I feel the bypass filter is not to extend the oil drain intervals primarily but rather to extend the maintenance on the internal engine parts of the engine. There are tons on studies from the US Air Force, Navy, many major cities etc. The conclusions are that the bypass filters do not save on...

Was your buddy's truck bombed? What was he / it doing at time of failure? RPM's? Boost? HP level? Torque level? Dyanoed? Many guys on TDR have 100,000 200,000 300,000 400,000 miles on theirs. I have only 55k on mine, but plan for 500k + and I tow heavy. Interesting, I would like to know more...

How are you getting the particle count? The lab I send my samples to said that a dark sample could not be particle counted reliably. Ideas? Bob Weis

2002 Dodge Cummins 5.9L, 50k Just added a RACOR LFS-802 bypass filter. Doing OA to determine FF, BF, oil changeout. Bob Weis

"A bypass oil filter will remove much of this soot, but oil analyses are still required to protect your warranty. The dispersants in oil attempt to keep the soot in sub-micron particles which are often too small to filter out even with a bypass filter. It is when the soot particles agglomerate...

At times I have seen that an oil analysis is reporting ISO Code(3) 15/14/12 or ISO Code(2) 15/12. What do those analysis numbers mean? Where can I learn more about ISO Codes? Bob Weis

Interesting concept, How would one find out the excess flow rate of their engine? (Cummins ISB 2002) Bob Weis My RACOR LFS-802 flows 1 quart / minute hot idle @ 40 psi advertised at 1 1/2 quart / min.

I am doing a RACOR LFS-802 string wound. Not much milage yet. I am testing flow rate to tell me when to change the element. Flows 1 quart / 54 seconds new. Bob Weis

Just bought a RACOR LFS-802 for $139 (incl a filter). Bought 1 spare 802BFS at $25. South East Power Systems, Orlando. Interesting comments of availability. Bob Weis

I just installed a RACOR LFS-802 bypass filter on my 2002 Dodge CTD. A cartridge, but not a spin on. RACOR because they are experts in industrial filtering and Parker-Hannifin has been around for a long time doing what they do. Advertised as 1 micron. I do not know if absolute or not. Using...
