EcoDiesel UOA (Oil Analysis) Results Thread

[biodiesel]

I was going to switch the the Amsoil that you have on the top shelf in the photo but on there website it says it does not fit my vehicle. Am I missing something? Just want to be safe.

Amsoil MS doesn't have the MS-12991 Chrysler approval, but that's not a concern unless you're worried about warranty. In short, Chrysler has a contract with Shell, so they only recommend oils from Shell's lineup (Pennzoil, Quaker State, Rotella, etc.). Unfortunately, Pennzoil Euro was the best they offered for the 3rd gen EcoDiesel. But in all honesty, the Amsoil Euro MS is a better oil for both emissions and for engine protection.

We also have guys testing Amsoil Signature Series. So far, that performs even better than Amsoil MS. We just need to make sure that Amsoil Signature Series isn't leaving deposits in the turbo. So, we have a few guys using a borescope to examine the turbo once they get some miles on it.

Thanks so much! I'll go with the amsoil euro for now and move over to the signature series if you're testing shows that it's better!

Yes, that would be my preference as well. That way everything in my current fleet (2015 Ram EcoDiesel, 2020 Ram EcoDiesel, and 2023 Gladiator EcoDiesel) would use the same oil. That would simplify my engine oil inventory.

I switched to the Amsoil MS. In testing, my results are better.

what tune are you running again?

No tune. I had a Banks Derringer.

Should I be concerned with a tune then. Looking to switch to the Amsoil MS. I will have the EOC tune, tow with EGR turned off.

The 5,800 miles on this oil included a trip towing a small travel trailer about 1,300 miles with temperatures from the 90s to a little over 100 degrees. I screwed up and didn't catch enought for a fuel test. This was my second test on 5w-40 Amsoil MS collected while changing.
