Changing Oil

Opinions will vary, as with any discussion, but there's one thing, I'm absolutely and positively convinced of and that is that we're wasting far too much oil in this country with unnecessary changes and all this while we're running threads on the price and MPG of fuel.
Now seriously, when was there ever a documented failure of an engine, because the oil hadn't been changed frequently enough and most likely the causes were because it was without oil?

I fall into the camp that stretches the interval between longer when I don't put many miles on. Over the years we have averaged 10k per year and changed at least annually. Now we sit more than we travel, by choice, but travel longer distances per day yet so I will go out to two years between, but not longer. I've supported my thinking with oil analysis and am comfortable doing this.

I'm currently at 99k on this coach and have never had an engine issue related to oil on any of the three we have owned.

As to what the OP should do, I would simply say weigh all the advice with your own logic and decide what you are comfortable with.

This is the correct answer.
$28.00 due when you send back sample in container they provide you.

Very comprehensive report including per cent of life left in the oil.

THEN YOU KNOW and are not guessing

Call a local RV Mobile Repair in your area.

Call the closest CG to where you live and ask the CG owner who they use for RV Mobile Repair.

They come to where your MH is and within an hour or so it will be done. So you do NOT have to take it and leave it anywhere! Convenient, less expensive, AND IMHO better qualified mechanics.

Its been 1 year since our last oil change but we have only put on 2000 miles. This is on a cummins engine. It's not about the cost it's about taking it and leaving it for a couple of days. Would you go ahead and have it changed? Only plan on putting another 3 or 4000 miles on till this time next year and then having it changed.

Thanks for all comments

I forgot to mention this is a RV

I think it would be a total waste of money at this point. There's nothing wrong with the oil that's in it. It doesn't expire or go bad (at least not that quick).
It takes me around 16~18 months to put on enough miles between oil changes. The truck doesn't watch the calendar and it's fine with that routine.

Oil and filter changes are cheap insurance. My truck does
Not get driven a lot either, 38K miles in 10 years, but I still change it yearly.

NO, I change mine every 10-15,000 miles which can be 2-3 years. There is not any moisture in the oil of a engine that works hard when used... not driven to church only on Sunday. Your engine gets hot enough to boil any moisture out and oil does not go bad even in five years.
