Re: Frequency of Changing Oil & Fuel Filters
Westerbeke has nothing to gain by promoting the use of synthetic oils and therefore it becomes a liability to invest in the research to confidently advise that oil changes can be extended to certain intervals. I wouldn't expect a company like Westerbeke to give two shits about people wanting to extend the life of their engines if it meant they had to spend money to do the research. There has been enough research done by innovative engine manufactures like Volkswagen, Mercury, Cummins, BMW, Yanmar, Volvo and the like, that it is not even an option to use mineral oils in many of them. Synthetic oil manufacturers have published the results of all their tests which show that the use of synthetic oil has only positive effects in engine longevity, oil longevity, filter longevity and the overall efficiency of the engine. I know change is scary, but so is living in the past.
