Why are you using the hot shot stuff?
Amsoil is a high detergent oil, and our injectors don't have oil in them like the older power strokes.
I thought you had a 5.9? Why CJ oil?
You do know our turbo's run on oil and the Hot Shot stiction eliminator will clean the turbo of any deposits from 145+ miles of use. Just one more thing to help keep her in tip top shape.
I was not aware that the injectors in the 03 and up Rams were not lubricated. Would think with the very high pressures these injectors see they would have some kind of lubrication for them.
The CJ-4 Amsoil is backwards compatible with older vehicles and is the only oil offering a 25,000 mile or 12 year warranty when used with their oil filter.

Yes the turbo's run oil, but stuff like that alters the properties of the main oil and it's not something I would want in my oil if the motor is ever worked. The Amsoil has a great detergent package. Amsoil will not warranty the oil if you put an additive in it. The warranty is hard to do anything with anyhow, I never made the 25K miles (back when that was the rating) based on soot and even as a dealer I couldn't get anything warranty out of them.
Dodge has never used injectors with engine oil, that is a Ford injector thing in pickups.
Where do you see a 25K mile warranty? Both oils appear to be rated for up to 50K miles/600 hours, or 1 year in pre-2007 engines, not to exceed 3x the OEM interval. Since you are on this site I will assume you are Schedule B, as 99% of owners are, and that means up to 22.5K miles. There isn't a single diesel oil on their 25K miles web page. http://www.amsoil.com/shop/by-category/25000-mile-oil-change/

I would use UOA for drain intervals past 10K miles, based on UOA experience with Amsoil and my sig truck. I'm a dealer, and believe in their stuff but have found the oil isn't quite as long lived as they claim in multiple rigs with multiple different oils. Each rig and use does different things to oil.
CJ is backwards compatible, but I haven't found many people (including multiple tech's at Amsoil) who claim it is better than CI oil, if the motor is spec'd for CI oil.
The AME has a higher TBN, so it will generally last longer and has a higher ZDDP level so it's better for flat tappet motors like the Cummins. The CJ oil will work, but if your going to buy Amsoil you may as well get the better oil at a lower cost. The CJ wont increase wear, just isn't as good as CI was. CJ was developed for emissions, it had to be changed significantly to meet DPF exhaust criteria.
