The owners manual is usually a pretty good place to start. I'm also willing to bet the OP's Ford owners manual doesn't say anywhere to use TGMO in the sump. Especially since it doesn't meet the Ford specifications.
No it doesn't meet Ford specs. I suspect the next 4 months won't see temps above freezing and many mornings below -20. I figured the cold start benefits would outweigh any drawbacks since they are both 20 weight spec'd oils at running temps. Guess not.
I'm not up on Canadian prices, but here Mobil 1 0W20 is reasonably priced and always on sale somewhere. The cold flow and pumping specs are very good, and it is according to Mobil a replacement oil for 5W20 spec'd engines.
From their site:
Mobil 1 Advanced Fuel Economy is available in 0W-20 and 0W-30 formulations. ExxonMobil recommends Mobil 1 0W-20 for 5W-20 applications and Mobil 1 0W-30 for 5W-30 and 10W-30 applications.
If the manufacturer of my car recommends a 5W-20 motor oil, will I void my warranty if I use Mobil 1 0W-20 Advanced Fuel Economy instead? If your car manufacturer recommends a SAE 5W-20 ILSAC oil (starburst), we recommend either Mobil 1 5W-20 or Mobil 1 0W-20 Advanced Fuel Economy.
Mobil 1 0W-20 Advanced Fuel Economy will not void new-car warranties where an SAE 5W-20 oil is recommended. Mobil 1 0W-20 Advanced Fuel Economy can provide better fuel economy and better low temperature performance compared to higher viscosity oils.
--------------------------------
I'd feel a lot safer with Mobil 1 vs. TGMO if I wanted a 0W-20 oil in a Ford calling for 5W20. Obviously opinions vary. I'd be willing to bet Toyota doesn't endorse TGMO for Ford vehicles, but that's just a hunch.
