If I recall correctly, T6 is a 5W-40. Is the brand-to-brand difference in viscosity/flow between different 5W-rated oils when cold really noteworthy?
Depends on how much of a difference we're talking about.
so since the mobil1 is on sale for 5 dollars cheaper basically i should get that because even if the t6 is better the mobil1 is a very close second would that be fair to say?
If M1 5w40 is on sale and is cheaper, get it. You cant make a bad decision. Get the one that is cheaper. M1 is a little thicker than the T6 if it matters too you. I personally would not say one is any better or worse than the other. Both are top notch.

That's how I take it. I'd go with the Mobil 1 if it was $15.
