Oil change prior to winter storage

[KHE]

I normally change the engine oil on my 350 5.7 EFI engine as part of the winter storage prep. This year, the weather and lake conditions have been bad - especially the spring - April snow showers, then April rain showers, May and June showers...

I normally change the engine oil every 75 hours which works out to about mid-season and then as part of the winter lay-up routine.

Currently, I have only 25 hours on the oil as my mid season, 75 hour oil change didn't happen until August 11th. I'm thinking about forgetting the oil change this fall but am not sure if that is a good idea. Thoughts?

Sounds like a good plan to me.

I just asked this the other day on another site. Put 10 hours on it this year and about 5 of that was sitting in the dock idling when it wasn't running right. I was persuaded to change it anyway. It's Shell Rotella 15W-40

Take a look at the oil. If it's still "clean" you'll be fine. It really will only mater what makes you most comfortable.

You should be fine but comes the spring i would change it after you splash it. I'm a firm believer in keeping the oil clean and sticking with the same brand. that oil has already started to break down with impurity's in it. Another job of the oil is absorbing the heat from the engine. Just my opinion treat it right it will treat you right

Shoot, a typical year for most of us Michigan boaters is 40-50 hours of runtime. You're over half way there!

If I were in your shoes I'd change it. Sub $100 invested and you'll have a more enjoyable off-season knowing you did the right thing

I typically put 150 hours on in a season but the weather has been so lousy this season, it is going to be just over 100 hours.

I will change the oil - just to be on the safe side.

I see the Grand Haven South pier lighthouse in your avatar - that is my home port.

Wow, that's a lotta hours for a notherner! Nicely done. I haven't checked mine yet for the year but with a trip to Chicago and Leland (from Grand Haven) this year I may be a bit above my typical average.

My home port is also Grand Haven. Sad to have missed the re-lighting of the pier last night!
