145K on your mtr. I don't think it is relevant with regards to total mileage.
I am not a mechanic, but I did sleep at a Holiday Inn last night ......just kidding.[COLOR="Blue"] " I know this ", in a 7.3L PSD the oil is used to do more than just the usual duties. A/ it lubricates the Turbo, pretty important when you drive your motor like me
.B/ it is used to help the fuel injectors function properly under their high operating pressures, C/ it also is used in some way by the injection pump that boosts the fuel up to such high injection pressures.
Whew.... if these were not enough reason for concern, running your engine like I do, with a heavy right foot, will dump allot of fuel in the engine that is not always used up effectively ie. EXCESSIVE SOOT
in Race mode with my computer chip this happens regularly. My motor has been somewhat modified and I believe that the investment was worth the peace of mind it brings me, that's before we even talk about the monetary savings brought about through extended drain intervals.
I just bought this product for the above reasons and I have had it installed for about 12-15K miles.
NO REGRETS HERE !
Anyway I don't want seem like a company rep for this product , I still am evaluating it. None the less so far I have been very pleased.
This product is backed up by 3rd party independent oil analysis. This process goes like this, a baseline sample pre-installation, one sample at 5K mi, and one more at an additional 5K mi, This give you 3 samples which should indicate and reflect the status of your oil, your engine, and your improvements that have been made over time with the new filter.
This new By-Pass Filter will filter your oil down to 3 microns where the factory filter regardless of the manufacturer (I use K&N Oil Filters) only filter down to about 14 or 15 microns. There's just to much to write about and much of this info is avail from the manufacturer. I am happy with the product so far. I am going to try a modified version of the filter element with the hopes that the oil will stay the same color as the day it went in. BUT even though the oil is not clear I can feel the difference when I rub it between my Fingers, and the independent oil analysis reflects the reduction in SOOT LEVELS and the retention of the oil's protective qualities over time.
