Can you help me with the reasoning behind the inability of engine manufacturers to produce an RV engine that can get decent gasoline mileage.

Also, is it better to use premium gasoline compared to regular in a motor home?

How about synthetic oil as compared to standard oil?

Good show. You managed to hit possibly the 3 most prominent "dead horse" issues in the forum......ALL in one post. :B

It is all in here already but:

I takes a certain amount of energy to push a huge weight down the road......especially when the wind catching profile looks pretty much like a barn door (high wind resistance). There just ain't a lot more you can do with the engine itself. This is basic physics.

In all engine applications, you should use the octane that the maker recommends. One is not "better" than the other; it depends on engine design. These days, most are designed for regular. Paying for higher octane is just a waste of money.

Synthetic oil is arguably a little "better" but only by a tiny margin IF you change at the interval recommended for dino oil.
