Find a Mobil distributor and ask. Where do you live? I have purchased relatively retail quantities the 2 times I bought it. But the SHC isn’t good for a US mfg engine; new stuff “Ultimate Defense” is ok((CI4+ etc)

Are you kidding? I had to have local Mobil distributor order the SHC in 2007 and again maybe in 2017. Apparently it’s used in the States on Mississippi River tow boats. So it took weeks to arrive. In 5 gallon jugs.

Ash levels 1.4-1.9% used to be pretty standard for ACEA E4/228.5 oils. I guess Mobil’s latest version is Delvac Ultra 5W40 Ultimate Defense. It’s only 1.2% ash, TBN about 14.5. I’ve got enough SHC in the basement to last the rest of my life. It’s convenient to just carry makeup oil on a very...

Absolutely yes. With no EGR, up to 1200 hour/40k miles oil change interval. Although most with same engine in North America (mostly Freightliner medium trucks) use 228.3 or nowadays 228.31/32 and probably (should) do shorter intervals, maybe 15-20k miles. The 906 is much friendlier to oil...

TBN 11.5 after 25200 miles VOA TBN 16 Fe 44ppm Ca ~4450ppm Zn/P 1405/1387 Vehicle = 2005 Unimog U500, EGR deleted, OM906LA motor (6.4L) Oil = Delvac 1 SHC 5W40 Sorry, never have been able to post files on this site

Initial TBN supposedly 16. Second one is after 1000s of miles of Russia 300ppm fuel, also some Mongolia 3000ppm. 25000 miles. About 10L makeup in 30L sump.

I agree with the posts “if you are still on warranty don’t do this…” However: Redline Break-in Additive had Zn 20500ppm, P 17000ppm, Ca (as detergent) 20000ppm on a VOA. Be cognizant that since it’s labeled and sold as break-in additive, the ZDDP is likely alkyl rather than aryl. And I don’t...

It might be helpful to know a bit more specifics about the application. Like is this a line haul or vocational tractor or farm tractor; or a toy sled puller or toy souped up farm tractor; is it going to be used in Canada where GCWs can be quite a bit over 80k lb but winter temperatures colder...

I wouldn’t recommend running this oil in Mongolia (3000ppm S) or even Russia (300ppm, though 10ppm sometimes available). Or any of a list of countries in Africa, Asia, or South and Mesoamerica with sulfur up to 5-10000ppm in the fuel. TBN isn’t measured by the presence of any particular...

If that’s true I am glad I have a decade’s worth LE and SHC 5W40.

Yes Doug, it is available in the US now. I use with great UOA results in my 09 BMW X5 35d which is is “emission system deficient”. Even before the “surgery”, the factory recommended C3 based oil (?LL08?) did very poorly as far as TBN and wear metals, due to NOx acidification in turn due to EGR.

It’s impossible to find a PDS on their site. 2.9 strikes against them. If I were looking for a boutique 15W40, including especially a CI4+ “legacy oil”, I’d use TRC (Texas Refinery Corp) products. Not the least because they make their product specs easy to find.

There’s several boutique mfgs of what look like really good CI4+ 15W40s. Blue Ram in Canada, Texas Refinery Corp (TRC), and at least 2 others that I’ve run into. I can still order Mobil Delvac 1 SHC 5W40 from my local distributor with TBN 16, ash 1.9%, 1400ppm Zn, 1280 P. But not CI4+, it’s...

Find an oil high in esters, which tend to cause seals to swell slightly. Redline used a lot of esters. And so does Penrite in some of their products. Personal experience with the effect with Penrite Syn 75W90 gear oil.

With some difficulty I found a PDS that included TBN: 8.6. I was thinking about its’ usefulness for Canadians or northern tier USA states that make an annual trek to Mexico every winter; considering much Mexican diesel is still ~300 ppm.
