Engine noise not withstanding...

I never experienced worse and excessive cold (+10F) startup and warmup racket than with this mobil 1 AFE - Its coming out of the sump. Wasted my money. A servicable M1 oil?> M1R4T.
Some blame apportionment: Three ILSAC req/spec changes in ten years? Something bad's happening behind the curtain ...

Not really, a 0W30 can only be had in a synthetic, so they are shear stable as they have little if any VI
a 10w-30 syn perhaps has no VII, but it has been somewhat established that the wider spread syn oils may still have VIIs.
0w-30 has a greater chance of VII than 5w-30, the wider the spread, the more robust a base stock is needed to meet it, or the more VII is required.
Doesnt mean that either shear anything like a dino oil will. Blouestream's point isnt necessarily relevant to syn 5w-30 vs syn 0w-30...

What's the problem with modern VIIs anyway?

I would have gone with 0W-30 if my wal*Mart had it. I settled for the 5W.
I'm about to do a semi-qualitative viscosity check at +10degF M1 AFE v. MTD tractor 5w-30 SJ.

After experiencing poor fuel mileage with the last three tanks(and NEVER before) I switched from Shell to Mobil fuel yesterday and - what a diff. Smooth and nice drivability - Even cold start noise is less. SO, the shell and the othet Irving I have been using may be misformulated. Hope my gas mileage gets above 33mpg on this tank - It was alway better than 36>38 even in the coldest winter weeks. The AFE is staying in for now and getting better every week it's in there.
