This truck is going to take some getting used to, that's for sure. Back when I was running a Wix spin-on filter on my FASS pump on the Dmax truck, I changed it more often than necessary because it was $18 and literally took 1-2 minutes to change.
Now with $120 in fuel filters (online) I guess I will get more of the goody out of them. I'll carry a new chassis filter with me and hope I never have to lay under the truck and change it like I've done in the past on my FASS.
I used to literally change the oil in my Dmax for less than $35 using T4 from the drum and a Wix or ACD filter. Just did my first change Sunday and it was $75 for just oil and filters. In all fairness, some of that is Covid tax.
Used to plan 10k OCI on the Dmax, sometimes running to 12-13k when I got back home again. Haven't decided on my Cummins OCI yet. I'll probably pull an oil sample to have tested this go round.
