Oil Type & Hour Meter

Howdy, I have a 2020 Dutch Star 4081 on a Spartan K2 Frame. The motor is the Cummins L9, 450hp. The owner’s manual gives me the oil capacity and intervals. However it does not give me any information that I can find on the recommend type of oil. Coming from gas powered engines there is always opinions on what is the best type, but I don't seem to be able to find any such information for diesel. The other mystery I have is the manual talks about hours on the motor and refers to the hour meter, but I'll be darn if I can find anything that looks like an hour meter. Does our coach engines have such a meter? Any thoughts or input on oil or meters would be apprecheated.

Several long-time favorites (do a good job AND are available everywhere including Walmart):


Shell Rotella T 15-40


Delo 400 15-40.


Certainly, there are other quality oils, but finding it everywhere is one of my criteria.


Some use synthetics, but I have yet to hear of an oil-related engine failure on any diesel using "regular" oil. Sure, if you want to extend your annual oil change to 20,000 miles, perhaps a synthetic or synthetic blend would be worthwhile. Under 10,000 miles in a year-- pretty much a waste of $$.

I run the Rotella T mentioned above. I buy it at Walmart in 2.5 gallon jugs. You need two of the 2.5 gallon jugs, one 1 gallon jug and two quarts (26 quarts) for an oil change.

Install a Fumoto valve in place of your drain plug and oil changes become pretty simple. The first time you can't do it, but I save the 2.5 gallon jugs and on the next oil change, you can slide them right under the coach, open the Fumoto valve and fill the jugs. For the first change, just use some old DEF containers.

You can install a Fumoto valve two ways before the first oil change. First way, people hook a ShopVac up to the oil dipstick tube, remove the drain plug and install the Fumoto valve. They say no oil drips out. I just put a drain pan under the coach, have the Fumoto valve ready, remove the drain plug and quickly install the Fumoto valve. I lose a couple of ounces. Once drained, I remove the Fumoto valve, clean everything up, reinstall and tighten.

I've never looked, but you might find an hour meter if you scroll through the dash display. Often, something like that is an option that most manufacturers don't use/install.
