With Decent annual service, running this engine in your RV, you will No longer be eligible for a Driver Licence before this engine wears out.

I work on it more than I drive it. Always servicing it. Wearing out is the least of my worries. My lift pump is getting weak so I guess I will change it next.

I don't think I'd ever be able to afford enough fuel to wear my Cumming ISL out...

The engine itself being properly maintained will last an easy 500,000 miles,,, usually a lot more. I drive a truck, and from what I've seen (in big truck engines, mostly Cummins that are worked a lot harder than rvs) the turbo will blow around 500K miles. You might lose an injector before then, but as most rv's, time will take it's toll more than miles... My company has stuck with Cummins for the most part, but have tried most all engines over time. I drive one of 27 in our fleet (over 10,000 power units) that has a Cat motor. It's a C15 466 but the ISX 400 Cummins will run circles around me. I know it's a lot how they have the computer set, but also I see fuel mileage, the Cummins get at least 1 mpg better... Sometimes more.. If I can ever afford a DP,,, or a pickup and fifth wheel, it will have a Cummins... You should see the mechanics in any of our shops cringe when you go in with a problem, and tell them it's a Cat..

My ISB has 183,000 miles. Runs as good as new.

No we are not the original owners. Actually we just bought it. The original owners are 80 years old. And traveled all over the US with it. But took VERY good care of it.

1992 American Eagle 8.3C - 1st Owner= 52,000 mile.
Bought it in 2000 now has 185,000- Oil Analysis last May was near perfect.
I change Oil and All Filters @ 10,000 miles. Other PM is on Cummins and Spartan recommended schedule.

I should reach 250,000 miles on my Cummins sometime around my 116th birthday.
And the MH will only be 56 years old.

First DP had at least 250,000 on in. Don't actually know the total, but it was a Euro Premier and the whole rig fell down around our ears over the next three years. The Cummins 8.3 300hp still ran like a top, as did the 5sp Allison trans. The rear cap literally began falling off the day we traded it in.
Current rig, '96 HR Navigator 400hp Cummins, we bought with 57,000 miles 7 years ago, now has 142,000 and runs like a clock. We usually cover much of the country each year either with the RV or toad. We have come to the decision that either a Cat or Cummins will be running long after your RV has disintegrated! When we started, my trucker buddies told me an 8.3L is about a 500,000 mile engine when if cared for well, and an 11L is about a 1,000,000 mile unit. The only RVs for which those miles even mean anything are bus conversions, the chassis' and bodies of which are designed for multiple millions of miles if needed. If you want, you can start over from scratch with a bus conversion and simply rebuild it into a fresh new rig. We'd be hard-pressed to have any fiberglass unit on the road today be enjoyably used beyond 300,000 without serious attention, both in and out.

131k on a 1992 American Eagle, I put 6k on so far.

It had multiple owners, at least 3 that I can tell for sure. We change oil as per the manual every 6000 miles. I noticed someone above with the same year does 10k. Interesting, not what our manual says, but maybe he does oil analysis.

My 2007 ISL has 97k, will have 105k by the end of the year. Zero problems except for a thermostat at 82k.

I do Change the Oil and all of the filters every 10,000 miles and that would be 2 to 3 time a year, The genny gets serviced every 150 hours about 10 times a year as I run it often !

'04, 3rd owner, 20535mi. Trying to put more on, Really!!!

Second owner 74,000 mi. Don't mean to hijack the post, but does anyone use the Lucas Oil Additive when changing oil? My unit is a 2002 Cummins 8.3L and is one of the models where Cummins placed the CrankCase Vent outlet just below the exhaust manifold. When the PAC Brake is used very much the drip pipe lets the heavy oil vapor drip out and can use as much as 3-4 qts in a very short time. Of course Cummins had a so called "Campaign" where they came up with a fix if you happened to find out about it. Since I bought used, the "Campaign" had expired. So, I have been adding 2 to 4 qts of the Lucas at oil change intervals, that seems to help with the oil loss, expecially when the PAC Brake is used. Any one know if these thick additives hurts the engine?
