Various Virgin Oil Analysis...

[BOBISTHEOILGUY]

I have to agree with Dragboat. Widman, there is no value in posting those numbers since it has no meaning of what oils we are discussing. If you have a virgin oil analysis on the Delo, and that is the only one you feel comfortable posting, go ahead and post it in a new thread so others can find it easy.

I wonder if the SL formulation of 15w40 Pennzoil still has moly? Can you find out for us
Johnny?

There are some very sensitive people here who will argue that no one has a right to mention their names. I've had letters from their lawyers, although mine says it is not a crime to educate. I copied a slide from a presentation where I stay away from brand names for that reason. The second column is "American" (my group I - made in Tulsa). The rest I had to look up at the office.
In order they are:
1. Chevron Delo 400 15w40 (USA)
2. American Supreme 15w40 (USA)
3. ESSO XT3 15w40 (Argentina)
4. Pennzoil Long-Life 15w40 (Bolivia)
5. YPFB Diesel Premium 15w40 (Bolivia)
6. PVD 15w40 (Venezuela)
7. Shell Rotella 15w40 (Argentina)
8. Shell Rotella 15w40 (Argentina)
9. Venoco 15w40 (Venezuela)
--The two Shell samples were from two identical drums at the same site at the same time.
NO Moly in any sample.

I use the slide to try to get people to read the label, program their maintenance by analysis of oil, vibration, temperature, etc. and figure out who you can trust. I had also taken the names off so people in the audience wouldn't get hung up on a discussion defending their favorite brand, especially since the 5th sample (the worst) has a 60% market share because everyone's father taught him it is the best (15 years ago it was the ONLY oil sold legally).

I, too am interested. As I said above, they went down on the zinc considerably with the SL formula which makes me believe that they still have moly. I can't see them going down on the zinc and not keeping (or increasing) some other type of barrier ingredient.

Problem is, if the barrier ingredient is an ester, you'll never know since used oil analysis does not detect these fluids.

Was this the old green GT 20W-50 or the new melow yellow version?
