You can. But you can also just buy two jugs of 0w-40 and have some left over for top ups and for the next oil change.

So I guess no rotella then lol. So I still cant seem to decide. There's people here who say castrol and others who say Mobil 1. Why is it so difficult! Lol. Thanks guys for the awesome responses though! If I was to post this on an audi forum or something they would just yell at me and tell me to search. You guys actually help! I guess it's going to come down to whatever I decide to pick off the shelf lol. I believe that at Walmart Mobil one and castrol were honestly the same price. So it won't really matter too much I guess. I haven't really seen many or any of at all of the uoa's for the castrol oil though.

Because it's personal preference, that's why. Same reason why some like Coke and others like Pepsi. Both of the above oils meet the same stringent mfg specs, so from that standpoint, they are equivalent. Toss a coin if you have to.

The cheaper one else M1 if same price, mainly because Exxon/Mobil is a US company.

Like many said, M1 0W40 or GC 0W40. Both you can find in Wal Mart.
I used M1 0W40 with stellar UOA. Now using castrol 0W40 just for the sake of trying it. Once I am done with second OCI will do UOA so we can see how it did compare to my M1 UOA.

Personally, I would stay away from Rotella. Only reason why some people run it here is Lower SAPS content, but they drive DI engines.
I would say castrol would do better in cold. M1 does not have stellar cold cranking considering it is 0W40. Then however, it has HTHS of 3.8cp which is what really matters for Turbo application (Castrol is 3.7cp).

It's a European PDS. Not sure it's the exact same product as we get here, but quite possible.

Made in same place just sent to US and repacked into US bottles.

Has to be below 10% for MB229.5 claims

M1 or GC would be fine and I wouldn't use the heavier Rotella.
But if you want to try something new I'd suggest Pennzoil Platnium Euro LX 0W-30 discussed below:

There was once a thread on a forum with UOA history for a twin turbo Audi from about that era using M1 0W40. The oil performed very well.

LOL! I'm shocked!

Nope.

Just some expert sharing their incorrect wisdom with us. I guess fact checking isn't high up on the priority list.

T6 is SM as always.

I ran M1 0W-40 in my S4 2.7T for a 124,000 miles. Sold it with all mechanicals good and original Turbos huffing fine.

Cool story bro....

All manufacturer certifications are diesel. Yes it still has API SM. I guess in my mind, I like to see VAG, MB, BMW, etc. approvals.

Yes, but the API certification still includes SM, and that is, indeed, a certification. You stated certifications, and not builder approvals. Plenty of HDEOs have gasoline certifications, but don't seek gasoline engine builder approvals for obvious reasons. Shell has approved products already, and there is no point in cannibalizing their sales, not to mention that the diesel approvals include ACEA E specifications, not A and B (or C) specifications, upon which European passenger car specifications are based. Well, there is a point, actually, since M1 0w-40, for instance, can be found everywhere, whereas the Shell equivalent cannot, yet Rotella is everywhere.

Thank you Garak. Noob mistake, I didn't intentionally leave out the info.

Any reason for using M1 in a turbo Audi other than "I would use it"?

Mobil 1 0w40 has a long history of excellent UOAs and user feedback from a wide base of nearly every single VW, Audi, Skoda, Seat & Porsche aside from PD diesels.

Like I said, Shell Rotella T6 would also work fine (on the same basis of Mobil 1 0w40) but you'll need to top it up more frequently.

bobbydavro · Mar 31, 2015

PD diesels shouldnt use 0Ws. No 0Ws im aware of carry VW 505 01

Mobil 1 0w-40 vs German castrol 0w-40 vs rotella?
