Re: 2012 15 hp Mercury Outboard 4-stroke
I always change my underware when taking a shower so everything is good and clean. The same should hold true for all oil changes, as the filter is dirty and they are alot cheaper than a new motor. Most all auto supply dealers should be able to get a oil filter for your motor as most of them have a Serria parts book in store and can get the correct filter for your motor. Only diffrence will be that it will have a diffrent brand name than Mercury on it, and will be alot less in cost. The use of the new synthedic oil might be best , but that is up to your choice as it dose cost more than a good grade standard oil of today. Just remmber that cost of a oil change is alot cheaper than a motor. Good maintance and storage of motors will make them last for a long time. JMO
