Regular or high test gasoline
I have a 24' motor home with a Ford V10 gas engine. Was wondering if anyone has gave it an honest test for gas mileage using high test vs regular. Is it worth the money difference ?

Use what the manufacturers recommend. If they say 87 octane, then use it. As far as comparing mileage of different brands, those figures can vary even if you use the same brand of fuel.
If you look at the pump next time you buy gas, read what the "ethanol" sticker says. It usually says something like "UP TO 10% ethanol. This means that it may have 2%, 5%, 8% or 10% ethanol. The actual amount will vary and the more ethanol that is in that particular station's tank on that day the lower your mileage will be. Come back next week to the same station and the amount of ethanol may be less, who knows?
