Winterizing - changing the oil and lubricants

Posted on 07 October 2009

Regularly changing oils and lubricants in engines, transmissions and drive units is a necessary part of normal maintenance, but it is especially important in preparation for winter storage. Once used for even a short time, engine oil becomes contaminated with microscopic bits of metal produced by normal wear and by the corrosive byproducts of combustion. Leaving used oil in an engine for an extended storage period can allow the pollutants to settle into a hard-to-remove sludge and let the acids damage sensitive surfaces within the power plant

The gear lubricant in outboard and sterndrive lower units not only collects abrasive metal bits but is susceptible to contamination by water, as well. Changing it is a must.

There are several things you can do to make oil and filter changes easier and more effective.
