Cheap insurance? I totally believe in proper maintenance. From personal vehicles to managing or maintaining fleets.
But there is zero “cheap insurance” by performing maintenance significantly ahead of the required or suggested intervals.
I mean, I’m more likely to buy a used vehicle from someone’s Grampa who changed the oil every 3000 miles. But it only shows anecdotally that he may have cared for the rig overall better. There’s no extra residual value. So hypothetically, “if” one was planning to keep the vehicle for 300k or 500k miles, there “might” be a slight decrease in wear, but at that point, who cares? Because the normally maintained vehicle will statistically last just as long.
Research on the subject I've read shows, for example, that oil additives are present and doing their job well past the manufacturer's recommended interval. There is just no upside to more frequent maintenance other than the piece of mind it may give. To some, that's worth the added cost.
You may want to check with GM and the sludging issue their cars had, and they came out with a flash to shorten the oil life monitor interval. So it's not just those of us that know better, manuf and engineers can learn from us also. This goes for filled for life fluids. So if you think you can go 200k miles on trans fluid go right ahead. Us technicians will gladly replace the neglected trans for you.
