Hi all, just getting my 928 running in after its been stood for 3 years. I've noticed it puffs of grey smoke at high revs roughly at 3,000 or when driving and revs over 3,000rpm. At idle its perfect with no smoke. I've just given her a oil filter/oil change using 5/40.
I did run her at low revs just to run her in after been stood.
Any suggestions?
Hi
Umm your oil is too thin...
Change it again for either 20/50 or I use 15/50 Full synthetic...
I tried 0/40 when i got mine and had exactly the same smoke problem....
05/40 IS FINE if you run a modern 911... but our engines were never designed for an oil that thin...its going past the rings and valve stem seals...
And more revs...more smoke...
All the best Brett
