The professionals that post here seem to think that the 0W- is not a good choice, as seen in the many "best oil" threads over the years.

JFP's posts here convinced me:

Not to throw fuel on the fire

100's of thousands of people run 0w-40 in their Porsche as recomended
I'm not an engineer, but it would seem that having an oil that acts thinner would be better for startup.

BTW, that there is over 6 years old and as many have stated, the oil companies reformulate their product from time to time, so it is highly likely that the products have changed since 2009

At the end of the day, drink whatever flavor Kool-Aid you like

There are plenty of oil threads over the years and plenty of other forum's where it is discussed. I'm not sayin' "Thou shalt not use M1 0W-40." Just that in many opinions, it is not the best choice. It's what I put in my '01 a couple months ago. My '99s are running Castrol Edge 5W-50 and 10W-40. -Good sale price on all three and for my old, fully depreciated Boxsters, I really don't care that much.

For me, Kool-Aid is way too sweet and packed with unhealthy ingredients that are more about marketing than providing anything useful to your body. /Avoid.

I drink XX
