Quote:
Hart began researching oil, oil additives, and filters in an attempt to reduce downtime. In 2010, he began making changes. The fleet purchased an oil analysis machine, switched to extended performance oil filters, and began using full synthetic oil. This allowed the fleet to extend filter changes to 10,000 miles and oil changes to 30,000 miles. Previously, it changed oil in pursuit vehicles every 5,000 miles and on administrative vehicles every 7,500 miles.


Looks like some great results in terms of reducing waste, and achieving higher ROI. By removing the emphasis from "changing" the oil, and doing proper maintenance/monitoring in other aspects of the engines, they are achieving higher overall reliability than maintenance regimes that were obsessed with the relatively short manufacturer-recommended drains.

Wonder if people would start using oil analysis if the option was stocked prominently in the oil and filter section in the stores or will way more education be needed?
I know the farm tractor dealerships have them and changing oil on tractors can be a drum at a time project so a few bucks to check before dropping could be a major $$$$ saver.

Doesn't talk about other efficiencies of doing less oil changes. Any head count reductions?

Highly doubt it in a gov't operation.

Some other maintenance or check items might suffer between extended oil changes. Do police officers check under the hood or tire pressures before starting a shift?

Probably will need a new engine at the 30,000 mark from not adding oil. Maybe not when new, but once they put some miles on and the engine starts burning oil.

Maybe, maybe not.

Sounds like snake oil to me, but then Hart will see that some miles down the road when he gets sacked for having ruined a bunch of engines for lack of maintenance.
Not even EU drain recommendations extend to 30K and they don't expect 200K out of an engine as a North American fleet operator does.

Saving time on oil changes? What do they take, 20 min tops? And that's every few months. Spread out over time that's seconds per day. You could easily regain that time by more efficient driving and routing including watching mpg, traffic control, optimized break and lunch periods, better communications, etc. The oil change is not the problem. What the staff does for 8-10 hrs/day is where things could be trimmed. If you're paying officers overtime for oil changes they're best served by taking their time on them...and being "thorough." Why can't they be done during work hours where head of the line privileges at the Lube Center could be arranged.

If they are monitoring the oil properly there is no harm. I am more curious as to what additive they are using.

The change in oil filter results in replenishing the TBN as well if they ate topping up.

There is a note about viscosity drop which means it's not oxidizing and thickening like you would see in oil that is getting close to the end of its useful life.

10K filter changes, 30K oil changes? Sounds a lot like microGreen filters.

This whole thing doesn't even make sense. How could they possibly run 30,000 mile oil changes when they don't even shut their patrol cars off when they're on their lunch break?

I read the same article with some interest last week when it came out. The payback on the oil analysis equipment is real long though...... I almost felt that they were trying to justify the investment. Good though to keep trying to find the line of waste of resources and time.
