I use nothing but Delo400 10w-30 in my diesel application on a golf course vehicles(all deisel engines). I'd slip in some Chevron 10w-30 in diesel cushman but conditions are different from Mowers that see alot of dust and grass clippings. I did ok but the Delo seems like a better stable oil in extreme conditions but conditions are different with gasoline engines. I'd slip in the Chevron in cushmans and see no difference from manual oil OCI from Delo400 but perfer the Delo400 in extreme dusty conditions.
Delo400 has no Moly but in certain driving conditions Moly is not necessary as Penzoil has change it's formulation with no Moly. There tend to be more combution by products in higher mileage engines and see a good reason to extend your engine's longivity with using Delo400 as I've used it other high mileage vehicles as a cushions. What's a few cents more for added protection.

The Delo will need to be around a 12 cSt to be rated. The Rotella 10w-30 I use is that visc, and I believe the standard is based on HT/HS. Chevron Supreme is what, about 10 cSt?
I read this on the Chevron site and can't remember reading this before about the new Delo.Delo 400 continues to use ISOSYNTM technology, which provides equal or better extended drain capability and fuel economy as synthetic oils, but at a much lower cost. Although Gene posted Delo as a extended drain oil back then now the company came out and posted it.
