Hmmmm, not really. Delo 400 and Delvac 1300 were his favorite conventional oils. I went though my mail archive and found these. *************************************** Quoting a message from Sun, 28 Aug 2005 10:50:14 -0400 You SHOULD be sure that the oil is suitable for a diesel. I recommend a CF or better rating and an xW-40 or xW-50 rating (CH-4 thru CI-4 rated oils are probably a bit more desirable, but that's hardly critical). The "x" should be some number between 0 and 15 (I don't know of a diesel rated 20X-xx oil but there MIGHT be one there somewhere). Most conventional diesel rated oils are 15W-40. In MY OPINION the best of these diesel 15W-40 oils are Chevron Delo 400 and Mobil Delvac 1300. The others commonly available in the US (Rotella, Exxon, Castrol, etc.) are inferior, rather ordinary, but can certainly provide suitable lubrication. Marshall *************************************** Then on Thu, 29 Sep 2005 14:40:00 -0400, in a thread about quieting noisy lifters on OM60x engines. Synthetic oils using group IV & V base stock (Mobil, Amsoil, Red Line) work best. Synthetics using group III base stocks (marketed as Rotella, Delo400, Valvoline, Pennzoil, Castrol Syntec) don't work as well (in MY experience) but they are superior to conventional oils (including the very best conventional oils - like Delo 400 and Delvac 1300). Marshall *************************************** Then on Tue, 13 Jun 2006 15:42:17 -0400 Lots of people LOVE it. It's cheap! It's also hydrocracked group III oil, far inferior to the group IV/V that Mobil and Amsoil sell. It's superior to the group II oils like Delo 400. It isn't nearly as good as M-1/D-1 for cold weather starting and it will NOT last nearly as long, but it lubricates pretty well. DOESN'T meet any of the Mercedes standard sheet specs!! Maybe Shell didn't submit it for testing, BUT their conventional group I Rotella and their synthetic Helix oils were submitted and approved for various service!
