My new Porsche has the ea839 engine which I believe calls for 508 or C2 oil. It's near impossible to find the correct spec and I don't have the manual in hand yet.

So the question. I'm still a little afraid of 20w oil in some applications. This is a 4500lb SUV with a turbo v6.

If I was to say I am not worried about warranty implications, what spec would be best for this engine? A40? C30?

Most trips will be 30 miles one way in mixed driving/traffic. Slight heavy foot driver. I hate the way my wife drives, it makes me sea sick 😁

Audi forums are saying the new 508 oil has a dye added and it is checked if there is a warranty claim. Don't know that as a fact....just saying. Anyway, I use the new 508 oil in my 2019 Passat. Granted it is a four cylinder but I am using no oil, it is staying clear (I know, not a UOA) but so far no complaints.

The ea839 engine does specify 508.00/509.00 oil. That V-6 shouldn’t be to hard on oil. I can’t tell you what you should use. Castrol does make their Professional OE LL 3 oil, that is 5W30 504/507 and has the same dye in it as the LL IV.

C30 should be OK. (A40 has too much SA which some say could create more valve stem deposits on the DI engine.) In VW 2.0L turbos that spec 508 0w20, VW has been telling dealerships of possible problems if non-508-non-0w20 is used. Seems strange to me. C30 Mobil1 ESP 5w30 maybe.

Should you decide to have faith in Porsche-VW-Audi recommendations for 508, then suncoastparts.com right there in your local FL swampland, or ecstuning.com or rmeuropean.com will ship to you if your own Porsche dealer jacks the price up.

The 508 spec forces oil makers to put in zirconium chemical markers so Porsche would know you're not using the "right" oil. And its green-blue (teal or similar) to try to get technicians to use the right oil.

I wouldn't worry a second about using a xw20 oil. The engine as far as I can tell uses liquid cooled turbo bearings with wide main and rod mountings/caps with a demand controlled variable displacement oil pump. You could say the engine was designed around lower viscosity oil unlike many engines that could run almost anything and just back spec'd for CAFE reasons.
Personally I would not run a heavier oil in this if it calls for C20/508.00, the pump and the engine were not designed for it. This oil looks like it will fit the bill for that spec and includes the dye. Castrol is good stuff.

Edit: This is interesting.

Trav is right.
Take a look at page 7 of https://drive.google.com/file/d/1GruL4CARAbo_0WL8zUZc5usiiT1IXD7M/view where they say cylinder wall temperature was dropped 20C, which would help the use of lower viscosity oil smeared on there.
The French ship us the cheapest C20 508 oil. rmeuropean.com Total 0w-20. https://www.rmeuropean.com/Products/206764-MFG759.aspx

Thanks for posting that. There is some serious technology in that engine, they state C20 or 504.00 as the oil spec. I guess he will have to wait and see what the owners manual spec is.

They mention 0w-20 on page 26 of https://drive.google.com/file/d/1GruL4CARAbo_0WL8zUZc5usiiT1IXD7M/view and the mention of 504 is a typo probably, should be "508".

If manual states also 504.00, stick to that.

Beercan, run to your Cayenne glove compartment and pull out the Owner's Manual. Its not on the web. It says Porsche C20 like what the Audi EA839 engines use, right?
