Gas, yes
Oil, no. Is there an expiration date on that container of new oil? No. Oil is
shelf stable over many, many years.
Manufacturer say you’re no longer covered after, usually, 5 years.
Which manufacturer, vehicle? Oil?
There must be another reason than just trying to sell you their stuff.
"Must be"? Are they not in business to sell you stuff? For what other reason?
There is, in fact, another reason,as well. They must retain reserves to cover anticipated costs of warranty claims, or
show them as contingent liability. In any case, there is a balance sheet reason.
Then I put it in an engine that isn't used for years. What has changed that
would cause it to deteriorate?
I did some web research on this. Our Mercedes Sprinter has this smart oil life
calculator. One day, based on time, mileage, temps, etc., it says the oil is
good for, say, another 7,000 miles. The next day, is says it needs to be
changed right away, because it's been in there a year.
Mileage OR time - the first one of either, else you lose the guarantee and have to pay any
damage from your own pocket … In truth I don’t care, servicing is included in
the extensions we buy for our cars ;-)
Our vehicles are long out of warranty/extended warranty.
Diesel and/or turbo charged engines require careful attention - electric cars
less ;-)
The old x,000 miles or one year rule is based on an unstated assumption, that
the car has been used regularly, but for only very short trips, the kind that
are hardest on engine and oil.
In the case of an RV, which sits idle most of the time, then runs up most of
its miles on hours long trips, that assumption is invalid. Also invalid for a
car that has been in storage.
Ask anyone with a chainsaw or a lawn-mower that only occasionally runs why they
nevertheless service them regularly, and empty the tank before storage.
That's easy, because they have been taught to do so.
Or learned from facts and experience in my case.
Trouble you can accurately trace to engine oil alone? Gas mixed with oil will
deteriorate, indeed.
My chain saws, hedge trimmers, etc. are electric. Far less fuss and bother. The guy who does our heavy duty, once a
year, trim is now using a cordless electric chainsaw. Loves it.
