Re: 2005 Monticello

Have put only five (5) hours on engine this season. Oil was changed last fall upon de-comissioning. With so few hours, is it necessary to change again when winterizing? Usually run 30 - 40 hours/season and have always changed oil when  winterizing.

I would take a thorough look at the oil on the dipstick, and if it looks good, save your money and skip a year.  The reason to change oil before winter storage is to prevent  the corrosive agents created by engine use from sitting stagnant over the winter months, and causing damage over time.  With only 5 hours, I doubt your engine oil has gathered many of these corrosive properties.
