Not really... I sold filters for thirteen years. For just about anything with a combustion engine or hydraulic system.
Discussions are good, till a person gets to a point that they HAVE to be right about everything and they do all they can to try and prove how right they are. I'm afraid this thread has deteriorated to the point it's no longer a teaching thread, but one upmanship at best.
Sometimes I walk away from a subject because there's not any use in trying to make someone else feel inferior. In the case of this thread, with a moderate amount of care (regular oil changes among other things) these old stovebolt engines should run many years with no oiling problems with the newer / improved oils we have now over what was available when these rigs were built.
As far as I'm concerned, if a person isn't taking proper care of the engine, it won't matter what the micron rating of the filter is. Nor if it's a full flow filter or bypass filter or a combination of the two.
I also think that if a person is taking proper care of the engine with regular oil changes, it really won't matter what the micron rating of the filter is either.
After all, if the engine is clean, the filter won't have a lot of work to do. If the engine is very dirty, the filter may not can do its job before stopping up any way.
So it all boils down to whether or not the owner of the vehicle takes care of the engine properly or not.
We can get so caught up with the small details that we lose sight of the bigger picture.
If you want to open another can of worms, start comparing one brand filter to another. Some will swear by Baldwin, some by Wix, others by Fram. But none will be any better than the other if proper maintenance isn't followed.
