What kind of mileage are you guys seeing with your hubs locked in? Here in Michigan I keep my hubs locked in just about all winter except for on long trips. I lose about 1-2 mpgs, but just curious to what other people are seeing.

 

I think it all depends on the stop-and-go, and of course, what the gear ratio of the diff is. The lower the gear (higher number), the more torque it takes to spin up the driveshaft that isn't doing anything.

I never really noticed a whole lot of difference with mine. If anything, winter/summer gas does more damage to the wallet than anything else
