I was told by a friend with a '99 996 that I should use Mobile Synthetic 15W 50. The Porsche owners manual suggests 10W 40 for my temperature If I remember correctly. In your experiences which has proved to be the best oil for your engine. I would never put mineral-based oil in but I’m not sure about the Synthetic weight. I live in San Diego, CA with very temperate weather generally above 60 degrees year round so I don't have to worry about - temperatures. Thanks for the help!

I am also in San Diego, and I feel that since we have cuh normalized, constant tempatures, that we are in the best position to use quite a thick recipe for oil. I specifically use Amsoil 20/50 racing oil. Its red, so when its not so red anymore, I change it, and its supposed to be long drain, so if I by chance have to go 5k with it in there, I'm okay.

At walmart, 15/50 mobile is 4.50 a quart. The way I see it, my 7.50 a quart is not that far off, and for a better oil, which is proven in various tests. I bought that "preffered customer" thing with Amsoil, so I have that 20% discount thing. I buy enough with two 9 quart cars!

Use the factory recommended Mobil One 0W-40. You can get it from your local ExxonMobil oil distributor (check Mobil's web site).

Using a heavier oil is unnecessary and will cost you some power. Also, the thicker oil is not as desirable for cold starting.

FixedWing,
Have you been able to purchase Mobil1 0W-40 from a local ExxonMobil distributor?
I have been unsuccessful here in MA (Boston). Seems as though they only sell 0W-40 to dealers. Every retail outlet who sells other grades of Mobil1 tell me they can't even order it for me.

Mobil 1 0w-40 is now available at Autozone parts stores.

Yes. I bought four mini-cases from the distributor in Connecticut, L F Powers Co in Waterbury.

I paid retail though had I bought a pallet then they would have given me a discount.

I'm surprised. You are the first person I've heard reporting a problem. In fact, friends also buy their aviation products that way. So if they don't want your business try another one. To find a distributor look here:

Im hearing a majority response for 0w-40. I am not very informed on the specifics of oil weights. What does the 0W stand for? Does that mean it is a very thin oil? Same for the 40. what would be the difference between a 0W and a 10W? Thanks for the help
