79 928 S oil
Hello,
I just bought a 79' 928S. It's my first Porsche and I have a question. What would be the best oil to use in it. I appreciate your help.

Hi Hai
I didnt know there was such a thing as a 1979 928S. Your PO must have put the spoilers on the front and rear of the car and 16" flat disc wheels to upgrade the look of the car to an S model. Perfectly fine to do. Welcome to the Old Buggers Club or the OBC as its called.
I put Mobil One in mine. Its was recommend to me to use 15w50. But i got 5w30 in it now and it seems ok to me. No leaks and after 2000 plus mile on the change its not burning it either. After reading about what ed ruiz's does with Mobil one in his GT, I think i will try it his way. Its a few threads down the list here

I use Castrol GTX 20-W-50 in my '79. I had previously been tempted to go with a synthetic, though tales of leaking seals on older vehicles swayed me from trying it.
In either case, I'd recommend (as does Porsche) going with a heavier weight oil due to the higher compression on the 928 engine.

I know what you mean. This car is really confusing. I didn't know if it was a real "S" or not. The car is a Euro so I thought maybe they made it overseas before it was made for the USA. I did a lot of research and the car seems to be an "S", but I don't know.
I went to http://porsche.theautobahn.com/models/production/928/
and they show an "S" was made in '79.
Oh well, thank you both for your information. I really appreciate it.

You can tell if you been suckered by checking the engine code. If your engine is a M28 01 or M28 02 you have a nicely dressed 1979 euro. M28 01 is the five speed and M28 02 is the automatic.
Good luck,
Jim

When I bought the car I was told it was a 928. The seller never actually said it was an "S". I just thought I was getting a good deal. I would just like to know one way or another. Is the code on the plate with the VIN?

The engine code is on the front of your engine near the thermostat housing and is easy to see if you stand dead center in front of your car, pop the hood, and look straight down at the front of your engine.

Well thank you to all. I really appreciate all of your help. The car seems to have the 4.5l engine, but I don't care. I just love having a Porsche.

Go with the Mobil-1 15-50
It's the best oil you can use. I talked to a Mobil engineer a while back, and he recommends it for the 928 even in Cleveland where it gets real cold.
Here's why. The Mobil-1 15-50 synthetic flows down to minus 60 degrees. That's far better than you'll find in a regular 15 weight oil, so it allows easy driving in cold weather, great startup protection, and great viscosity when hot too. Nothing better. Far better than the Castrol 20-50 I used to use in everything I owned.
Now if you have a leak with regular oil, or a drip on the pavement, you'll see a bit more with the Mobil-1 simply because it flows so much better. It will find a leak and flow out the leak faster than regular oil. But if you have a tight car, like most 928 and 944's, then go with the synthetic. The Germans DID find out how to put two pieces of metal together and keep oil in, but the Brittish never discovered the secret.
