Lubro Moly 5W-40, 4k, VW 1.8T

[Steve_RI]

This is my first interval with a new oil after using Amsoil 5W-30 (SAE) since the 5,000 mile mark. It doesn't haven't any moly, but the #'s look pretty good.

Very low wear metals, nice! I don't know much about this oil, is it a PAO base?

Yes, this is the PAO based oil.

Steve,

What was the baseline viscosity of this oil @ 100C? I'd suspect it was 14.0-14.5 ....

This engine also seems to rapidly degrade the oil - perhaps this is why VW recommends 5000 mile oil change intervals. The high nitration and low TBN remind me of the Camry V-6 ....

The wear numbers are outstanding ....

see Virgin Analysis sample info...

I've seen a couple VW 1.8T UOA's recently and I figured I'd bump this up since I didn't specify a 1.8T in the original post. Nice to see more analysis showing up on this motor.

I edited your title for you.

Actually, starting with 2001 model year, the oil change interval has been increased to 10,000 miles (at least in Audis with the same engine). A bit long, IMO, especially if it's not all just leisurely highway driving. The analysis I posted after 5K miles of mostly city driving showed that the M1 SS 5w-30 that was in there was almost ready to get changed. However, these Lubro Moly wear results from Steve_RI look a bit better than mine. Perhaps I'm a bit harder on the engine. Or perhaps Lubro Moly is a better oil.

So, Lubro Moly has no moly?

 

[Patman]

Maybe Lubro means NO in some other language?

LOL. Why didn't I think of that.

Lubro-Moly offers several oils.

Voll-Synthese Energy Motoroil 0/40 that is a specialty in-house product of Liquimoly of Germany

Voll-Synthese Fully Synthetic 5/40 and MOS2 Antifriction Super Motor Oil 10/40 they claim has the right amount of MoS2 for optimum wear protection and friction reduction. They state this oil is a hydrocracked base.

The other two does not say what base or if it has Mo or not. FWIW the 0/40 is the most expensive then the 5/40 and the 10/40 comes in the lesser cost oil. It's in TX,CA,and New Hampshire as far a availability is concerned,,probably more sources than that.
