An interesting fact regarding any PM program, someone somewhere at sometime defined that particular programs defaults. Drop the oil, change the filters. Based on a set time or mileage, drop all fluid because "thats the way we've always done it".
Ask many owners why they have a particular schedule and the answers may surprise you. Most say that that is left up to the maintenance supervisior. The owners day to day time is devoted to running the office, bidding jobs and working the budgets to assure there is enough work to make a profit at years end. Really!
So, let me ask, does the risk and rewards of an antiquated PM schedule benefit the owner or the routine of the maintenance staff? Let me ask one additional question if I may? Can you state with proof your PM is NOT Premature maintenance? The very practice of routinely dropping oil at a defined hour or mile, while normal in the industry, may very well be costing the company 10,s of 1,000's of $$$$ per year?
Why you ask? Because for over 27 years PERFORMANCE LUBRICANTS has provided our customers a solution to "Because we've always done it like this", and proven a comprehensive fluid managment program does provide a faster ROI "Return on Investment" than just dropping oil because its black, or time.
Modern triboligal contamination studies, even many major engine manufacturers support on-board micronic filtration as a proven device to improving oil life and extending the base additives. Of course, capturing periodic fluid samples will determine the best time to drop the entire crankcase deposts. Many times the volume per truck or piece of equipment contains 10-15 gallons of oil. And many times much much larger volumes.
If the average over the road truck changes every 10,000 miles, the average annual total miles is 120,000 then you are dropping over 120 gallons of oil yearly.
Kleenoil micro manages this lubricating fluid by continually trapping the smaller particulates >1um and thereby decrease the need to change the fluid as often. Many customers will safely extend oil life an average 5 to 8+times. The key, relying on the Fluid results from the laboratory to say when.
