Doc,
Change the filter then you can advertise your boat if you sell as having "changed oil and filters every 15 hours"!

A bit off thread (wow, I've never done that before) but years ago I read that Dr. Ferdinand Porsche (Porsche and Volkswagen) never changed oil. He believed the filters should be changed often, but the oil never broke down, so he just did the filters.
I'm a little skeptical of this.* The early Porsche and VW*engines*didn't have oil filters.* All they had was a screen in the bottom of the engine case that was to be washed out with every oil change.

I don't remember the first year they were added but it was sometime in the 356*C series which is 1963 or so.* The filter was a canister mounted on the fan housing with a replaceable element.* VW was a bit later.* The 914 was the first Porsche four cylinder that had a replaceable filter underneath the engine*as we have today and that was in*1970.*The*VW Type III had a filter similar to the*914.*

The 911 always had a filter but it was a dry sump engine*and the filter was in the right rear of the engine compartment near the oil fill cap.

When Porsche finally got its own crankcase (3 piece) (instead if using the VW 2 piece ) there were fittings for a remote filter.

Most owners installed bypass filters , as an add on.

Years ago I had a Model A. It*had no oil filter. Ferdinand had nothing on Henry.

The gas tank was in my lap with a floating sight gauge that stopped bouncing when the tank*had 2 quarts of fuel left. Oh for the good old days eh FF?*

The three piece crankcase was introduced*in November of 1954.**But there were filters on 1953 cars from the factory (verified by parts books)*and before that they were dealer installed*Fram, H*and later*Mann.

Most owners installed bypass filters , as an add on.

They were bypass and only filtered about one third of the oil.

Interesting is that the current outdated law about shutting you car before fueling it comes from that design.* The fumes would drop down and enter the magneto then go boom.

Hardly a problem on the cars of today.*

Feel the whiplash as I jerk my post back on topic and say that all of you who thought I was cheap for not wanting to change a generator oil filter with 15 hours on it can rest easy. It is changed.

What is an oil filter made of?

I was not misinformed. No one had ever informed me...so I guess that I was uninformed, which borders on ignorance, which is no excuse under the law but I will plead it anyway.

After Keith posted the picture that showed the insides and I saw paper I made up my mind but didn't want to tell anyone because I wanted to see how far off track this could go. Now I know VW's, Porches, Germans named Ferdinand, floating sight gauges, Models A's, Americans named Henry, and FF's wisdom.

I wonder how many micros oil filters*come in*and which size I should*use.

"I wonder how many micros oil filters come in and which size I should use."

The choice was made by the engine mfg , Full Flow is common , and bypass is an option to be added.

Bypass is most worthwhile keeping expensive (synthetic ) oil for longer periods of operation.


Since most yachts will seldom go the hours synthetic can bring , why bother.

Dyno oil is better at rust prevention, more important to the 200 hrs a year boater.

Consumer Reports believes "first pass" is most important , and chose Fram after their taxicab tests..
