So I filled up my ex500 on Shell about a month ago & seemed to get about 25 miles more on the tank.
Then when it went empty, I went back to my old standby Union 76 gas. It ran good, but the mileage dropped back about 20 miles.
After that tank emptied, I filled again with Shell and now back up to achieving about 20-25 miles more on the tank
Question: Did Shell reformulate with a corn-gas blend that is making a difference? Same price as Unocal....but if this keeps up, I'm switching to Shell.
GL
btw: this is gas coming from NorCal....as far as I can tell.
