ok what to you guys think is the best weight oil in 100 degree heat fora moded 01 tt?? thanks in advance

 

5W50 Mobil 1

 

thanks larry i am running that now with no probs....

 

I'm personally using 15W40 Turbo Diesel Truck formula, but I don't disagree that 5W50 is a great solution as well...

Kevin says not to use 15W40 in the 996TT.

 

Most of the race Porsche's are still running 0w40.

 

Most "race cars" get rebuilt on a regular schedule, long term wear is not a concern for race cars.

Not that 0w40 is bad or not, it is just that civilians should not copy race cars without considering all the factors.

I'm just saying....

PS Steve- running 5W50 Mobil 1.

 

That's 180 opposite ofwhat was posted on his site by an engineer he asked to come chat with us about the 0w40 formula change issue! 15w40tdt was strongly recommened by Kevin and his guest poster!

Mike

 

Sorry Mike, I didn't see that post and have seen Kevin post previously not to use the 15w oils.

 

I thought Turbo Diesel oil is usually 5w40w not 15w40w.

Todd K likes 20w50w.

 

If you speak of the Flat6 thread with Doug H, I think you are mistaken. Kevin recommended the 15W40 for the 993TT (air/oil cooled) not the 996TT. AFAIK, they suggest 0W40, 5W40 and 5W50 depending on environment.

 

That's what I thought Kevin said too. Seems I remember reading that the oil acts as a hydraulic fluid in the VarioCam actuators and that they are sensitive to the oil's weight. I could be wrong though.

 

Damn I'm getting old and memory is starting to fail me... It is 5W40TDT oil that I'm using...and was recommended. Although Doug did state that he thought using Shell TDT oil would also work well...

Oil type should be dependent upon driving type, change frequency and the environment.
Since I change my oil every 1500 to 2000 miles and I live in So. Cal where the average temp is 72, I use 0-40W.

One of the most important things is to always ensure that the oil is up to operating temp before exceeding 3400 RPM’s.

The best advice I have herd yet is not to follow race car habits.

 

The reason that thread over on FTS was started was due to the change in formula for the 0W40 and why experts were recommending using another weight...
