Suspected cause

Considering that all the other oils on Porsche's approval list are 40 weights, I'd imagine the M1 5W-50 is probably a low 50 weight.

If you've got this far on M1 0W-40 w/o any issue and your 996 runs like a champ, then why do you think you need to change brands (and/or oil weight)?

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi guys! Not looking to start the never ending saga of oil's brand fight. I just need your advice on which weight to choose without getting too technical. The car is a 2002 Carrera with 132,000 miles, driven every day on sunny Miami Florida (average temps around 80) could get to 95 on summer and 50 a couple of months. Currently using Mobil 1 0-40 TIA! joelpirela

Have you had any engine problems at 132K miles while using Mobil 1 0-40? If not - why not stay with what seems to suit your car really well?

Transportaion Safety Board? I'm in the liking of going heavier in a blended oil like 15-50. It's warm here all the time and when it comes to lubes and failures it the hotter spots that need the heavy weight to reduce friction. So a blend of thin to get things rolling easy at start then the heavier for hot and heavy rolling and I'm happy. Being a member of Black Peace -no relation to green peace- for the preservation of natural oils please don't tell anyone I've gone to the dark side using synthetic oils now PS Good thing it wasn't synthetic oil the Gulf of Mexico BP rig struck or the damage would be permanent.

POST 11Original post

If you want a 50 weight, then there are 2 flavors of M1 5W-50 that are approved by Porsche. Considering that all the other oils on Porsche's approval list are 40 weights, I'd imagine the M1 5W-50 is probably a low 50 weight. Here are some things to ponder about. A thick oil will not cool as well as a thin oil. An increase in oil pressure due to an increase in viscosity does not increase flow. /m

I posted this link in another thread on the 996FL Engine Test: http://www.roadrunner-region-pca.org...il_article.pdf If you note the Porsche approval letter that gets sent to the oil supplier (last page of the article): If there was a formulation change to M1 0W-40, then they would have to go through the approval process again or it would not longer be on the Porsche approval list. /m

I can read the TSB but the TSB doesn't mention my actual conditions, being a very high mileage car in a hot humid weather but thanks anyways...
