Wow. If you need a space for your engine to go foom maybe you should install another filter.


Sorry, I had a weak moment and couldn't resist

What, you don't have a foom filter??

Teach me to proof read better!

Thanks,

I already have fuel filters, oil filters, water filters, now you're telling me I need foom filters too? Hope they're not too expensive.

To try and get back on track, we ran two Luberfiner bypass oil filters on our CAT D330's for several years but would change the oil about every 6-9 months to maintain the lubricating qualities. The only problem was the oil was so clean I couldn't read the dip stick. Great for engine life, I would guess... Capt Phil

Don't be fooled into thinking that ultra filtration of your oil will extend the oil change interval. The oil my appear clean but the additives put in by the refiner will have disappeared and the oil will no longer do its job.

I had a 40 series Landcruiser for 22 years with a 3.9l H2 Diesel motor. I changed oil and all filters every 5000km. When I sold the car it had 820.000km on the clock and was still running.
A bit low on compression but running.
My new Landcruiser ( yes I like them ) has a Franz toilet roll filter fitted, a friend talked me into it. In about 15 years I can tell you if it makes a difference. :-)
I got one in my VW Kombi as well and they say I don't have to change the oil at all just the filter and replace the oil that got lost by changing the toilet roll.
But I can't help it and change my oil anyway.
Those filters are bypass filters and here is a link Frantz Filters Australasia
I think they are more feel good filter than something we really need.

My boat Palmer IH 392 has bypass filters fitted and use a C3P cartridge filter. Those filters are original factory install. Engines are from 1970.

Car I also have a TP filter using one of those motor guard filter housings on a car and have not changed oil in 30,000 miles. I am running synthetic oil.

The theory being every so often you change the toilet paper filter and add a qt of fresh oil.
And this keeps the additives in better shape.

It has been my understanding that engine oils do not wear out. The fact that I replace 6 quarts of a 20 quart system every time I change my GCF is more than enough to replace any additives lost. I have over 2,000 hours on my JD 4045T and every oil analysis has come back good. Below is one of many web sites that promote the use of bypass filters.

It is absolutely common and routine for trucks and other commercial diesel engines to have bypass filtration systems. It is routine for some of these trucks to go 30,000 miles between changes using synthetic oil. It has been proven that bypass filtration does extend engine life significantly in heavy duty applications. You can buy reasonably priced units right off the shelf that take reasonably priced filters. Whether or not it makes sense for your engine is hard to say. I would venture yes on a long-range trawler that depends completely on its engine and runs it long and hard. The oil savings alone will probably pay for it within a few years. You might want to get 10,000 hours or more out of that engine before it needs a rebuild. On a lot of sailboats you will probably want to be changing that oil a lot less often just because you just don't use the engine as much, and you use a lot less oil, so less of a factor on cost. Most sailboat engines die from neglect, corrosion, and other factors long before they wear out or need a rebuild, so the reduction in wear is harder to justify.

In my opinion best to change oil and filters per the manufacturers manual.

I would think a pre-oiler pump would be a better investment for most boat owners. I've read many reports that say the most where comes during startup until oil is flowing. Just my two cents, Mike.

a pre-oiler pump made using a shurflo pump
a rather interesting idea!

45 PSI setting is just perfect.

If you roll the engine over for ten to fifteen seconds with the start disabled you can accomplish virtually the same effect as using a pre oiler.

Not exactly....that's no diffent than starting it.....Pre-lub on big engines ensures there is pressurized oil in all galleries, crank etc.
