    Oil Filters-gctid812519

    I see marine oil filters, and regular oil filters. Is there any difference? Is one less corrosive? Or there are some internal differences? I used a regular Fram filter last oil change, but heard some talk on the dock that I should be using one of these Mercury Marine filters.

    I also use Mobil1 10-40 Full Synthetic, ....if that's even relevant.

    There's no difference. Just use a high quality filter and it will be OK.

      There have been numerous technical analyses of oil filters....in a recent one I recall reading that the standard fram filters have cardboard filtering elements and was rated as one of the crappiest filters you can buy (I can't recall the source). K&N was also poorly rated...I think that Purolator and AC delco were highly rated. At the end of the day, does it matter? I used to use Fram filters regularly, and never had an oil or filter related issue.

      As for oil, as long as you use an oil that meets the mfr. specs, you will be fine. Change your oil and filters regularly. I always use synthetics in my cars....I try to use them in the boat but I am not as diligent about it since the boats usually get used only in warmer weather. Like filters, oil brands are a religion and people will swear by their favorites.......

        With any OEM oil filtration system, once the cartridge media becomes saturated, the by-pass valve opens up accordingly.

        This means that any oil that the filter cannot handle, goes right on into the engine without having been filtered!

        Change your oil and filter routinely!

          What he said

          I buy my filters at Napa, and get their gold grade. Change oil every year or 100 hours, whatever comes first.

            I do, faithfully. I've just always used Fram, but was just told they fall apart internally and externally in a saltwater environment.

            I used to use Purolator in my vehicles. It sounds like I should return to them, for the boat too.

            Know little about the Napa ones, but the Purolator have a warrantee ....whatever that is worth. B)

            Thanks, Guys.

              A good filter warranty is good to have. Some years ago a customer using AC Delco filters had a lubrication failure that was determined to be the fault of the filter. I don't remember all the failure details, but I do remember that AC Delco paid for the engine (D6 Caterpillar) to be rebuilt. They took care of the customer when their product failed.

                Most filters are just branded........

                Since you spend the money on syn oil.. Don't get frugal on the filter. Not saying that you would .

                Balderson / Cat filters .... You should be able to find a match.. No auto parts stores make filters. They do put their name on them.

                Like oil.... Only a few refineries... Lots of labels
