Hi, I have a 2026 Ram 1500 Tungsten, and I just crossed 3,000 miles. I got the truck with 30 miles on it and changed the oil at 500, 1,500, and 3,000 miles. The dealer insisted this wasn't necessary, so I did it myself. After all those years of listening to my grandfather insist that engines should be broken in properly... why not? It's cheap insurance, and it definitely won't hurt anything. This truck is extremely easy to change the oil on, I've always done my own changes on many cars and this reminds me of the old days! The first oil change had a lot of sparkles in it, the second had some, and the most recent had none that I noticed.
I've learned some things after doing this a few times that I thought I'd share...
Let the old oil drain out, put drain bolt back and torque, take the filter off, and new one hand tight only (duh)
Start by adding 7 quarts of 0W-40 (do not put 0W-20 in the HO engine!). Start the engine, let it come up to temperature on a flat, level surface, then turn the engine off and turn the ignition on only. Let it sit for 5 full minutes—this resets the oil level gauge. Then, top off to the level in the attached picture by adding another 1/2 quart.
I'll say that all three times, I just dumped in 7.5 quarts, and the first two times it showed this level. But earlier today, when I changed it again, it was showing closer to max. I was like, WTF, no way—then I learned about resetting the gauge, and now it's sitting right where it is in the picture. The picture is from a YouTube video, not my actual truck, but it's what it should look like.
Once you've done all of that, reset the oil life indicator in the gauge cluster, which is self-explanatory.
*If you have the standard output engine, you do all of this but use 0W-20.
I think using two different weights of oil between two nearly identical motors is going to cause Ram some big headaches soon, a lazy tech or an honest mistake could do serious damage to your engine. There's nothing but a cap on top of the engine to tell you any different. So, while it's new, I'm going to just do it myself.
I got the oil and filter from Amsoil.
