Thanks

After the oil change I top off the fuel tank, put a biocide in it, and park it.

Is biocide something that goes in the fuel to kill bacteria?

YES.

Acid? Moisture? I call FUD. Get it tested.
Although I do understand the warranty thing as long as it is the OEM requirement and not the dealer drumming for business.

Bob I hear you man airplanes are a different animal and your fuel deal is a different ideal than engine oil
I wont argue the airplane angle ever but these are motorhomes and they don't have to fly LOL
everyone has the right to change their oil every 30 days if they so desire or once a year or every 6 months it matters not to me
I opined that mileage is when I change mine.People whom opine that your bearings will etch and fail if you dare go over a year simply have no idea what their talking about at all there is no such thing in the modern world of oils and engine parts

If you live in cold country or the south then in the Fall. Get's all the acid out of the oil and won't run the risk of etching the main rod bearings.

If in the mid section of lots of freeze/thaw then in the spring before startup. Get rid of the moisture that can accumulate over the months that would tear up the main rod bearings.

YMMV

sorry man with todays oils and engine bearings there is no such thing
what moisture? where does it accumulate and how?

Hmmm, back when I was flying we always filled the gas tanks after a flight to keep the air space to a minimum in the fuel tanks. The logic was that air space contained air and air traps moisture (humidity) which with temp changes would condense out into water going into the fuel. (We'd also drain the water out of the bottom of the tanks before a flight as part of the pre-flight inspection.) Unless you have an air-tight crankcase or fill it to the top with oil I can't imagine why the same thing couldn't occur in a crankcase. All of which would tell me to change the oil in the Spring unless the engine was run periodically during the storage months and brought up to temperature so the water vapor could be driven off.

usersmanual you had your say we all know how you feel, you don't need to keep defending your position. I change mine in the fall as there are acids and such that"can" do damage to a motor. I also change the fuel filters once a year in the fall also, may not need to but I never have had a problem. OH do the same on my gasser now.
From the book for RV ISL motors
Routine Maintenance Recommendations
Check oil level daily.
Oil Drain Interval Fleetguard Filter
20,000 miles / 12 months LF 9009 (all ISL models)
Replace oil filter at EVERY oil drain interval.

LOL OK . by the way there are zero

acids and such that"can" do damage to a motor.

just so you know
