Delvac 1 Wear Rates?

[The_Oz]

Anybody got any data on the wear rates of Delvac 1 and using what test? Maybe Terry can answer this question...

Thanks,

Oz

Delvac 1 is an excellent oil. Assume you're talking here about 5W40.

What specifically are you looking for:

Wear metal in mg/hour,
Four-Ball wear tests,
V-Block Wear Tests?

I have some wear (bench testing) data on the 5W40, and maybe the 15W40.

MolaKule, AWESOME!!! Please post them all! Yes, I am referring to Delvac 1 5W40 Synthetic. I was more curious about the 4-ball wear test and then compare it to AMSOIL and Schaeffer (if one exists). But if you have more, then that's great too!

Thanks,

Oz

To the top for more info! This oil seems amazing!

Does it uses any metallic adds?

Theres a post on the TDI forum about D1 wear rates. I think it was cam wear rate and something like .001 in 30,000 miles dropped to .0002 in 130,000 miles using D1.

sprintman -> Thanks, I'll do a search in TDIClub.com and take a look. However, MolaKule's numbers might prove a bit useful as I can compare them to, let's say, AMSOIL.

TDI on Mobil D1 by Troy_Heagy. I'm not sure what you mean by metallic additives. But hopefully the Troy_Heagy analysis will answer your question.

Oz, here is what I have (A slightly older formulation of Delvac 1, 5W40; I assume the numbers are somehwat better now since they have had time to tweak it since this test was done):

CAT 1M-PC
Ring Side Clearance - Loss mm - 0.012
Piston, ring, and liner scuffing - 0
Piston Ring sticking - 0

CRC-L-38 (3X, 120 hr)
Bearing Wt. Loss, mg - 20 mg

Extended 128 hr. Seq. IIIE
Cam and Lifter Wear - um, 5.2

In Gas Engine, 50,000 miles accumulated, 25,000 mile Oil Drain Interval, 2.0L, I4;

Oil Cons. averaged 6,000 miles/qt
Oil Vis. Increase@40 C - 15%
Used Oil TB - 8.4
Emissions in Gas Engine for above:
HC - 0.2
CO - 1.85
NOx - 0.60
