The thing I don’t understand is I did a search on Amsoil for a 2020 Jeep Cherokee with the same engine I have in my Jeep Wrangler and and Amsoil says to use the Signature Series 5w-40 Diesel oil and when I look I’m my Jeep Amsoil doesn’t have an oil recommendation. It’s the same engine.
That Mobil1 5W40 TDT has as much Zinc as 15W50 for track.I'd use a CK-4 rated Diesel Oil in either a 5w40 or 15w40 depending on whether or not you need a lower cold starting viscosity.
So YES, you can use the Amsoil Diesel 5w40.
Here's the UOA's from my 2015 Ram 1500 EcoDiesel:
How many fingers do you have on your hands?Mobil1 ESP 5w30....
xW40 DPF friendly oils are like unicorns.....you can count them on fingers of one hand...and they CANT be in VW 504/507 since that spec is only in sae30.
Castrol magnatec C3 5w40....Castrol (have to look at the service papers of previous owner...dunno its flavour)...... Repsol elite 5w40....
Only 10...but you are reading post #16 here:How many fingers do you have on your hands?
. Also the Cam 2 oil listed says not for DPF filters .
DPF will not fail during warranty. FCA had big issues with bearings on that engine. ACEA A3 oils are band aid.So why does FCA say it is required? They want your DPF to fail?
