I spent my young formative years turning wrenches on Fighter Jets and helicopters.
I know all about routine and preventative maintenance.
Not driving much, I've shortened the schedule for routine things like oil and trans. fluid changes.
Some of the modern oils say they're good for 10,000 miles, and maybe they are.
I think our cars say change the oil at 6,000.
I can't bring myself to that. I'm old school and always changed it at 3,000 with the old style oils of the day.
I never got out of that habit when the new synthetic stuff came along.
Another thing I do on the 1/2 schedule is trans. fluid change.
I was really dreading doing it on the 2006 F250's 6-speed manual, as it is coming up on 62,000 miles.
It holds almost 2 gallons of fluid and I have to put it in with one of those pumps you see catsup in at fast food places.
It says do it at 60,000. I got it at 30,000, and meant to do it again at 60,000 last time I changed the oil.
I finally got around to it, knowing I had another 1,000 before I was due to change the oil.
I recorded the trans. fluid change, and noticed the last time I changed the oil,,,
2,000 miles ago was March of 2021.
I know most of the problems folks have with one of these 5.4 Tritons messing up the cam phasers
can be traced back to the wrong oil or people never changing it. Even with only 2,000 miles since the last change,,,
I felt guilty for not doing it for 2 & 1/2 years.
