I use a RACOR LFS-802. Why?, because RACOR is a major world manufacturer of filters and filtering equipment. The OilGuard is very much like a RACOR, but is not a RACOR. RACOR is built to industrial commercial standards, that is what they do, and they do it well.



The only thing I did (modify) was have a 1/4 npt bung welded to the bottom of the filter cannister so I can drain the oil IN the filter cannister before I unscrew it for filter changing. If you do not do that when you change the filter, you have a fully full filter cannister you are under looking up and wondering if you are going to give yourself an oil bath in the face.



You can get 1/4 NPT bungs from just about any good auto supply house.



When you are shopping for the bypass filter concept you want to know at what filtering level the filter filters at, and what percentage of the oil is filtered at that level.



Advertisement reads something like:

The xxx filters down tothe 1 um level. True, but it only filters 2% of the oil it gets to that level. While it filters 100% of the oil at the 30um level, but that does not sound so impressive. The ads are very tuned to marketing.



You want something that filters 100% of the oil it gets at the x um level.



Remember the bypass concept is you are only going to be filtering about 10% of the total oil flow through the bypass filter and not every engine can have 10% of its oil flow shunted off and not back into the lubrication process like our ISB's can. I remember reading a guy put a bypass filter on an import high reving engine and destroyed his engine because there was no excess oil pumping capacity built into his engine design. When he shunted 10 % of his oil flow off to the bypass filter the engine was starved of oil flow, overheated and seized over time.



There are several good threads about oil bypass filters in the TDR archives.

I have been using the amsoil dual remote setup for the past 180k with zero problems. I dont have any pics. Not sure if he is still a member but CPFF (cummins powered fast ford) His name is John Strenkowski at Tri County Machine in Lebannon Conn ( he was the guy who originally made and supplied the kdp jigs, one for each region way back when as well as the first to get the vacumn pump seals seperately).

He used to sell a billet adapter for the oil filter head to hook up your lines to. That thing is sweet. Use it in place of the one supplied by amsoil or just buy the parts seperate from him or amsoil that way you dont have to pay for parts you are not going to use. It allows you to rotate it so you can set it where you want the lines coming out. He also makes a nice pass side battery mount for it. His mount the battery is not holding the weight. If going this route it would be worth at least giving him a call.



Amsoil also makes just a bypass setup which leaves the stock filter right where it is. no idea on cost



It would also probably be worth looking at the frantz system (toilet paper one). no idea on cost

The basic litmus test of ANY bypass filter, is what it shows in typical oil analysis as to contaminant, wear metal levels and particle counts. It's easy to print sales/marketing hype, but actual real world performance is what you are really paying for - all the advertising hype and shiny hardware isn't worth much if it doesn't PERFORM!



Check out the Bypass filter forum over at www.bobistheoilguy.com for lots of detailed discussion and actual comparisons of various bypass filters.

Best test ?

Been using my Frantz now for 350k and analyze once per month, read outs always the same boring stuff. Good for continued use. Partical count low across the board with good additive andviscosty

Now THATS some serious testing. . Oo. I also like the frantz, but not saying its best. Just been good to alot of us on the TDR that have been testing. Im still interested in this one: FS2500Filter.com - A Division of AccurateDiesel.com - Accurate Technical Services, LLC They have an interesting video. . Its a pricey unit though. Still trying to find someone that will post their oil analysis after using one. .

Phil I called the folks about this unit because I was seriously considering a change. They were very helpful and we discussed my concerns with the system I have and the analysis reports that I am getting. Their response was that I most likely would see some improvement in the clarity of the oil but not to expect a large change. That the analysis numbers I am getting are "" Very good for a bypass system "" They also use the smear test on the palm and how well does it wipe off as an indicator of how clean it is. ""Analysis is good but has variables that make single test decisions hard to make for comparison. "" another qoute. I also notice on Bob is the oil guy forums that analysis is not always an exact reading ! another thought to consider. : confused:

X2 on what Barry says about John's adapter piece. . had mine for 2 rig and about 225K+ miles... great quality product !!

I got my Amsoil dual remote filter, billet adapter, and pass side battery mount from CPFF-John Strenkowski and his wife Virginia. They are my Amsoil dealers and couldn't be more helpful. The Amsoil filter setup is great. Had it in for many years with no problems. Don't know what prices are now-probably went up, but after buying Amsoil stuff and John's mount and adapter and filters I think I was a bit over $400. Can't remember for sure, though. Highly recommended.
