2012 Touareg TDI - Which oil would you use?

[RooflessVW]

Another one, I know. The details:

My 2012 Touareg TDI (3.0 CATA V6) will cross 130,000 miles tomorrow and I'm doing an oil and filter change. I have been doing oil only every 5k and oil + filter every 10k.

I have a Mann 8001x ready to go but also several choices of oil. On hand, I have:

Carquest 5W-40 dexos2
Carquest 5W-40 HDEO CK-4
Rotella T6 0W-40 CK-4

The dexos2 oil is probably the most suitable, but I don't really see the harm in running an HDEO. This engine consumes no oil and has no leaks or other mechanical problems.

I would run the Rotella personally. No evidence of superiority but I've always used it, and know many people who have as well. Someone with knowledge of specs and certs will be along soon!!

2012 is pre emissions right?

2012 is pre emissions right?

Negative. EGR, DPF, SCR, DEF all intact. SCR was replaced ~ 4,000 miles ago. The rest is original.

I always like T6 but you know best.
This is your game.

Any of those would be fine. See no reason why the engine would be upset with it.

 

[UG_Passat]

HDEO may have a SAPS of 1.0 ppm

vw 507 limit is 0.8 ppm

 

[RooflessVW]

vw 507 limit is 0.8 ppm

dexos2 as well.

CK-4 limit is ≤1.0

 

[bluesmokertdi]

you want a low ash oil, VW 507,

a CK oil may lead to DPF failure

the oils would protect the engine yes, but the ash may kill the very expensive emission control systems

I'm aware. Been running 504/507 since 80,000 miles. Warranty is up and I am not buying more spec oil when I have plenty of "other" diesel oils.

Maybe. Maybe not. A full DPF does not really concern me.

If a clogged DPF isn’t an issue, I’d run a HDEO like T6 for sure. This should be a good experiment.

I mean if it fills up, I'll just "deal with it."

 

[Jetronic]

it won't fill it up, 1.0% of nothing is the same as 0.8% of nothing...

We're of the same mind here, friend.

Love that engine and the endless torque. I'd run the T6 personally.

I'd consider running PP Euro L instead. At least it carries MB and BMW approvals for modern diesels, along with ACEA C3.

And a 5L jug costs $25 at Wal-Mart; not sure you'll find a better oil for $5/qt.

If I wanted to buy more oil I'd just buy more M1 ESP.

T6 IMO. From what I have seen around GTL+some PAO.

I believe the VW approval limit is 1.5%, it is the accompanying ACEA C3 that drives it to 0.8%.
