Highway 4x4 At 6K miles a year I do it every year before my summer trip. I do it myself, fuel and all. If it gets screwed up, I did it. But it doesn't and I keep it clean. I let the oil drain overnight. The oil change is a good time to inspect everything.

Tractor: Every 300 hours.

Very unlike the Ram, the tractor should have its first change at 50 hours. Makes perfect sense to me, getting the break-in crap out of there early, and why I do the same with Rams instead of letting 15,000 miles pass.

Also interesting is that after that initial oil change on the tractor, with a 300 hr interval, the filter is only supposed to be changed every 600 hours.
Naturally I change the filter, too, while I'm at it.

So here we have two turbo charged diesel vehicles that cost about the same. Why are the oil change requirements that different?
My guess is that while a tractor may sit for months, when it gets fired up it's not to go to the corner store two blocks away. Instead it gets used and properly warmed up.

The bottom line is that effectively I'm forced to change my oil every six months on the Ram because so many use theirs as a car, and Ram knows it.
Okay, that's not the whole story. As mentioned, most other vehicles don't have this dumb time based interval, but FCA has seen the opportunity to profit from improperly driven vehicles.
On my new work truck, Cummins, I mean Paccar, basically says no matter how you look at it, 500 hours. I'm OK with that.

BrianF Some good insight on here. I go by mileage, not time. Cummins provides oil condemnation limits for the ISB6.7. Time was not one of them.

Using used oil analysis, I plan on extending mine out. Planning to run this current fill to 30,000km or 18k miles and see where it sits. So far from what I have found, 24,000km barely adds any fuel, soot or depletes the additives or shear the oil past its limit. That's with all that garbage emissions intact.

Rest easy knowing this engine does not really care what sort of oil it has in it. Run CES20081/86 and grade for your climate and be done with it.

Well, fortunately for me, that has never happened. Happened to my dad's psd while getting a change out on the road, but of course, he didn't find out about it until the next oil change, and not like he could take it 1200 miles back to the offending shop.

That pretty well makes my case for doing my own oil changes. My sold 2006 6.0 F-350 had a rounded drain plug thanks to Walmart oil change while on a out of state RVing trip. I made a set of home made ramps. When on a longer trips, I have oil & filter on hand and I'm not at the mercy of idiots who have the mind set, "I'll not see that truck again." Not a fan of Wally world. Walmart can pound sand!!!

camperman @Jimmy N. I've got a Fumoto oil valve on my truck. Its kinda like the Karate Kid when Mr. Miyagi said "Danielson, wax on, wax off". I sure likes that fumoto thingee.

Ltngdrvr Haven't had a dealer oil change that they didn't make a mess all over the frame and tie rod, that I would have to pitch a fit over and have them take it back and clean it off.

So much for the "Free" oil changes included with my truck purchase. I think I still have one oil change left that I didn't use.

Dogpatch I get them to do the oil change on my truck. They supply.
I also get them to do my fuel filters, however, I supply the filters via Amazon.

camperman While there is nothing wrong with the dealer changing the oil, I like doing it myself. I let it drain for 45 minutes or longer. Doubt the dealer will do that, maybe, but probably not. I know it was done right the first time. Most of the oil change techs are just that, they know how to change oil and not much more. The more knowledgeable mechanics are doing actual repairs that are above the skill set of changing oil.

I do understand that some don't want to change oil. Some due to age, or schedules or work, or physical limitation that may prevent them from doing it, and that is fine also. When I first took ownership of my '12, I asked the dealer for oil changing pricing. Was quoted approx. $120 or so. I can change my oil for $55.00 give or take. The extra that I save I can spend at Geno's Garage for filters and the such. However, may way ain't right and the other fellas way is not wrong either.

You supplying the oil and filter takes part of the potential for things going wrong away, but they are still doing the job. Are they doing it right?
Just gotta trust them, and the blackstone results. Not gonna drive myself too crazy over it.
