RustyJC said:I'm not going to get in the middle of an oil war, but I am going to suggest that if your warranty means anything to you, you need to check out API certification of whatever oil goes into your engine as well as DaimlerChrysler's stand on extended drain intervals.

I also use a bypass filter set up the BMK-15. But it was a real " B" putting it on. Check with Amsoilman as he is a dealer in that neck of the woods.![]()

If your $12k Cummins engine has a major problem and Dodge denies your warrantee because you are not using API certified oil will Amsoil replace the oil under warrantee :-laf
Not worth the risk in my opinion, stick with good regular dino oil at regular change intervals and you will never have a problem that is oil related.

W. A. Derby said:Why don't you go read their warranty before making fun of it. You come off as rather ignorant that way and I'm sure you are not. Oh I forgot your from MA & know everything, including not needing winter fronts where you only visit & do not live. Amsoil will repair or replace any mechanical item that fails due to their oils/lubricants/filters etc. Know what you are talking about before you open you mouth and criticize something. If you paid $12K for your Cummins, you got ripped off. They are $5K around here. Oh yes being from MA you have pretty much the same air quality regulations as CA? I guess that is what the extra $7K goes for. My mistake.
BHolm said:Gee, thats funny, since when is Amsoil not API certified? The brochure in front of me lists the series 3000 HDD oil as API CI-4+ rated AND Cummins approved.
I would also like to hear from somebody that has had an oil related failure on a Cummins period. How likely is that... . like a million to one... and you would have to have some non certified strain of Amsoil in the truck too :-laf
I have Amsoil in my '06 as of the other day, along with the Donaldson extended life oil filter. I will run 10k intervals like this and there is NO WAY DC would ever not cover my engine. I only change half as often as I would on Rotella, so it costs the same and half the messAfter I switched on my '05, along with Amsoil diff fluids and t-case fluid I picked up 1-2 mpg. I am expecting the same with this truck.
If an engine oil has the API donut, it is certified by the API to meet the qualifications for the service classifications listed. If it doesn't have the API donut, it is not API certified.Bertram65 said:Is Amsoil API certified?
