Finally changed the spark plugs in my 2020 Ranger @ 120,6649 miles on the original plugs. Thought for sure the plugs world have looked worse then they did. I do have to say, the engine feels more responsive with the new plugs.

Usually I would have changed them at around 100,000, but because my truck was running so well, I just kept putting it off. I was still averaging between 23 to 24 mpg before the new plugs. I honestly thought the old plugs were going to look like crap.
I just recently changed the rear diff oil, 118,000 and the oil was still very clear, just a hint of black color in it.

I'm more shocked that the rear diff oil was still clear. On my '19 I had it changed around 25K and they said it was dark and nasty looking.
