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!
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):
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
