A few thoughts.

Local automotive radio show sponsored by NAPA, most those that participate are service stations, but two are also used car dealers and one is a auto leasing company. As routinely pointed out, a vehicle with an extensive PM service history is worth more than a vehicle with a “shoulder shrug” when asked. How many times do we see comments on here of people buying used trucks with no clue the service history, if you’re buying a used vehicle, which would you rather buy, one with an extensive PM service history or one with no history?

According to Kenworth, my 2021 semi’s transmission fluid is rated to 500k miles before needing servicing. My coworkers 2020 truck had the trans rebuilt at 465,000 miles, Kenworth put new fluid in and said it’s good to 900k. Few months back, he was commenting the truck shifted strange, it’s got 680,000 miles on it. Boss had the mechanic look at it, the fluid new is purplish, the sample they pulled was black. Changed the fluid, miraculously the truck shifts and cycles much better. All our trucks are now on a 250k transmission fluid interval.
