Anatomy of a Frantz toilet paper bypass oil filter

[R C Cola]

Frantz

I have had mine on the truck for 250K and have the analysis sheets to tell me how happy I am. I also would like to make it even better because I am mever satisfied but in the mean time my oil is cleaner than most. R C Oo.

Steve, if the Amsoil unit is anything like my Frantz, the benefit will definitely be most evident out at steady speed on the open road - that's where you are most likely to see your oil get significantly clearer as the miles go by.



Good luck!

Gary... you were correct in the highway driving causing the oil to appear better... it looks completely transparent now... it is still a dark gray, but at least it doesn't look like tar...



I am very happy with the setup... I just got to get a oil pressure guage on it now...

I'm not going to read though all of this, but I just wanted to mention that I bought a Frantz filter the other day. Hasn't come in it though.



Got it off eBay for $120 shipped. That was for the marine version. The regular version is a few dollars cheaper.



I looked into the Amsoil unit, but after I priced out the cost of the filter elements, I changed my mind.



Gary, do you have any better pics on how you mounted it? Off the battery tray, or? With it being there is it in the way to get at the normal oil filter?

I believe ther are pretty good pics of the mount I made somewhere in this thread - and others in a similar thread on the Frantz fuel filter I am also using - you'll have to do a search for that one.



There is no problem doing oil filter changes from topside with the mount I made and use.

How do you not have any drips?

Well, I changed my filter the other day after letting sit overnight and there was some spilled oil. It didn't pour out, but I did lose about 1/8 a cup when I pulled the top off? What did I do wrong? Mine is mounted on the passenger side right beside my aftermarket air filter.

You probably didn't do anything wrong - I rarely have any oil drip outside of the filter base itself - but am wary enough to always place a drip cloth around that base just in case!





And for guys wanting more info on the filter mounts I use for the oil and fuel filters, here's a pointer to a thread than includes mount pics and info:

I was curious with running the return to the valve cover, is it possible to put too much oil to the rockers/valves, etc? "flooding the valves"??

I doubt it very much with the limited amount of volume you are actually returning to the valve train...

Gary,



If I remember correctly you were checking to see how many miles you could get between oil changes. How far did you get, and why did you finally change your oil?



Thanks

I went 20,000 miles on the Delo 400 - here's the final Blackstone analysis of that test:

I changed oil at that time because regardless of the analysis, I sorta hate DIRTY looking oil, and mine was getting pretty dark even with the Frantz bypass filter!

I've settled on using 12K mile, or 12 month changes - I can keep the oil pretty decent visually in that scenario.

You change the Frantz every 2500 miles? I was thinking of that and the engine oil every 10k

The frequent changing was the only reason I went with a spin-on Amsoil filter... they boast a longer change interval.



I'm not as brave as Gary, but I'm also not having analysis of the oil done either... I'm going with a 7500 mile oil and filter / 15000 mile bypass change schedule... might squeek it up to 10K/20K, based on what I'm seeing now... the bypass filter was a really good upgrade IMHO... I think I have just over 5k on it now and the oil, while dark, is still transparent!

[Gary - K7GLD]

I normally ran about 5000 miles per oil change in the past, with a TP cartridge swap at mid-point.



The 80 cents for the TP cartridge, plus about $1. 60 for the makeup oil was pretty trivial in comparison to the filtration benefit - and hell, now that amount wouldn't even pay for a gallon of diesel fuel!



BUT, the oil is still so clean at that mileage, it makes economical sense to go the 12K route - at least I'll give it a try and see how things look.

Gary is brave. But he used proven products and checked his results frequently along the way with analysis. What he has done is present us with some very valuable information by sharing his experience. If I'm not mistaken, he had some fun along the way. The data presented is valid proof that Delo 400 continues to be what it has always been, an outstanding product at a great price. The value of the Frantz filter is apparent as well. Thanks for sharing this with us.

 

[Nate]

2500 miles is not a big deal for me.



So with the Frantz taking 1 more quart, do you still only put 12 quarts at the oil change? I know they say it's only 11 quarts, but my dipstick reads in the middle of safe with 12.



I remember my Dad used to carry the stuff to do an oil change with him, when he hit 3000 miles, he'd pull over and change the oil on the side of the road He drives 100 miles a day to and from work.





The other question... with the oil dumping into the valve cover, does that pose a problem with basically flooding the valves with too much oil? It's too bad that to pull the pan is such a hassle because I'd probably run the line to the pan otherwise.

 

[fortunate1]

Gary's thread relating *his* experiences convinced me to give the Frantz TP filter a try. I wasn't disappointed in the results. I use Delo 400 also, after a brief stint with RP, and change the TP @ 3000 miles. All filters and the oil get changed at 15,000 miles, so I'll change 4 rolls of TP and add 1 gallon of fresh make-up oil from start-to-finish on each "oil change". My oil definitely stays cleaner, but does eventually darken towards the end of its duty cycle. BTW, it takes less than 10 minutes to: get everything needed for a TP change off the shelf, change out the old roll for a new one, button everything back up, add 1 quart of new oil, and put stuff away.

It's a rather small stream and volume of oil being returned - hardly enough to be any sort of drain-back issue. I seriously doubt there is any related issue to be concerned about with this, or other similar flow filters.

With due respect for you as well as any other person using a toilet paper by-pass system, anytime you add makeup oil to your system, you are putting back additives into the oil within your engine, and the oil analysis reports are going to be skewed to some degree. "One gallon in 15,000 miles" is quite a bit of oil to be adding! I have people running 20,000 miles with regular filtration (NO BY-PASS) that are getting good results back from oil analysis.
