What is your frequency in changing Oil in D/P and the Generator

[Kro1957]

Curious what your frequency is in changing the engine oil/filters along with the oil/filter in the Generator.

I have been doing 2500 or 1 year which ever comes first. The 1 year mark always hits first.

[Mr_D]

I'm one two years with mine, BUT, due to the late DW's health and death I've only driven it 2000 miles or less since the engine was rebuilt. I did an oil analysis and they say to resample in 500 miles as silica is high.
My engine takes 14 gallons of oil so it's not a simple change in the driveway anymore.
Spcs call for 15,000 miles or once a year.

Since my Cummings burns no oil, I replace it every other year. Generator gets more hours, so at least twice a year.

Mr D,
1st , it always makes my heart sink to hear someone mention their spouse has passed and my thought and prayers are with you.

2nd. You mentioned the quantity of your oil, several gallons, mine is the same. I did have a special plug on the drain that has another piece that screws on and it has a valve. I just keep a set of empty gallon Rotella jugs and put one at a time under the drain valve, give a 1/4 turn on the petcock valve, fill that jug, turn off and rotate in another one.

I might add, that I have wooden blocks that are about 9" high with a large footprint. I put them under my stabs, run the stabs down and it raises the coach up really high. So high I could put a 5 gallon pail under there if I wanted to. (an older, or I should say experienced motherhome guy showed me that trick). I do this in my storage unit and I have never spilled a drop.

Really, I am amazed how easy everything is to service this way. From filters to grease zerks all much much easier than it was for me to service my F350 7.3L Diesel. I do also use a large shallow drain pan just in case I do something stupid or drip but that is just in case.

Note, Uncle Bill, My Cummins does not use a drop of oil either and we have not been on the road that much to rack on the miles, but someone or somewhere I read or was told a person should not go beyond 12 months on oil changes. At least I thought that was the case, perhaps I got my time interval wrong. Would 18-24 months be reasonable under 2500 miles?

I know this information is in my coach and my maintenance records, curious what you all do for good measures.

Cumming 1100 0 (rough) , 1 year max.
CAT has the added comment, 1000 gallons of fuel burn, 1 year or 11,000 mile

Either engine EVERY year, so don't take a chance.

Generator, I do at the same time, every year. Small cost to pay, to keep things running.

[DENSHER]

My manual for the Cummins 5.9 list engine oil & filter @ 5000 miles or annually. 5 - 6000 miles is our average use so I do it annually and genny at same time.

[Playtime III]

After market, extended service plans are usually very explicit about this. If you don't follow MFG maintenance guidance, they will deny any claim associated with that item. My GS ESP mentioned this in several places and in ALL CAP/BOLD.

[Crasher]

My Cummins manual says 15,000 miles. We put on about 10,000 miles per year and change oil, oil filters, fuel filters, generator oil and filter once a year. Never add oil to either one. Some years the generator will get 75-80 hours.

[Kro1957]

Well, it sounds like I am doing it right by the 12 month intervals. I never have come close yet to the mileage. This next year I might though.
And yes, I do the generator on the same interval time. Fuel filter also. Same time.

[MSHappyCampers]

Once a year!

[JMonroe]

Cummins says 6 month change intervals for oil changes, regardless of miles. (ISX 15) This is totally insane! Dump 14 gallons of oil with only 500 miles since the last change!? October through April we might put 500 miles on the coach.

I'm sticking to my once per year service interval, done every October/early November just before we get settled on our Florida site for the winter.

For what it's worth, I've tried multiple channels through Spartan and Cummins to get their reasoning behind the 6 mo interval, they've all failed or refused to directly respond to that core question.

Lastly, they can't refuse warranty for failure to comply without showing a direct correlation. State and federal warranty laws will forbid it.

You're referring to the Gederal Moss-Magnusson Act.

Actually they do refuse and your recourse is to sue them. Dodge did that to many owners. Usually the cost of suing them is more than the repair, plus your vehicle sits for a couple years waiting for the case to be settled.

Cummins (Not Cummings) says 15,000 miles or 1 year, whichever comes first. We do the generator at the same time. Cheap maintenance.

[asuperheat]

Like most I change it once a year in both. Every January for me. Use it year round here so no real storage time.
