Whether we see eye to eye on all things is irrelevant, this just makes sense to anyone that wants to extend their engine life as well as their oil life.
I have heard some wonderful things about the Frantz filters from people that have owned them, many wished they hadn't let theirs go when they traded in their cars. Some people had saved their filters and put them away on a shelf, and when they were reminded of the advantages of them dug them back out and re-installed them on what they were currently driving.
Pual, I know that you and I have differences in opinions on some things, but we both appreciate mechanical things and what it takes to keep them at their best. Best of all we both think the outdated Pontiac Stratostreak engine was a masterpiece of engineering compared to other engines designed around the same time. I think we both believe that it still has potential to run with most any 90 degree V8 current or from the past, that said, we do agree on that.
Anyway I never got up on the soapbox to try to make money, even though I am a dealer/or was a dealer for Frantz. The filter system is so much more advanced over a full flow system that more people should know there is a much better system out there than what the engineers came up with. The full flow system is marginal at cleaning the oil, but as most times in Detroit it was CHEAP to implement.
Just as some of the great ideas on the Pontiac engine that were good idea, but were done away with to save a few cents per unit. Gusher reverse flow cooling, steel timing gears, cheapening the castings on the 557 block (yeah is saved a few ounces, but at what cost) and the list goes on.
I know that looking at $250+ dollars seems expensive to switch oil filtering systems over just screwing on a new $5-$15 full flow filter, but as I have proven to myself the $250 expenditure pays for itself in less that 5 years in saving money on oil and filter changes. Every saving after that goes right in your pocket. When it comes time to get a new car you can remove the system and install it on your new car.
Now your saving money on oil and filter changes, but the thing people forget is your also lessening the wear on all the internal engine parts as a bonus. It doesn't show up in your wallet, but it's still there.
Suffice to say this is just a glimpse at a option to save anyone reading this money and internal engine wear. If it's not for you, just keep on doing what your doing, no need to try to run down the whole idea of by pass filtering because your not willing to try it.
Let me just say this, all the people I have talked with that have owned a Frantz system, and over the years it's in the hundreds, I have never had a former owner say it didn't do what it was claimed to. Most want to tell you their story and they have all been positive.
