I run liqui moly 4100. I run 5w40 because I want something a bit thicker than what the manual calls for.
Liqui Moly Toptec 4100 5W-40 works if you feel like you need something thicker, but these diesels don't run crazy hot like gas + turbo engines.

Generally agree with everyone here that it doesn't matter that much.. except for the relatively new Valvoline restore and protect. Seems like it actually does gradually clean out your engine and it's not just marketing bs
I’ve been running it in my 1992 Nissan D21 truck with over 200k for the past two oil changes and it’s gotten rid of a lifter tick it had for the past 20k miles. Runs a bit quieter too. Pretty good oil.
I've been using it for the past 3 oil intervals. I've seen a few oil analysis on the stuff with a few that came from FA24 engines and its wear protection is just as good or better than any GF6 oil out there. Its supposed to also meet the New GF7 oil specification as well that just came out in March.
I’ve had great luck with “Valvoline Restore and Protect” I have a Sportage with the same 2.4L, it burns 4-6 oz. every 3,000 miles. Used to burn 1 qt every 500 miles.
So I went from valvoline max life full synthetic 10w-30 in my k1500 92 gmc sierra sle with the 350 and tow package, flat tapped cam truck, to valvoline restore and protect 5w-30. I was having oil pressure issues, only 188,xxx miles. After switching to R&P, 1500 miles into the oil change, I consistently have above 30psi oil pressure.
I use top tec 4200 5w30 but I change it every years and I’m not driving much.
Yamalube is a good oil, nothing special. Get a more premium oil if you care about smoother, stronger performance.
