Roger about clean diesels. The pollutant that matters if you don’t live in a big urban area (98% of my Unimog driving is outside big cities, and 100% of my BMW X5/35d driving is around a quite small city with unpolluted air except for volcanic eruptions and forest fires) is, of course, CO2.
And no ICE engine emits less CO2 than an electronically controlled diesel without DPF, and preferably without EGR (reduces black carbon emissions compared to +EGR; black carbon reduces albedo of Greenland ice sheet).
Anyways, I got D1SHC 5W40 from my local Anchorage Mobil lube distributor. No added cost for shipping. It’s sold in USA mainly to inland shipping users, like Mississippi basin river barges, for mains or auxiliaries.
A caution or two. My last batch was $38/US gallon. I don’t pay attention to posts bragging about getting something at Walmart on close-out for $0.50/qt. Yes an oil change costs $281 in oil. Don’t care, if I can literally drive around planet on it.
And it has sulfated ash = 1.9%. Pre 2007 Mercedes diesels are fine with that, it’s the only MB228.5 5W40 I could source in North America. But most American pre 2007 diesels call for 1.5% or less. And lastly, certain common American diesels (all the Fords with HEUI for example, like later 7.3, 6.0, 6.4, and deleted 6.7s) need ultra short OCI due to shearing by the HEUI injectors.
My engine (OM906LA) has an early VW-like PLD camshaft/pushrod powered, electronically actuated unit injector system. Unlike VW doesn’t eat cam lobes, has roller lifters for injectors but simple solid lifters for 2 intakes (1 pushrod with bridge) and 1 exhaust. Standard Jake like exhaust brake 4th valve (but QUIET) pneumatic actuated.
So don’t use it unless 1.9% ash OK.
If you want 1.5% ash oil with high TBN and good Zn/P there’s 3 North American boutique brands I can recommend.
Not for oil cheapskates.
