Alternatives to Mobil 1
This is an interesting treatise on the subject of oils for Porsche's. There is probably more information than most of us can use or digest. LN Engineering, those good folks who seem to have the definitive answer on IMS issues, seem to be rather down on Mobil 1 as the formulation has apparently changed in recent years. Hence, after reviewing their testing, I've decided to switch to Motul 300V which can be ordered from Amazon. Its High-Temp, High Shear rating is ~50% better than Mobil 1 which makes it superior for summer track work. Unfortunately, it's about 3x more expensive as well. LN has now stopped selling this product in favor of Joe Gibbs DT40 but I am told this is only intended for for cars without catalytic convertors. Over time it apparently will clog the cats quite significantly. I have not verified this with LN as of yet. Anyway, for those of you with an interest, here's the article. Best,

No, I went with 5w40. If you go about halfway down the article's page, there is a section that says in bold print, Do not run any 0w30, 5w30, or 10w30 oil in your Porsche, aircooled engines included! Hope that helps!

Update: This is the response I received from Charles Navarro who authored the article on LN's website. I will likely go with Joe Gibbs product since it's cost profile is significantly better than the Motul 300V.
"DT40 is not a race oil and is designed to be compatible with daily drivers with cats, however it can be used for the track with excellent results."
There you have it!

The article blends info for both air and water cooled motors. Just need to make sure whatever part you're reading is applicable to your situation. Best,

i guess all the 40 are good just stay away from the 30's and the first # is depending on your climate and what your doing and such .. Since I live in Alaska Im going with 5w/40 although 0w/40 would not freze as easy and warms up quicker..I think 5/40 is a good all around weight to use in alaska
