I was wondering if it is recommended to use Yanmar brand oil filters for a Yanmar 3GM engine. Are these superior filters to the premium Fram brand or others? Also, the manual recommends oil changes every 100 hrs with oil filter changes every 300 hrs. I am use to changing oil filters in autos every oil change. Should I be changing the filter every oil change instead of every three like the manual recommends?

Yanmar
At a Yanmar engine service class last year, the instructor told us that the Yanmar filter is designed to fit the engine in a way that substitutes are not. That was good enough for me.

What I have heard:
You must use a Yanmar oil filter. No exceptions. Most automobile-type filters are designed to trap particles at the end of the cycle: oil pump, system, filter, pump, system, filter, etc. So the oil pressure the filter is exposed to is much less than the pressure just after the pump: maybe 30 psi. Yanmars place the filter just after a high pressure oil pump, at 80 psi. That pressure will blow out the paper from a auto-type filter and the residue into the engine innards. Don't take a chance.

Oil Changes
Don't know how much motoring you do, but for the cost of a few quarts of oil and a filter, every 50 hours is what I do. Clean oil is cheap maintenance.

oil filter replacement
Brad,If it were my boat I would change the oil and oil filter at least every 100 hours if not sooner.As stated it is cheap insurance and easy maintance. As with everthing mechanical maintance is everthing!As far as the Yanmar filter is concerned,I would use it.My marina is also a Yanmar dealer so they stock the part and even have Yanmar oil.If you figure the cost for Yanmar parts vs. aftermarket parts vs years of ownership, not a lot of money.I would not be afraid to use a aftermarket filter if no Yanmar part were available but would replace it with the Yanmar when available. If Yanmar parts are not readily available in you area create your own parts supply. In short change both oil and oil filter every time and use Yanmar filters!

This subject will never go away
We beat it to death again last summer. WHAT I DO is,,,
use after market filters. As a car freak since the '50s, (I was a little kid) I have heard many opinions. It is classical, the older I get, the more opinions. Yes, for the price of a filter, if it makes you feel good, change it. If, for any reason, what YOU HAVE TO DO, is different, do it. I have heard the Yanmar high pressure spiel before. A performance automotive filter is good to 400 psi. I use WIX in all my stuff. I have things like a big block Chevy hotrod, a 4X4 pickup, a 10KW gas generator, a 4X4 diesel tractor, a Porsche (my wifes, yuck!) let me think,, oh yea, a Yanmar 3GM30F. I've had it since '86. Even rebuilt it a while back. The filter location didn't work for me. I found a remote mount at Summit Racing that uses a full size automotive filter. Works great. And because the filter is four times as large as the Yanmar size, it will last four times longer. Yes size does matter. Now I can use a $4.95 filter through 4 changes. A buck and a quarter per change, the path to financial security! Pretty silly, but it works for me. Oh, If anyone cares, those Yanmar filters for the GMs, ask for a filter for a Mazda GLC at your local auto parts store. (plus several other models)Same one.

when reading these posts and wonder how critical the oil filter is for a marine diesel. I have a Yanmar YSE8. The YS series of Yanmars (YSE, YSB, YSM) were built from the mid '70s to early '80s and they don't have oil filters or air filters (or gauges and tachs for that matter). Yet most of them are still running great today. Mine is a '75 and I know of at least 10 more in my YC alone from that time frame that are still in their original boats. The manual calls for oil changes every 100 hours. Kevin

Kevin, Amen
Did I say that? My religion is Evolution! To add to Kevins' post, Atomic fours also have no filter. But then too, they only have two main bearings.

I don't have a Yanmar, but I can tell you about Universal engine oil and fuel filters. I got tired of my local Universal dealer not stocking filters to fit my M-18. He would have to order them, I would have to wait, and pay shipping and tax to the tune of over $10 each. I took an old fuel and oil filter and rubbed the pretty Universal silver paint off with some laquer thinner. The oil filter PN 300209 is a Champion PH2808. The fuel filter PN 298854 is a Baldwim BF940. Both are common filters available at my local auto parts store. So much for OEM being better.

One of the first rules in business management is
don't re-invent the wheel. Successful companies have no intension of re-inventing something like an oil filter.

I had trouble using a NAPA filter ...
on my Universal M12 ... Kubota diesel? ... it was just an 1/8 inch too big on the outside can ... but the Fram PH3593A at Walmart seems to work OK ... at least for the past three years that I have owned the boat ... I've used the same model Fram PH3593A replacement on another boat [J30] ... for the past 14 years. No one really thinks that Yanmar makes their own filters do they? Re adding a larger filter ... when I was in the 18 wheeler business, the first thing we did was to add a bigger gallon+ filter to the diesel engine ... but then we were looking for a quarter million miles on an engine.

Re: repainted filers, it's called 'rebranding'...
...and you can see it thru-out the local West Marine store. There's a huge benefit to the business bottom line when rebranding, so it's easy to understand. E.g. WM previously (I'm estimating) netted 10% on the Shakespeare rail mount and 1' s/s antenna extension I just bought for mounting my Navtex antenna. But rebranded under the WM label (same products; same mfgr.), I would have given WM (I'm estimating) 100% profit (and I'm allowing them some add'l cost on their part to manage their sourcing). Of course, I purchased elsewhere and so neither the WM stock holder nor the customer was served well by the practice. Budget Marine's franchise in the Caribbean rebrands a huge assortment of items but they seem to know how to make an item cost less than the original manufacturer's part OR they have it built overseas for less, things that are immensely appreciated down in the pricey islands. My new Westerbeke's filters, when the red paint was removed, were FRAM units, as well. I got a good chuckle when someone else in this thread posted the rhetorical question "No one really thinks Yanmar makes their own filters, do they?" Of course not. My Westerbeke dealer just sold me a spare onboard fuel pump to take back with me; he buys it direct from a distributor and his retail price (including his profit) is $55. W's price for the same item is $117. When I beat up the W distributor down in Miami about this kind of thing - a good guy, BTW - he gets so defensive so fast that it's easy to see this issue has plagued big-name manufacturers for a long, long time.

What I try to do Jack, is pay next to nothing for
my stuff. Can guys like me pick your brain? Easy Dab comes to mind.
