Does anyone have experience with Amsoil Series 3000 5W-30 HDD CH-4 oil in a diesel? "PRODUCT DESCRIPTION AMSOIL Series 3000 Synthetic 5W-30 Heavy-Duty Diesel Oil is a premium quality all fleet lubricant, specifically designed for use in commercial, industrial and fleet applications requiring diesel specifications CF, CF-2, CG-4, and CH-4 and API SH, SJ gasoline engine lubrication requirements." http://www.amsoil.com/products/hdd.html I'm not proposing it--I'll stick with Delvac 1--but Amsoil does push it for diesels. I'm just curious if anyone here has had experience with this oil in a diesel. Ken

Since I don't have a diesel, I don't have personal experience. I do, however, have quite a few customers who are using it in their diesels. They are very pleased--and oil analysis has shown it holds up very well. Just an aside--the owner of AMSOIL runs the 5W-30 HDD in his own (gas) engines!

D'ya mean Smilin' Al? Did you know that he also owns Oil Analyzers, Inc.? Will their analysis be completely objective? Ken

I used the 5W30 HDD in three gas vehicles for winter use. Never did any analysis but never saw any problems associated with it either. I also use it in my back-up power generator for the winter. Its a 10 HP Tecumseh and you won't hear any piston slap or other internal noises with this stuff. If it had an electric starter, I'd probably have used a 10W30, but since its a pull-type (recoil) starter, I prefer the 5W30 HDD. Ken, OAI has shown to be an accurate analysis company with a penchant for having expertise in the analysis of synthetic fluids. I am changing to Terry Dyson's group, however, since I would prefer a company that has no affiliation with any oil company.

Ken, See my analysis numbers on this oil in a Cummins Engine in the Oil Analysis Reports section of this forum.
