That's what bypass filters do.

But to do it right you need a bypass filter that is designed for your engine. Don't just put anything on there.

I thing Roger Penske was big into using bypass filtration.

I remember the ole Luber-Finer products. Some of them did use paper rolls.
All were messy to service in a boat.

Most of us (near all) don't put the hours on our personal boats to need this extra equipment.

IMO; Using quality/correct products, on a good schedule and oil labs often is the best oil maintenance you can offer your engines.

One of the many reasons I chose Yanmar for my repower was the built in bypass filtration.

Those are a lot bigger than what they show for a truck.
Are they both bypass filters or is that showing one regular and one bypass?

Interesting concept, although I haven't been able to find any info on how much it actually extends engine life. In theory it sounds like it would extend engine life "a lot" LOL.
 
Re: Found this "bypass filter" on youtube. Supposedly helps engine life and oil life?

Yes they are large filters. One filter is a regular oil filter, the other is a bypass filter. The threads on the spin on filters are different for each one so you cannot mix them up. Charter boat captains report 8 to 9 thousand hours on these engines. I think oil filtration is part of it, but there are also a lot of great design factors that come into play. I can only report that I am coming up on 4000 hrs and still don't burn any oil. I do however change oil frequently.

As a former service manager, I thought it was interesting that ThermoKing used Yanmar diesels in their trailer refrigeration units. Ease of service, long life, readily available parts. So I guess I have to echo Caesar's Ghost.
 
Re: Found this "bypass filter" on youtube. Supposedly helps engine life and oil life?

The larger Yanmars are rebranded engines from Scania, Fiat, etc.
 
Re: Found this "bypass filter" on youtube. Supposedly helps engine life and oil life?

Adding additional bypass filters on pickups and regular joe-blow cars/trucks were a big fad in the early 2000's. As mentioned above, some used paper towel rolls and promised never needing to change oil ever! Probably was a dumb fad.

I think you can buy many regular spin on filters that have a built in bypass section, often called "extended life" or some great marketing term.

Lots of truck engines and generator engines like 14liter often have multiple filters with some being full flow and the other(s) bypass.

If you trust the AI: "Yes, Wix does have oil filters with extended life and bypass sections. Some of their extended life filters, like the Wix 51387, come with built-in bypass valves to enhance filtration efficiency3. These filters are designed to provide high levels of engine protection by filtering out finer particles alongside the main filtration process."

With all due respect Krush, I don't trust AI aggregated ignorance.

I recall it was the Yanmar 3TNE that was used. A favorite in small Kohler gen-sets also.
4 quart oil sump that just needed wet spit for lubrication.
Absolutely a bomb proof lil block that after 10,000 hours was disposable vs rebuilding.
Not comparable to the 6LY, 440HP with 2 oil filters.

This is not stating anything bad about Yanmar (I luv them), just two different models and uses.

Our 12V71TIs have dual oil filter mounts. Since this thread I was wondering of using a finer oil filter for one of the two filter locations.
These filter mounts use 1 ½-12 pipe threads to screw on to.
With out any adapters, there are not a lot of fine * mic oil filters for use in this idea.
Most common oil filters, filter from 20 to 22 mic.
If anybody is interested, Donaldson makes a Extend service filter @ 15mic, part #
DBL7670.
They are several pennies more expensive that the NAPA/Wix filters but I'm almost ready to hit the purchase key.
Lately, it is calendar vs engine hours between oil changes. This coming year, it should (better be) be the other way.

Any thoughts?

I have a set of 2x triple stacker Frantz available if anybody wants them. I installed them, they were kinda in the way so I went with a spin on Amsoil setup.

The bypass filters DEF make a feelable and visible difference in the oil. My oil used to feel almost gritty after a short time and was dark black after a few hours, now it's silky smooth at oil change time. It's still black but not nearly as dark.

Another plus is I went from changing oil every 100hrs to once a season. We put about 3000 miles on the boat last year so the bypass filter system pretty much pays for itself in a season by reduced oil change frequency.

Very interesting and good report.
Have you had any oil lab testing preformed?

Yes, instead of oil change I send in samples. Even after several hundred hours on the oil the reports are better/cleaner than pre-bypass filter samples with 100hrs on it.

Even at the end of the season the oil is still fine, I could probably run multiple seasons on a single change, but I feel better changing once a season.
 
Re: Found this "bypass filter" on youtube. Supposedly helps engine life and oil life?

I did the Gulf Coast bypass system on my old boat . Changed the oil when I bought it , changed the filters and topped up the oil every 100 hours and OA every 300hours or yearly. Fourteen years later during survey ,it blew better compression than when I bought it. Top up oil was about 2 gallons per side with the paper towel filter changes. The engines were 650 HP 12v71. I believe in Bypass filtration. I put the Franz bypass filters on my generators and went to q 500 hour oil changes with Delvac 1300. OA's look good on those too. ..........Pat

I have gulf coast bypass filters. The former owner spent big $$ on a nice looking setup, he was a tugboat captain and did a lot of commercial-grade upgrades like that, I wish I could have bought all my previous boats from him, I'd have saved a lot of trouble. But I can’t tell a difference, the engines run fine. I still change the oil once a year, even though in theory I know I don't have to with these things. The manual says you can go 500+ hours with them, I've just never done it.

Would you have pictures and a price?
Thank you :)
