I never change my oil on engines I have Frantz filters installed on. I've been using them for the last 50 years so I've saved a lot of cash.
One thing you may want to to consider concerning the oil return line is that it's better for it to drain downhill from the bypass filter. That way it's a lot less messy when you open up the Frantz IF you allow it to drain out the excess oil overnight.

Thanks for your reply. smile The reason I wanted to return the oil in the oil cap is so I can remove the filter with little fuss and return it to stock when I sell the vehicle. My plan is to move the Franz to each new vehicle as I replace the vehicle.

Several questions for you:
1. For the filter change... if the Franz is mounted high, will the oil drain out the intake line if parked for a few hours?
2. Is puncturing the oil pan the best way to return the oil downhill? Any other suggestions?
3. Any results to post regarding using Franz in your cars for the last 50 years? (subjective opinions are fine.) smile

1. Any drainback in the oil pressure line would be very minimal.
2. Some dislike puncturing the oil pan for the return line but I prefer returning the oil directly to the oil pan. I've never seen a problem arise from this practice. Options include using a hollow bolt. When Frantz was owned by SKY, hollow bolts were commonly available through SKY. On many engines you could remove an intake manifold bolt, replace it with the appropriate size hollow bolt and then attach your return line to the hollow bolt. I've even welded steel fittings on some of my oil pans.
3. Other than saving a lot of money on oil changes and keeping the oil and crankcase clean 100% of the time, I once had a catastrophic failure where I lost all my rod and main bearings on a 2000 Subaru due to loss of oil pressure caused by a combination of the bolts retaining the plate on the rear of oil pump and my use of a sandwich adapter. Take either factor out of the equation and I'm sure the failure wouldn't have happened. Needless to say I'll never use or recommend the use of a sandwich adapter again plus using a sandwich adapter, the oil will not drain out of the Frantz back to the pan making filter changes very messy.

Thanks for responding. I read about your problem with your Subaru in one of your threads. That is a bummer.

Now to get a unit purchased! smile

The reason I said "don't have high expectations" :

https://www.bobistheoilguy.com/forums/ubbthreads.php/topics/3658829/all/Bypass_wizards_check_in,_Cat_1

Yes, a bypass filter will help keep oil cleaner - THAT IS TRUE

The facts: having a bypass filter doesn't mean the engine will last forever.

Period.

Over 1,000,000 miles with only one oil change and No measurable internal wear using a bypass oil filter!

See http://www.gulfcoastfilters.com/1%2c000%2c000%20MILES.htm

With a testimonial like that, I would have high expectations.

Whooo! 1 Million miles. That is amazing. I do not expect my vehicle to come close to that (nor would I want to drive the same all that time... variety is nice). What I do want is quality of life for the engine... meaning low oil consumption, no blue smoke at start up, etc.

I bought an used Franz filter. I will need a new base gasket. I looked on the Franz site, and they sell them in packs of 10. I am not really interested in having that many unless they do not last long. Is there another source of gaskets anyone is aware of?

Is the o-ring style or is it the square o-ring?
The old o-ring style doesn't last very long.

I buy mine from McMaster Carr. I believe their minimum is about 25 BUT they're a lot cheaper.

I don't have it yet. Looking at the pictures I am pretty sure it has a square o ring.

You might want to give Ed Greany an email, he sells the seals for a reasonable price. I bought a 10 pack off him for 10 USD and I have only used 1 so far as they never seem to leak. His email is: [email protected]

I'm a big Frantz fan, but what about Trasko? I have been interested in them a long time but don't need to make trouble where there was no trouble by using one. It threads right on, done. I can't quite understand their logic about how it works. Being designed by, or with help from Subaru, is a good plus for them. No one has used them here?

Huh! That is new to me. That would be easier to set up as no plumbing of a separate bypass filter. And the price is cheap if it is in USD. Anyone have experience with this?

Hi A310, thanks for the information. Since you have more than you need... would you be willing to sell me a couple gaskets? I could stick some money in an envelope to you or paypal.
