Anyone have firsthand experience with either?

 

Whay can be said about either? Do they live up to the hype?

Yes, they both do. 

 

Just the Frantz no longer uses TP and have there own special filter media.  Centrifuge oil filter are expensive from the get-go to purchase but actually do filter quite well. I've have the Frantz filter but no longer using it when I figured out the TP rolls are now too short and not sealing properly. So back in the day I use to buy a large 12 pack of Scott's toilet paper for $9 bucks now you can only buy 1 filter from Frantz for $9 bucks. 

 

With either filter system I'm not liking the fact of the oil being in a simple rubber hose and rupture of the hose could wipe out your entire engine. You would have to invest in some better hydraulic lines and fitting to ensure the protection the oil system and not use simple rubber hose which is risky. 

 

At one point I was looking for a spin on solution of a bypass filter but the micron rating just ain't good enough. Frant Filter are very messy to change, the filter must be hung up-side-down to keep the mess to a minimum. Then the TP rolls typically are too big so you have to pull off several revolutions of paper and size the roll up in the can to make a tight fit. The other problem is the can o-ring would start to fail after either the 2nd or 3rd filter change. Thes are not cheap either and only sold by Frantz. 

 

Like in the early year everyone used to scream about having a pre-lube pump to build oil pressure before start to prevent bearing wear. 

 

So now I look towards all the folks that have cleared the 1 million milestone. None of them had to use any added filtration and just good ol' Petroleum oils.
