This is a two part post. The first question that I have is about storage. Another recent post on here got me wondering if the maintenance that I'm doing on my Explorer is adequate for storage. So the Explorer is used as a road trip vehicle and is used about one week every 1 - 3 months. But when it is driven, I typically put on about 2k - 3k in that time. In the past year, I've racked up about 20k miles on it. My main concern is that it sits for such a long time in between with no use. I've already developed flat spots on the tires. I try to start it every week or two so the battery doesn't die. I have had a few messages in the past from the Ford Pass app letting me know that the truck was going into deep sleep mode. What kind of preparations should I do to keep it for storage? The other question that I have is if anyone has changed the PTU fluid on these vehicles with the 3.5L Ecoboost and the temperature sensor attached to the fill hole? It's really tight in there and to remove the temperature sensor involves removing the cat.
