Honest I am not trying to be a But there may be a couple of other options, I do believe that the VW51100 spec will also show C40 on the container and therefore should be fine to use, Audi and VW dealers may have 0W-40 in stock.

 

The REQUIREMENT is C40-spec'd oil; the C40 spec includes both 0W-40 and 5W40 oils.. I've managed to find FIFTY-EIGHT quarts of Mobil 1 ESP X3, not that I intended to have that many.

 

Actually according to the manual it is not only C40 but also VW 511 00, both are approved as shown. The recommended SAE Viscosity has been changed since the 2020 models arrived.

58 quarts, now we know why there is nothing on the shelf!

BTW no need to shout...

 

I knew Audi had a C40 0W40 oil (re-branded Mobil 1, afaik), but was out of stock last I checked.

I didn't know about VW. That is closer to my house - thanks.

Since many Porsche dealerships share dealership space with Audi and/or VW and yet have been forced to use A40 oil when they service cars, I suppose it must be because those oils are out of stock as well as the Mobil 1 that Porsche sells. Or Porsche decided it was a bad look to use Audi or VW oil...

 

Your local Audi dealer has the approved 0w40 oil. It is Audi Part # G-E55-040-1Q-DSP - C40/VW511 certified. It's cheap (sub $10/qt), And I'm 99% sure its actually just rebranded Mobil1 ESPx3 0W-40.

Can be ordered online too. Google the Audi part number.

 

I use all-caps to emphasize the point I'm trying to make; I use bold because it's easier for me to read.

 

Bold text and all caps is considered yelling…universally.

Alternatively, you can adjust you device font and size for your ease of reading.

Also believe 2022 and above dropped the 5W-40 from the C40 recommendation.

 

Stopped by my local auto parts store today, and they have the other “non X3” M1 ESP 0w40. Looked a bit like older M1 bottles. I checked online at Mobil website and looks like these 2 versions have different chemical properties.

^^^ Only the ESP X3 Mobil version of the 0w40 (and its audi-branded twin) are C40/VW511 certified.

 

THE BOLD WASN'T ENOUGH FOR YOU?

 

Got 10 quarts today from AutoZone, as some have pointed out. Thanks!

 

I just stopped by my local dealer to buy some oil as break in ate about 2/3rds of my oil. I let them tell me what oil I should get. Parts girl didn't know off the top of her head, looked it up and gave me a bottle of C40. Then said it was on the house. So +1 for them.

 

Is it even a car forum if there isn't an oil thread?

 

So, I have 6,000 miles on my car and have added a quart already, and the gauge is below midway, so I bit the bullet and ordered 4 liters from Porsche at $20 a pop...not the best solution, but I cannot find C40 anywhere and I don't have time to go running around any more than I have already to find it, unfortunately. Local auto store chains had nothing...just 0-30W and European Formula types, but nothing that was labeled C40. This will give me peace of mind and a hole in my wallet

 

When my car was at about 6000 miles, I was going back and forth with red and yellow on the car and this was while I was traveling at Werks Reunion lat year. Popped into Porsche Monterey and they were kind enough to add a little bit of oil in my car free of charge to at least get me home so it wasn't in the red. Got home and paid for an oil service. Figured, if it's low might as well do an oil service and took the opportunity to do an alignment too.

Fast forward to a couple of weeks ago and I did the free 1 year service. When I was done and about to leave go to chatting with my advisor about oil consumption and as I was getting up to leave, he gave me a quart on the house. Not saying every service advisor will give out free oil but if you're low, try popping into your local dealer and ask them to add a little bit.

Both instances, the service advisors were very nice about it.
