Whatever. What about when vehicles that were spec'd for 5w30 were then suddenly back-spec'd to 5W-20. Didn't the engineers know what they were doing when 5w30 was originally spec'd for those vehicles? And then Ford changes back to 5w30 again for some applications. I believe people can read the writing on the wall.
People can think for themselves and decide whether or not they will run these CAFE-driven oils (5W-20, 0W-20, 0W-16, etc).
I used M1 5-20 in 1978 in an engine calling for 10-40. No CAFE then and the 5-20 performed very well. 0-20 still performs well today. I have put about 400K on Ford engines with 0-20 in recent years.
This is coming from the person who also said people should use what is spec'd for the vehicle and that he would use 10W-40 if the owner's manual called for it. And regardless of your constant posts about how long you've used Mobil 1 5W-20/0W-20 or whatever, these thin oils like 0W-20, 0W-16, 0W-12, etc, are CAFE driven.
