I mean no disrespect here at all guys. I just wish we could get some new Ford Trucks down there so ya'll could tow and beat on them in the desert only running Ford spec. 5W-20. It would be interesting. I'd just like to see Ford put through the Outback with towing and hauling with the Motorcraft 5W-20 and Mobil 1 0W-20. Keep us informed. I'm sure it's been done. Any info?? I haven't seen a lot on this with towing at high temps.
