Yeah now that I have a “15,000mile” interval Ram and stepped up from Dino juice to syn on the new truck, I will be doing roughly only 40% of the number of oil changes that I do on all the gassers.
Will see if I can let myself go 15k though, lol. I just changed at 10k last weekend, but idk what was in it or oil from the previous owner. It had fresh oil change and fuel filters when I bought it.
One observation, front filter at 10k miles was cleaner than expected. I wouldn’t hesitate to go 15k on fuel filter. Front one at least. Didn’t cut open the back one.
