exceeded the brake even point on gas prices and your getting less energy for your dollar with E10 than you are with raw gas. Actually, we've been at that point for some time now.

 

Chevron When Ever My Wallet Is Felling Heavy. I Calculated About 19mpg Mixed

 

Costco has ethanol in their gas now, I saw the ethanol stickers on the pumps at my local Costco Friday.

 

I have one motorcycle that will not run on oxygenated gasoline, and another I have to mix in some racefuel to get it to run well if I accidentally get that garbage.

my Fuel injected Elky runs bad on the stuff too because it runs open loop

oxygenated fuel is intended to lean out poorly tuned cars to try and help cut emissions. a byproduct is that it slightly raises octane as well, so the base can be of lesser quality. if your car or motorcycle is tuned properly and does not have an ecu that will readily adapt, it is bad.
