What is the best 4 wheel drive motor oil?

Answer 1

I use mobil delvac 1300 15w40 in my 4x4. It's a heavy duty oil that is great for high mileage engines>

Answer 2

Any good solid motor oil should work fine. The 4 wheel drive really makes no difference it's in how hard the engine has to work.
The synthetics are sold as a better product than the standard oil. If you use the 4 wheeel option a lot that may be something to consider. Stay with the major brands.

Answer 3

You have choices, within the mineral brands: Havoline, Valvoline, Quaker State, Pennzoil and Brad Penn for guys who like Pennsylvania oil.

Full synthetic brands: Mobil 1, Valvoline, Quaker State, Havoline and Pennzoil is the least expensive of all. If you "supposedly" want to step up a notch @ $2.00 - $4.00 per quart: Redline, Royal Purple, Amsoil.

Remember this: None of the Craftsman Truck, Bush series or Nextel cup guys use the higher priced oils I've listed above.
Joe Gibbs uses Joe Gibbs Racing oil, Hendrick uses Quaker State, Penske - Mobil 1.

Stick the the viscosity that's printed inside your glove compartment handbook. Light viscosity 5W-30, 5W-20, is pumped to critical engine parts quicker. Thinner oil cools your crankcase more efficiently, and your truck makes more power. The oil pump works very hard when pumping high viscosity molasses robbing you of horsepower.

For the heck of it go to Joe Gibbs Racing oil to see what oils they use on the engine dyno's, qualifying, restrictor plate racing and when the plates are not used. I guaranty you'll be shocked.

Answer 4

Use all Royal Purple products oil, power steering fluid, radiator additve, gear lube, and grease. You will LOVE this stuff it will free up horse power just by changing to it. I use it all in all my vehicles. I save gas, wear and tear. This stuff is great. Look at some of the reviews.
