Not my experience Frenchy, on my 2020 Ranger, navigation works well. The map is getting a bit out of date but not enough for me to pay for the update yet.
This morning Firefox would not let me log in. Said the site was not secure. Working OK this afternoon however. This is not the first time this has occurred with me.
11,539 miles on my 2020 Ranger purchased on Dec. 14, 2019. Oil and filter every September and tires rotated every 5,000 miles. Widower with 2 other vehicles, plus being retired, results in low mileage.
Welcome to the forum Michael.
Your truck, do what you want. However, I think all that is unnecessary. I would change the factory oil at either 5k miles, one year, or when the dash tells you to.
