Can't figure out how to post pdfs, so here are the links to Chevron's and Shell's data sheets: Delo 400 SDE (new formulation, lower Zn an P, ashless additives): https://cglapps.chevron.com/msdspds/PDSDetailPage.aspx?docDataId=481951&docFormat=PDF Delo 400 LE (old formulation, no longer...

Oops. Looks like I need help posting the pdfs?

Here's the Shell Rotella data sheet for 15w40 And the response I got from Shell: Quote: For the flat tappets, I’d use the Rotella as it does have more zinc/phosphorus than gasoline engine oils. The Zinc is 1200 ppm for most grades including Rotella T4 15W-40. As for the numbers you’ve...

I'm having a Ford FE engine built, and the builder strongly recommends hydraulic flat tappets for the best reliability. He's had good success with Honda Motorcycle Oil (GN4), which, from my research has less that the desired 1200 ppm zinc and 1000 ppm phosphorous. Two oils that have...

By the way the Honda GN4 is less than half the price of Valvoline VR4, which seems to go for $50/6 bottles. Kinda surprising as I'd expect private label oil to be more expensive.
