Re: Marine vs Automotive oil filters.....

craze1cars.. i recon u have it about right.. in a real world situation they all do their job in a "good enough" kinda way.. once a thing reaches the "good enough" point any differences beyond that point are purely academic..<br /><br />their aint no "best" anything.. most of the stuff we get aimed at us is much of a muchness and it dont really matter which brand u use.. it all does its job in a reasonable fashion..<br /><br />i recon its a common human need to feel u are useing the best.. but in a world where everything is pretty much the same that does cause some of us some problems thow.. he he <br /><br />trog100

Re: Marine vs Automotive oil filters.....

i still want to know what the real oil flow through the different blocks is <br /><br />i know its pretty low and well below even the "low flow filters"<br /><br /><br />tommays

Re: Marine vs Automotive oil filters.....

As long as you change yopur oil and filter on a regular basis. I have found that the type of oil and filter doesnt really matter. Synthetics, however, are rated to last longer than conventional oils. This is their selling point. But for basic use with regular maint. the store brands will do the job just fine.

Re: Marine vs Automotive oil filters.....

I thought the marine filters (especially the OEM ones) had better paint on the outside to help keep down corrosion.

Re: Marine vs Automotive oil filters.....

Love and peace to you too oh Crazed one, but . . .<br /><br />Actually, I tend to agree with you on this type of stuff. However, oil is a little different than a filter in that there are specifications that these oils all have to meet. The API ratings that go on the bottle (CL & SL currently) actually mean something. Filters on the other hand, do not have a overiding spec or organization that governs them.<br /><br />The big issue with filters is the sealing of the whole shebang between the clean and dirty sides. The critical pieces are the media (paper, rags, old socks, whatever), the end caps, the spring on the bottom and the main seal at the top. With the folded paper type they glue the paper to the end caps. If the glue allows the paper to seperate from the end caps, for example, all of the crud gets a free ride back to your engine. This can also happen if the end cap fails, so this is why cardboard is frowned on. The spring is a big deal too as it holds the whole thing against the seal. When you cut them apart all of this is pretty obvious, but you want to avoid any situation where the filter bypasses dirty side to clean.<br /><br />Most OEMs have these other guys build their filters. My experience is with Caterpillar and they use Donaldson now. They have used others in the past and have fired them for poor quality. The obvious reaction is that I'll buy the Donaldson for cheaper than the branded CAT one. The problem is that they actually build the CAT version on a seperate line because the differences are so great. CAT requires a plastic end cap with the paper actually IN the cap, no glue. Also they use a fiber bead spiraling around the paper folds, so that they can't "fold over".<br /><br />I only mention this whole thing to point out again that the guys that just sell filters, not engines, don't care at all about all of these expensive features. They want a shiny can and a good advertising campaign. Some of them are better than others, but their priority is to cheapen the filter, not protect the engine. This is why I buy OEM filters. I happen to buy OEM oil for my boat, but this is because Mercruiser has figured out how to scam me. They use a multivis weight that nobody else does; 25W40. This makes me nervous enough to get sucked in, but I get to be a little mad at them while I do it. Sorry, mini pet peave digression . . .

Re: Marine vs Automotive oil filters.....

I've used Fram filters on my mercruiser for 30 years. Oil is still relatively clean when drained and I still have good compression.

Re: Marine vs Automotive oil filters.....

Here is another study:<br /><br />

This oil filter study was originally started to determine if there was a better oil filter for the Mercruiser oil filter found on Chevrolet / Mercruiser inboard and I/O applications. It then grew to compare many manufacturers' equivalents to the AC PF1218. The AC PF1218 (and the Fram PH5) are used on a wide variety of vehicles particularly the GM V8.<br /><br />

I guess maybe I should have added to my disertation that even after all my suspicions that all oils & filters will most likely work just fine, I never claimed to know all (or ANY) the facts for sure...and I fully recognize that boats ARE different from cars. Therefore I feel I have little choice but to rely on the mfr recommendations. So I also buy Quicksilver 25/40 for my boat, and Mercruiser oil filters. It's just once a year, and my marina's gotta feed their kids, too!<br /><br />And for my cars (most GM), I do buy AC Delco filters...then again as a former mechanic I have a local parts shop that sells them to me at cost so there's really no reason not to. I also buy synthetic oil for the cars. But this is because I'm in the 10,000 mile oil change crowd (GASP!). Yes, it's true. I change my car and truck oils either once a year or every 10,000 miles whether it needs it or not . AC Delco filter and Mobil 1 5W-30. Even my tow vehicle. Rarely do I keep a car less than 200,000 miles and I've NEVER had a compression or wear problem. And the inner guts are always clean as a whistle. So...the 3,000 mile oil change is a myth...I'm starting to think about stretching it to 12,000. <br /><br />Over and out...

Re: Marine vs Automotive oil filters.....

I can't believe I missed a thread about oil filters <br /><br />Yeah -- I have to admit I spent many hours and $200 taking apart lots of oil filters so I could measure and analyze their media.<br /><br />Why did I do it? Curiosity. What did I learn? Some good brands to stick to and some to stay away from, and that some mfg'ers go for quality, some for flow, and some for filtration. Some try to compromise. I think the Merc filter is a good choice. If you want to try different, look at the study and see what's important to you.<br /><br />Mercruiser has a new filter out now. They claim high efficiency and good flow. It is about $12 instead of the normal $7. I don't have a part number or a name. It was in a black box with red and white highlights at my local dealer.<br /><br />Anyone seen them? I don't see it anywhere on their site (heaven forbid, they don't even have their new oil that has been out for almost a year on there either).

Mobil's new "Extended Performance" oil is guaranteed up to 15,000 miles. Go for it!!<br /><br /> http://www.mobil1.com/USA-English/MotorOil/Oils/Mobil_1_Extended_Performance.aspx

All BS....and seen it all....and I've seen idiots cut filters open with a hack saw and show me the metal filings. Stupid people should not breed........

Re: Marine vs Automotive oil filters.....

Thanks, Gary...I noticed that new Mobil 1 in the stores not long ago. That 15K between changes will scare a lot of people, but I see no reason it won't work. Now in this particular case, I would want to make darn sure I have a DURABLE oil filter that is also capable of going that distance without breaking down. But it shouldn't be a problem anyway...remember the good old days when auto manufacturers recommended replacing the oil filter at every OTHER oil change?<br /><br />I also pride myself in being a bit of an enviromentalist. Even though I'm very picky about recycling every last drop of used oil properly, including recycling used oil filters, a skipped oil change is yet another small way to help the enviroment and halve the oil disposal problem.<br /><br />I'm kind of curious if the fact the recent economy of oil prices escalating might start to close the price gap between synthetics and petroleum based oils. Wishful thinking, I suppose...

Re: Marine vs Automotive oil filters.....

it aint got that far yet crazy.. the oil goes that far but i dont think the filter does yet.. so they need splitting.. two filters per oil change praps..??<br /><br />there aint no universal law that links filter life to oil life.. he he<br /><br />the other factor that plays a part is how much u top up.. each top up is kinda like a mini oil change.. top up often enough and the stuff probably dont need changing at all.. just the filter every so often.. <br /><br />trog100

Sounds a lot like the Robster called me an idiot, but I used a super special, handy dandy, Caterpillar filter cutting tool that didn't leave any filings, so he must be talking to you, Gary . . .<br /><br />Oh, and I already have three kids and every last one of the little knuckleheads uses the hack saw, crap! So that's my genetics study.

Re: Marine vs Automotive oil filters.....

Trog can correct me if I'm wrong, but when I've discussed oil change intervals with visitors from Europe, most are surprised that we change oil so often. They indicate 9,000 and 10,000 mile oil changes are the norm. Our own manufacturers tell us 7500 miles but then they throw us the severe service clause which requires changes at half that mileage. Oil changes that frequently are a joke but to maintain our warranties we are forced into it. I too use synthetic in everything. On my out of warranty vehicles my changes are at 5000 mile intervals.

Re: Marine vs Automotive oil filters.....

Does anyone know who makes Wal-Mart's SuperTech filters and oil? Someone told me the oil was made by Havoline. Anyone else hear that? Also, I think waiting 15k to change oil is crazy. It's not really an oil issue, but rather a filter issue. Synthetics get just as dirty as petroleum based oils. <br /><br />I remember reading about the taxi cab test too. They used synthetics and noticed no difference in wear and tear.

Re: Marine vs Automotive oil filters.....

i spose it goes against the grain changing a filter without changing the oil.. but i think thats now the reality of it.. assuming we are talking about what needs doing as opposed to what gets done..<br /><br />trogs first rule of maintainance..<br /><br />if u feel the need to do it.. do it.. whether or not it needs doing is purely academic.. he he..<br /><br />trog100
