At startup? The 50 isnt as relevant for startup protection as the the first Winter grade number is, and what your particular climate is. Startup engine protection relies heavily on the cold viscosity of your winter grade. Not sure if your attempting to troll or what, because you have yet to actually tell me where the flaw is in said knowledge. If the next response is anything but, I will probably move on to other, more important threads.

Not trying to be offensive at all. But when someone shares knowledge of something they have looked deeply into to help those with questions, theres usually better and / or more detailed responses then "You guys are all very off on your understanding of motor oils." How about you share your knowledge, instead of making a generalized browbeat of others, and leave some details as to how you came to that conclusion.

My point is simple. YOu dont always have to have a thicker oil if your going to be racing. Conditions are the biggest consideration and a thicker oil can do more harm then good in some situations. In my mind there is no need for a 50 in the stang. Wouldnt you agree?

I use a Penn ultra and it is better then entry level AMsoil in alot of test at a far cheaper price.

Yes I understand your point. This is exactly why I chose a non-shearing 30w for my own car. What you dont realize is why ford suggests the 50 weight. Its because that garbage shears down to a 30 if your actually going hard on the track in the summer time.

They dont expect it to be a 50 at running temp at the track. 50 would be overkill IF it stayed at 50. But it doesnt.

And, thicker oil like 50w doesnt mean shit for startup. 0w50 in harsh winter cold start = fine.
If you run 15w20 in the winter, its just as bad as 15w50. First number is the key for startup. Again, its the winter grade number that determines its cold start viscosity. If Ford's oil didnt shear 1/3 of its viscosity under tracking then they would be suggesting lighter oil. Period.

Obviously. I do believe amsoil to be overpriced.

Subjective really... how much is too much for quality? But when compared to other high quality oils, I agree its got a high price tag. Sucks.
