For the "I could never hide a by pass filter", crowd, I just went out and measured mine. It's just about the size of a one gallon can of paint, not really, I lied......

It's 4 inches in diameter, and 5 1/2 inches tall, with 2, 1/4 inch I.D. lines going to, and from it. I can see why no one could possibly hide one........LOL

I have no idea of how big the opponents think one is, but that's the measurements I just took. In comparison an AC PF 24 is 3.77 inches in diameter, and 4.21 inches tall. To summarize, it's 1/4 inch larger in diameter, and an 1 1/4 inches longer than a stock Pontiac PF24 oil filter.

BTW, I do run one on my 05 GTO, so for the notion that you just have to have an 18 wheeler to run one, not so. I don't have to mount it in a trailer to haul it behind me either............... It's nestled below the master cylinder, between the inner fender, and the left exhaust manifold. If I wanted to hide it, it would be under the front bumper, but that would defeat the ease of changing the media from the top, and not having to raise the car up.

Adding up to 8 times the engine longevity is well worth the effort of a proper filter on anything plus I don't have to crawl under the car to change oil constantly either. I can safely run my oil for years, just putting in a new roll of TP in every year or two. Last time I priced a roll of TP, under a buck even after covid jacked the price of toilet tissue up. It saves me money, time, and I don't have waste oil sitting in gallon jugs to dispose of. Another bonus, virtually zero engine wear, compared to a conventional filter.

Since we quit drilling for oil here, the price of oil has doubled over what it was a few years ago. I buy very little oil for my vehicles that have a by pass oil filter on, and though I do own 3 diesel trucks, they only are dually's, no 18 wheelers in my stable....

The Franz by pass filter is also used as an auxiliary transmission filter by some people, and a diesel fuel filter to remove sub 10 micron particulate that will trash an injection pump in a flash. Generac now includes them in all their units currently, gas, propane, or diesel to help with engine longevity. If anything sits longer than a hobby car without constant running, it's probably an emergency genset.

One other thing is, moisture tends to accumulate in engines that get run infrequently, (hobby cars, gensets). The Frantz, because the media is cellulose, will absorb up to 6 ounces of water, and hold onto it until the oil reaches a high enough temperature to vaporize the moisture to steam, or the media is changed, and it gets tossed.


FRANTZ FILTER ON 396 CHEVY, I BELEIVE ITS A CHEVLLE



On racing, the early Baja 1000 VW based buggies were not able to finish races due to the fine dust ingested during the race because VW only used a mesh screen in the crankcase for filtering oil. Enter the use of Frantz by pass filters, and the engine longevity was increased so they could complete the race. Probably about the furthest use from an 18 wheel diesel you could come up with.

That probably ruins the theory that only OTR 18 wheel tractor trailer diesels can benefit from them.........

I really don't care one way or the other if anyone on this board uses a by pass filter, or not, but the facts about them is what seems to get distorted from reality. They may not be for everyone, and I'm perfectly fine with that. I only wish I had tried them back in the early 70s when I first saw one demonstrated to me. It would have saved me some engines, money, and time. As the Amish say, "Old too soon, smart too late."
