Re: Delo 15-40 VS Rotella 15-40
One of the reasons I prefer Delo 400 over Rotella in a modified 7.3L is it's additive package. Delo 400 uses Moylbdenum like Schaeffer's does - just in a smaller amount. Here are two oil analysis reports to show my point. The first is a virgin oil sample of Rotella 15W-40. The second is of Delo 400 15W-40. Looking at the additive levels on the reports, you can see the difference in the additive packages.
Unfortunately the Delo 400 report I posted is not of a virgin sample but I think it will sufice to show my point - even though the additive levels are lower than a virgin sample. I thought I had a Delo 400 virgin sample on my laptop at home, it must be on the work one.
