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 ?

In most US fuel terminals all gasoline starts the same. If it will be Shell it gets the Shell addatives....if Mobil/Exxon it gets their package etc. The V10 was designed to use 87 octane....use it as you will not increase mileage using premium.
