Re-Confirms mobil 1 is the king of the cold cranking test. Also not sure I'd consider this a "best selling oil test" as it included M1 AP!

I'm not sure why the OP titled this thread as "Best Selling" as PQIA makes no such claim and I doubt any of the full syns listed are overall best sellers when there are cheaper conventionals that must sell more...
All of these oils had been tested previously. PQIA picked these 6 to retest. I think they picked these 6 because they are best sellers. So, I say prove these 6 are not best sellers if it's such a big deal to some. Why not concentrate on the results instead of why I titled the thread what I did?
