First Oil Change 2021 Ram 1500 Big Horn Crew Cab 5.7L

I'm honestly afraid to go with aftermarket oil filters while still under warranty, especially if I'm DIY myself. I don't want to give them any ammo in case there is an issue.

Once my 5 year powertrain warranty wears out, I'm going aftermarket!

As long as you keep the receipts to prove you bought the products at the right time and you use a quality product you will be okay. There's even a place for you to enter maintenance data into your mopar.com account for your truck.

I've got the 7 year / unlimited miles Max Care ESP and have been doing my own oil changes since I bought my truck (Mobil 1 oil filter and Pennzoil Ultra Platinum oil).

Are you sure you weren't just viewing the cartridge style oil filter that the V6 uses?

68507598AA, 68498720AA are filters for the 3.0L EcoD engine.
4892339AA, 4892339AB, 4892339BA, 4892339BB are all filters for the 5.7L Hemi.
68191349AA, 68191349AB, 68191349AC are all filters for the 3.6L Pentastar.

The "AA", "AB", etc. are just different part revisions. The further in the alphabet those last two characters are, the newer the part design/revision. I'd recommend you purchase the latest part revision possible for a part number, as a general rule of thumb, but it may not be necessary. Sometimes, some filter part #s are only available in large packs or other packaging, and there may not actually be a difference in their design.

EDIT: There are also other part numbers out there that are sometimes used, such as MO339 (MO-339). This is more of a "model number" and can be used to describe multiple revisions of the same filter. E.g. MO-339 can mean 4892339AA, 4892339AB, 4892339BA, or 4892339BB.

Thank You this explains it completely. Back to Walmart for the Mopar filter.

I don't claim any knowledge to how the oil life meter works but the truck tracks idle time too. It is a setting in the cluster. Only other vehicle I had that did that was a P71 Crown Vic.

The PCM software is programmed to always give you the 500 mile "Change Oil" message before the odometer reaches 10,000 miles. But the odometer is not the primary source for triggering the message. The PCM has a message set driver called 'engrevcount' so it is counting engine revolutions. I can tell you that my two previous 4th gens had the 3.92 axle and I always saw the oil change warning appear well before 9500 miles. And it varied between 8800 and 9400 miles. My 5th gen with the 3.21 axle (edited) always has gone to 9500 miles before the 'change oil' warning message appears.

Best regards,
