Available Porsche approved oils? Ryan_K - Tuesday, 6 May, 2014, at 10:47:46 am |
Any approved oil (look for A40 on the bottle's label) is just fine. If you live in an area.. MarcW - Tuesday, 6 May, 2014, at 11:14:54 am |

A source I have indicates ZDDP can breakdown the oil at high >6000RPMs. High levels of this stuff... MarcW - Tuesday, 6 May, 2014, at 3:31:33 pm |
When hydrodynamic lubrication fails, you want something like ZDDP (or boron or titanium or....) grant - Tuesday, 6 May, 2014, at 8:58:19 pm |
Do you really believe if the oil film breaks down at any speed/load that something... MarcW - Wednesday, 7 May, 2014, at 1:24:17 am |
Yes, because testing proves it grant - Wednesday, 7 May, 2014, at 7:58:53 am |

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.

Nope. Only testing i know of is: grant - Wednesday, 7 May, 2014, at 10:51:41 am |
