I have a 2007 Explorer Eddie Bauer V8 4x4 with close to 80,000 miles on it. I have owned it since it was new in August of 2007. It still runs like a top. In fact, on the highway I still get close to 21 or 22 MPG on it. It uses no oil between oil changes. I go about 6 months and maybe 4000 miles between the oil changes.
I do have a question regarding spark plug replacement.
I understand replacing the plugs on this V8 is a very difficult and potentially dangerous job. Is there any reason for me to replace the plugs any time soon? I was planning on doing it at about 100K unless I start noticing a reduction in performance.
What have other Explorer owners of this vintage with the V8 done? I know I have low miles considering the age. If I do need to change the plugs, should I have the dealer do it? Since the plugs are prone to breaking I want someone who has plenty of experience with this. Is there a disadvantage to leaving them in as long as possible? Will they be more difficult to change?
Anyone with a similar vehicle might be able to share what they feel is the best course of action for me. Also, any other maintenance advice would be helpful since I plan on keeping this thing until it dies. It’s not worth much in value now although it has no body rust, nor does it have much of any rust underneath the car.
