oil change intervals - usage or time
oil change intervals - usage or time
(OP)
Oil change for engines is recommended both in terms
of running hours or an expiration date so to speak.
As in 2000 hrs or 6 months whichever is first.
Does sythetic oil have any value extending the expiration
time of an oil change. Say in a standby generator that
us run for 1hr/month on average.
Is it a chemical problem that demands a change regardless
of running hours or a profit problem for oil companies?
thanks

Alternatively there may be an additive for oil that would help. I know nothing about that.

RE: oil change intervals - usage or time
I am not a big believer in oil analysis, but if you want to use it make sure you get a baseline sample of oil from the original container and plot the results with the used sample. Make sure you account for the oil added. Oil, like other items has a "shelf life" and a "seervice life". The shelf life of oil in a sealed can may be on the order of 2-3 years. Once opened and installed in equipment it diminishes to 6-12 months.

RE: oil change intervals - usage or time
I am actually working on an oil change policy
for small equipment that will not warrent an oil
analysis.
If operated for an hour per month thereby bringing up
to temp I would hope to boil off condensation and
fuel by products.
So I wonder if on this schedual with syn oil could I
go 3 years without a change 36hr of runtime??
