Have you noticed that our trucks are getting worst gas mileage now that th price of gasoline has sky rocketed.. Well I think that the oil Companies are cutting back on some of the ingredient's to make a good quality fuel. To much pressure on them to keep up with there production number's and getting ready to start heating oil production that they are cutting back on the stuff that makes for a good product. I'd sure would like to know what the Vaper pressure is right now on reg Gasoline. It should be below 9 percent. Are they cutting back to the winter grades too soon by adding more MTBE and Butane.

 

maybe it is the area in which you live..i have been getting great mileage...with the AC on...coming back from the nationals, i got 240 miles, and im only to a half tank....

 

I have not been getting any different milage, maybe its time for a tune up??
