When I first got this rig, I tried the recced PYB 5w30 and found it sherred down and caused engine noise at less than 3k miles. 10W40 lasted a little longer and no noticeable engine tick at startup until 4k. Delo 15w40 lasted almost 4.5k miles.
These motors are very hard on oil. A sub 3.5 qt sump and a tiny filter. There are a few Mobil1 analyses on here showing completely worn out oil at less than 5500 miles.
We recently took a cross country road trip. Before the trip I filled up with delo synthetic 5w40 and a fram ultra filter. We did a lot of hwy, a lot of offroading, and climbed to over 13k feet.
At the 4k mile mark, the engine noise started. Just an ever so slight rattle noise that signals the oil taking a beating. Unfortunately, I wasn't in an area to change for another 500 miles.
Tried to pay for a simple drain and fill as I didn't wanna remove the skid plates or ditch the fram ultra after only 4k miles. I also couldnt get delo 5w40 and instead could only find rotella 15w40 synthetic.
Drain, filled, and drove the 4k miles onward/home.
My question is:
Delo 15w40 is the cheapest oil at about 8.99 a gallon. I like the idea of an expensive filter, but with oil not lasting past 4k, it needs to go to two drain and fills to make sense.
Is there any harm is doing a drain and fill of 15w40 delo every 3300 miles and swapping out the fram ultra every 10k?
The engine is clean as a whistle from doing 5w30 changes every 3k. I'd just like to save a little money if I can... All while getting a cleaner better protected engine.
