but of course the MT cars don't have the ability to disable the rear drive so it's a moot point.

they don't now, but the older ones used to and they're nearly identical in many respects to the newer ones. like i said, i've done it to auto's and manuals. manuals, same story, no difference. the transmission has internal bits, center diff on manuals, and rear extension housing on auto's, that don't magically disappear when you run it in FWD. added weight and added losses to the rotating works.

 

if you want good gas mileage, get a FWD manual soob. they are out there, or they can be made to suit, and are capable of 35-45 mpg depending what models/trans you want. playing with your AWD soob to get a 0.04% increase in gas mileage is not the ticket, there's an option out there but you're looking in the wrong place.

15 or 20 Amp I think. Owner's manual has the correct spec.

Placing a fuse in the FWD holder grounds ("pulls low") a logic circuit input. Any automotive fuse that fits the holder will pass enough current.

Contrast this with the MT models which are 50/50 at all times (which also explains whey the MT models don't get any better MPG than the autos.) Presumably a MT car could benefit more from disabling the RWD, but of course the MT cars don't have the ability to disable the rear drive so it's a moot point.

 

Actually its one 50/50 when needed. Look at

where they decribe the subaru manual system. Thats another reason why ther e is no increase in mpg.
