Topic Grant--a question about oil testing |
Available Porsche approved oils? Ryan_K - 9 years ago |
Any approved oil (look for A40 on the bottle's label) is just fine. If you live in an area.. MarcW - 9 years ago |
Do you really believe if the oil film breaks down at any speed/load that something... MarcW - 9 years ago |
Yes, because testing proves it grant - 9 years ago |
Incidentally, haste sometimes precludes good writing. I really appreciate the objectve..... grant - 9 years ago |
A40 doesn't specify any rating... MarcW - 9 years ago |

M1 0w40 is available everywhere and is on the list.
As is edge 5w40 SPT (that's the old syntec formulation)
I am often the one advising some people to run thicker oils, but please focus on the trade-off. For most daily drivers, thinner may well be better - it will flow better. For track use however, thicker oils may be necessary to retain a film strength at 6000 rpm, sustained WOT for 20-40 minutes at a 50% duty cycle or so. Temps get high, as do mechanical pressures.
You can worry or not about A40. I read the specs and work from there. in warm climates for hard-driven cars 10w40 is probably a very good choice.
The key is ACEA A3/B4. High TBN is also good.
