oil viscosity ? for so. cal
Hey guys,
Is there a consensus on the brand and viscosity of oil for southern california? I have heard 5w-40, but isn't this for colder climates? Any input here would be appreciated. Thanks--Aaron[B]

15w-50 for synthetics and 20w-50 for the good dino oils.

There was an extensive oil analysis and discussion on Ferrarichat.com about oils conducted by a knowledgeable Doctor who's specialty was , of all things, the flow of blood.
The bottom line was that the problems with oil for street cars is that they are TOO THICK until they warm up. Many many minutes. Durring this time is when most of the engine/turbo wear occurs. The solution is to use 0W-30 or 0W-40 oils. Full synthetics only. As an aircraft mechanic I spent many hours in school in lubrication classes. All the info in this discussion made perfect sense.
I now use 0W oils exclusively even here in TX in my S4 twin turbo and all other cars.
Racing cars use a different set of rules where the performance of oil at elevated temperatures for extended times is more important than start up requirements. Thus the straight 40 and 50 Wt racing oils.
