I know most vehicles (RV included) require oil changes every 4000-6000 miles. How long do you let the RV sit in storage before changing the oil (assuming you are short on the mileage)?I plan on using the RV at least once a month during spring and fall and twice a month during the summer. It will probably sit in storage all winter (2-3 months).

I use synthetic oil, and do not worry about how long it sits. I do think that it needs to be started, and let run until it warms up well, to keep fresh oil recirculated from the drain back up into all the engine parts. Without mileage, the age of the oil makes no difference. With synthetic, I plan oil changes closer to 10,000 miles, whenever it is convenient.

Conventional dino oil breaks down over time. That means if you only use your RV a few times some years you still need to change oil about once a year at least. With synthetic oil it is possible to go much longer.

Don't know about your 2007, but for our 2003 E450 Ford recommends their Motorcraft 5W-20 semi synthetic oil. The filter is the Motorcraft 820S. Both available at Walmart.I change the oil and filter every 5,000 miles, although I have gone over that number somewhat a few times on long trips.During long periods between trips (mainly Winter) we take a drive to a mall about 20 miles away to give the engine, drive train, brakes and other moving parts some "exercise". IMO regular exercise is good preventive maintenance.

Sealed up inside the motor. not dirty unless it is ran. should last as long as it would in a can on the shelf.

I change mine at 10,000 miles regardless of time. Ford calls for 5,000 and some time interval... so what.I do not make short trips. Always put away hot. 190k and doing just fine.

Once a year is enough, and 10,000+ miles on full synthetic is no problem for the V10. I've gone as far as 15,000.

But if I had to run a lower grade oil, or doing lots of in-town driving, then I did it at 5,000 miles.

I generally use the Napa Gold filter. It's good and cheap. Usually on sale for ~$7.

Minimum every spring and every 5,000 miles during the season with semi synthetic. Oil is cheap. Engines are not.

Send a sample to blackstone labs at 5 k and then you will know what your engine is doing based on your use.

Motor oil does not break down sitting in storage.

Oil change recommendations based on time assume that the vehicle is being used regularly (almost daily) but only for short trips. This type of service is harder on lubricants than continuous non-stop use, which drives the mileage recommendations.

The. way you are using yours, I would do an oil change before putting it into storage for the winter.
