The problem isn't left-to-right speed differential, but front to rear. This has been covered many times on this forum.

Now running 150miles on dry pavement highway speeds? Unless there is reasons of Needing 4x4 I would not recommend it. Due to well higher gas consumption

Running in 4wd actually won't affect gas mileage much, if at all, with our trucks. All the drivetrain components are rotating whether it's in 2wd or 4wd.

The short of it is don't run in 4wd if you don't feel it's necessary. There's no need to "prepare" for situations by engaging it miles before you have to or leaving it engaged during extended dry driving periods between slick spots.

Don't turn on dry surfaces that don't allow sufficient wheel slippage while 4wd is engaged.

Rain doesn't count as sufficient.

Roads don't instantly go from not needing 4wd to requiring it or you'll be stuck...unless you're headed straight for a 4ft snow drift.

Just use common sense.
