Where did you get the 50hr/4 month figure?

I got the 50hr or 4 month recommendation from Exxon for oil change and
the stated reason was that oil has the capibility of suspending some
water and after 4 months it would become saturated and corrosion could
then begin.

Many people recommend 25 hours if you have no filter.
It's what the service information on my plane says.


That make perfect sense but what Exxon is recommending is 4 months maximium
regardless of hours.
