Gas mileage

Just curious has anyone found a difference in gas mileage using different brands of gas or different grades of gas.

Try to avoid gas with ethanol, AKA, "Winter Blend" (some stations are now using it year round). I get an extra 50+ miles per 19.2 gallon tank in my AWD SUV when I avoid the stuff. Pumps that have ethanol are required to have the 10% sticker right on the pump (it's normally a 10% blend). You can also do your homework ahead of time using web sites like Ethanol-free gas stations in the U.S. and Canada. Ethanol blended gas also makes the engine (??and generator??) work harder since it does not have the same potency.

You've got to be kidding me no difference in gas. Go to name brand station you will get better mileage these supposed cheaper gas stations they buy the cheaper gas and yes it's different. Also less mileage with ethanol no ? burns hotter in now if dont need premium it's a waste but yes better quality gasoline will burn more efficiently so more mpg.

The most effective thing that I have found to improve gas mileage is my foot. I have improved my mileage by $.50/$.80 a gallon.

We live in a city with two refineries -Tesoro and Shell. It is my understanding that they supply independent and name-brand gas stations for a large geographic area around here. The basic fuel is the same for them all, just the proprietary additives which differentiate to brands are added when the raw fuel is loaded into the tankers.

You may have noticed that tanker trucks with the fuel brand name on them have all but disappeared. In our area they have advertising on them for tribal casinos.

The calorific value of gasoline is the same no matter who refines it. Buy the cheapest. We usually go to Costco or one of our local tribal retailers.

gas mileage improvement

I will keep this as short as possible. We have owned a 2006 Tiffin Allegro on Workhorse chassis since new. four cross country trips during that time. Last few trips, since ethanol gas, mileage and performance (especially cold engine performance and mileage) have suffered. This year, while out west, I searched online for cures and found several sites about many products and decided to try Lucas fuel conditioner (partly because it is readily available at the interstate truck stops). It has cured the cold engine issues and I calculated our mileage for the 6,000 mile trip, based on fuel receipts and odometer and was very pleasantly surprised to have averaged over 9 mpg. Believe it or not. I have no reason to lie about it. Our trip was form Albany, NY to Albuquerque, then to Destin, Fl then back to Albany. I drove at 65 mph on the interstates. Two to three years ago I did the Ultrapower upgrade and added a cold air intake, which I think helped to keep the mileage at 8 mpg on the ----y ethanol stuff they call gasoline. Both of these upgrades did produce noticeable improvements on their own. Obviously, the Ultrapower improvement was much more noticeable. I think it is worth a few bucks on your part to give the Lucas product a try. It will also clean your complete fuel system. I do not work for Lucas products, in case you were thinking that.

NJ stations offer nothing but 10% ethanol year round. This accounts for the fact that the state's gas prices are (artificially) among the lowest; however, the mpg does take a big hit. For that reason I always wait to get out of my home state.

Since I hold to the speed limits or below, my mpg has gone from 8 or 8.5/mile to 12/mile!!!!
