Post subject: | Oil Change before winter? |
I live in Canada and my 195 will be stored indoors (not heated), I have to run antifreeze through the motor which is fine but im wondering if its a big deal if I change the engine oil before or after the winter. I know of people who do both but I was looking for a genuine reasons for or against. What do you think? |

I would change before you out it away. Putting fresh oil in removes all of the bad contamanents that are in there. |

Change it after. New oil will break down over the winter and ruin your engine. Nawww, just kidding. There is no RIGHT answer to this question. Its like "which oil/sparkplug/prop/radio is best", there will never be a right answer. You can do it before or after winter. |

My tech always says to change it in the spring because the oil accumulates moisture while sitting during the winter. Sounds plausible but I have changed oil in fall after a busy season to not change it again until summer. Does once a year rule? |

Once a year is fine, I always do it in the fall. I don't think that any contamination that could happen over the winter is significant. Think about it, you buy a new boat, the oil was put in at the factory, they do not change it at the dealer before they sell it to you because the boat sat there for 6 months to a year. And about running AF through it, well, unless you know exactly what you are doing, this could cause a cracked block. Because the 'stat may not open all the way on cool fall day. Some remove the 'stat, some drain the block first. I like to drain everything after changing the oil and fogging it. Then I simply back fill the engine, manifolds and raw water intake hose through the hoses with the best -100 marine AF with corrosion inhibitors. Safe easy and no risk of cracked block. ALWAYS probe all drains to make sure water comes out!!! |

Re: Change oil in fall or spring? change oil/lubricants in the fall/end of season. you want fresh oil in your motor over the winter to stop/slow corrosion of internal parts. dirty motor oil can become acidic and attack engine parts and that's why the oils advertise having corrosion inhibitors in them. also if you drain motor or foot oil and it's contaminated with water or normal wear deposits, then you want to get that oil out of your motor and make any repairs to seals or other mechanicals right away during the off-season. |
