One oil change in 11000 miles?

"JMO but some folks waste good engine oil."

Amen, a 2,000 mile oil change interval is simply pouring oil, and money, down the drain. A complete waste of resources.

The Cummins '03 to '07 5.9 HO gives us a 7500/15000 miles oil change service schedule.
My '03 5.9 HO Cummins is at 320k + miles with mostly a 10k average between the two schedules. No issues with 50k oil analysis checks.

I see many LDT diesel commercial haulers are using extended oil changes. Example... using a good synthetic oil for 15-18k miles and a filter change in between.

JMO but some folks waste good engine oil. Engine oils today aren't from the '70 era thankfully.

It did not go 11,000 miles
It went 6000 and was changed
And is now at 5000 more, and ready for another oil change

According to the first post

I live out in the country. Commuting puts a lot of miles on the vehicles. My daily is at 305k miles, and my wife's daily is a 296k miles. Original motors, untouched. I have been religious about changing oil at every 2k miles. I believe it is the cheapest maintenance I can put in to a motor (around a penny per mile). About $20 and about 15 minutes of my time.

That's my experience and I am standing by it. Your experience may be different.

The other benefit is I am under the hood of the vehicles fairly often. A small leak or other odd problem is occasionally spotted indicating some sort of wear item (ie: water pump) is having an issue. Because I am doing regular maintenance, I see the issue before it becomes a problem that leaves me stranded on the side of the road. Going 11k miles on an oil change tells me that hood hasn't been opened in a long time - and who knows what other maintenance issues were left to deteriorate.

Change the wording all you want but one oil change at 11,000 miles with that oil change occurring at 6K is not a problem. And if it was synthetics, you can go quite a bit longer.

Changing wording does nothing to correct a lack of comprehension. The OP stated that the oil had been changed once in the lifetime of the rig. Manufacturers recommend frequent, often annual, changes to remove condensation and degraded oil from the crankcase based on both mileage and TIME metrics. As for buying into the extended interval BS, by all means, go 20- or 30K. I listen to pros. that make a living replacing engines and repairing damage caused by those that believe that oil will last a very long time, doesn't get dirty, doesn't suffer a degrading of the additive package, and doesn't get consumed at a much faster rate as it degrades. They do all of this since they listen to two stakeholders that benefit greatly by encouraging you to believe in extended intervals, that being the OEM and the oil marketing folks. The fact that it doesn't actually work in the real world is of no concern to, and considerable benefit to both. My Ford V-10 cost me about $25 to do an oil change on. It's a quick, easy DIY task. A replacement engine runs well over $10K, installed. Even IF there wasn't a huge body of evidence that extended changes are BS, the amount of time and money spent to do 5K intervals is trivial, compared to the risk of a short lived engine.

Change the wording all you want but one oil change at 11,000 miles with that oil change occurring at 6K is not a problem. And if it was synthetics, you can go quite a bit longer.

Every 5k miles and I use the cheap stuff at O'Rileys. 280K on the Excursion and 230K on the F150. Go ahead and change oil every 10-15K, your engine might only last till it's out of warranty. $$$$$$$$$$$$$$

O.P. run, run, run from that MH

If they didn't bother to change the oil only once in 10 years, what else didn't they bother with? Skip it.

Some of the posters here need to re read the oil service info in their owners manual.

6000 miles is not that bad , your heading says 11000, that is 2 many

For a motorhome, probably, but the wife's Grand caravan has gone 11-12k miles between oil changes. It has an oil quality sensor and we change it when indicated. The first time I was a bit sceptical but we sent a retain sample out for analysis and the oil at ~11,400 miles had 20-30% additives left and a fairly low breakdown percentage (was still redish when you looked through it, not blackened)

It's your money, but you might want to give this a bit more research. I've got a good friend who is a top notch independent mechanic. His shop gets at least one engine replacement job, and/or a $3-5K repair job to valve gear, timing chains, heads etc.... that they can directly attribute to changing oil at 10-15K intervals, at least once a week. Manufacturers, including GM and BMW and others, are quietly backing off the 10-15K intervals, by reprogramming software, and issuing TSBs. BMW made a very big deal of extended intervals, then discovered that it made for engines that self-destructing at the 100-125K mile range. I do DIY changes with Mobil 1 Synthetic and an OEM filter, every 5K on my vehicles. When looking for any used vehicles, I will not touch anything without documented changes at the 7K mark, or less. Subaru, GM and many euro luxury brands have all found that extended changes are less than optimal.

Yep, the Oil Life Monitor was designed to make it seem like the vehicle you bought requires very little maintenance. I too have seen the effects of following the oil life monitor. I wouldn't go beyond 6k miles. and that is pushing it. As a technician myself I don`t go over 5k miles on a vehicle with synthetic oil. and 4k max on traditional oil. $40 for a regular oil change is cheaper than any engine repair related to poor oil change schedule.

Yeas indeed, the whole, "maintenance free" scam is making for an entire generation of vehicles that either die an early death, or end up needing thousands in repairs that could of been avoided. My mechanic buddy is of the opinion that (based on constant communication with his customers) many owners are equating the claims of nearly maintenance free vehicles, and a dashboard that tells you when to actually have work preformed, to the delusional belief that they only need to put gas in the thing, and drive it to the quick lube when the service light comes on. In their minds, there is no need to lift the hood to check anything. As a result, they didn't know that the engine, built to extremely tight clearances, and full of dirty oil, is consuming a quart every thousand miles, once the oil has been in the crankcase for 7-8K miles, or that some cars will start ravenously sucking oil way before that, particularly some Subarus. Several times a week they get cars in his shop with a bone dry dipstick. He claims that, a decade ago, this happened very, very rarely, and now it's an epidemic, along with totally shot engines in 5-6 year old cars with 80-120k miles on them.

I could see success in 10,000 mile intervals running a quality oil but only under perfectly ideal operating conditions. By that I mean start the car and take a long drive at reasonable highway speed’s without temperature extremes or stop and go traffic. My daily commute is far from ideal. I do a coldstart 2 mile loop to drop my son off at school. Then about an hour later I drive 2.5 miles to work. The car then sits for 10 Hours, followed by a 2.5 mile ride home.

My oil rarely reaches full operating temperature and has no chance of burning off any impurities. I change my oil rather frequently, but it takes me 15 minutes and cost me about $20 in materials
