oil filters

[WMcGuire]

I don't usually comment on opinions but was looking for some info about other brands, locally I was able to get a WIX filter in an emergency, and have order in from Genos for the Cummins filters, not a big price difference, but first, the word "Filter" dosen't really apply to full flow "Filters", they are nothing more than strainers, filters remove contaminants, full flow strainers just stop the big harmful objects from damaging the engines, I doubt there are very many owners here that remember that oil filters were once options, vehicles came from the factory without them, I had a 61 Dodge slant six p/u without a filter, was still running strong at 125000 miles when I sold it and the engine oils weren't near as good as now, if a full flow actually filtered it would soon plug up, I once used a 'lifetime' cleanable sintered bronze full flow filter, it soon plugged to the point of plugging up and couldnt be cleaned, that was in a early Ford engine without a bypass valve, the oil pressure gauge kept rising but the engine was starving for oil, resulting with higher engine temps, luckily I caught it before too much damage, but as to all the hype about filters, it's mostly hype!

Anyone ever tried or looked at the Fleetguard LF 9028? Supposed to be a full flow and bypass all in one.

It's listed as " for Komatsu only". I talked to them a while back. Shadrach

And I disagree with your statement on the systems. The systems would have to be of difference size/volume since pressure = flow x restriction. So if you have the same pressure and different flow you have to have different restrictions.

What units are you using for restriction? I've never seen that equation before, and I'm trying to understand from where it's derived. Looks like restriction needs something like [g/(s*ft)].

That equation is Ohm's Law.



Pressure (Voltage "E")=Flow (Amperage "I")x Restriction (Resistance "R")

Two points:



If you are using the stock oil pressure gage to monitor things, keep in mind it's just a show put on by the computer and has little to do with the real world. If your OP really changes, it won't reflect it ~ note that the sending unit is just an open/close switch.



Cummins eng's don't suffer from "sludge" and dont have oil related failures as a rule. Fleetguard filters have been used on many high mileage B eng's for a Million plus miles w/o problems.
