RE: Gas Mileage running air conditioner
Hey Flossie, welcome to the forum. Can't see how an A/C can save milage in either application. In a car you are running a compressor with your serpentine belt when the A/C is on and that takes extra fuel due to increased power required to run the compressor. In an RV, I take it you mean a class A/B/C motorhome, it takes more fuel if:
a. you are running a conventioal car type A/C (above applies)
b. You are using an on-board gas powered generator to run your roof/basement motorhome A/C
c. both a. and b. A/C's are used
In all cases it is going to require some type of a fuel powered airconditioner to cool your car or RV unless you rely on open windows or some form of solar power/inverter to run an on- board motorhome A/C while driving down the road.
Not sure if any of that makes sense, but I tried. :bleh:
