C40 Oil Discussion

I just stopped by my dealer and found out some interesting info. They said that them and Porsche both know about it, but they've had the oil on backorder for three months now. I then of course asked about current oil changes for customer cars and was told they have no choice but to do them with the old A40 spec. They are documenting everything for CYA purposes and the potential issues down the road.

if Mobil1 c40 isn’t available they should actively be exploring alternative c40 sources instead of putting Mobil1 a40 in. Alleviates the mixing concern. I expect better. Their response may hold some weight for warranty work but what about long term impacts of this ho-hum approach?

I just did a Google search for "Liqui Moly Top Tec 4110" and found that FCP Euro sells it for $34.99/jug, free shipping with two ordered.

So $70 for 10 liters which is enough for an oil change with enough to spare for top-up. Not Mobil 1 but not $20+/liter either. And it meets all the specs.

I just now checked Summit racing's site and they have Mobil 1 0W-40 ESP oil for $12/ quart. It claims to be formulated for gas particulate filters, and is dexos 2 rated. No idea if it is C40 approved, couldn't tell from the description.

Edit: Just looked at their page and I'm 99.99% sure it is the A40 spec.

Similar issue when GM changed formulation; dealers were clueless and stock was lacking. Don’t believe it is C40 certified. Dexos is GMs cert.

Tough when all of the information is not provided, we can't even be sure that included pictures are correct, but if they are then the UPC indicates it is NOT the X3 version, and the back label does not show C40 either...

I just picked up my Spyder from its 10,000 mile / 6 month servicing. The dealer used Mobil 1 A40 for the oil change. I'm still waiting for them to tell me why they didn't use C40, and what should be done about it.

This is what I'm going to be using...
5W-40, C40
DIY project with my son planned for the XMAS break (there's %$#@ nothing else to do up here, everything is closed...)
Is there a tread with pics for oil change somewhere?
Otherwise, I may take pics I do one myself for the benefit of others

There are lots of YouTube videos of oil change, probably none of the new 4.0 718's but most things are similar. Oil plug is plastic and removes with a screwdriver. You're supposed to replace it but I've read where some reuse it with no problem. There are apparently some under body panels to remove to access it, but I've been doing that on my Cayenne for years.
