Delo 400 5W-40 Syn

[321]

any one have thoughts on this oil?? I have used delo 15w40 and the chevron Supreme synthetic in the past with good results.

Can some one decipher the Phosphorus and Zinc amounts.

Can we assume that there was a 30 grade right next to it in the PDS??

This is a CI-4 rated heavy duty engine oil, typically used wherever you desire higher zinc and phosphorus levels. You would normally see this being used in diesel engines, but many gas engines are using it because people are looking for the elevated levels of zinc and phos either because they have a higher mileage engine or the have a flat tappet design engine. You may not have run across the term "flat tappet" before. If not do a search on here or even with Google and you'll see why people look specifically this oil.

There was a used oil analysis for this oil posted within the past week on this board so you might look for it too. The only problem I see with this oil is that its sometimes hard to find. If the viscosity is right for what you need, then I'd run with it.

Yes, the Delo400 0w-30

I would be one of those people. I have a 02 Discovery with a old Buick designed engine flat tappet inline cam.

Phosphorus, wt % 0.136 = 1360 ppm
Zinc, wt % 0.151 = 1510 ppm

An excellent group III synthetic, I've done UOA on it in the past, and have it in my 88 BMW, changing once a year. I doubt that I will analyze it this year since I run 30% or so aviation gas with regular. That means I will have lead in it that is not coming from the bearings.
One of the ones I recommend for flat tappet engines in my report, although in the cold it actually flows like the Amsoil 10W-40 AMO.

Thank you for the Numbers.
