What oil for 2.7 is best?
- Thread starter wblackw9
- Start date
Since having my 911T (1973) with 3 different engines (2.2T/2.4E/3.2) I have used Shell 10/40 Helix semi synthetic.
When I used mobil one in the 2.4 it leaked! Went back to Shell Helix Plus10/40 it didn't.
I have hillclimbed and road driven all the engines and never had a failure.
It is not cheap, esp if you have the serpentine oil cooler capacity to fill, but I never use anything else in all my cars (Yaris/Mini/400 bhp turbo Impreza hillclimber).
Will be doing the same in 2 weeks time.
Not sure if it is simply marketing, but the 'GTX 1970's Oils' are singled out on the shelved as oils for the Older Engines (by design, not wear).
I'll stick with the oil bob Watson told me to use in 1989...

My car is a 1977 2.7 911. It has covered 132,000 miles and going strong but what is the best oil to use? I see on another thread someone has an 1979 sc and uses 20/50. I thought this would be to thick but may be wrong. What is best?
Castrol Magnatec 10W40 seems to be a popular choice.
