Car Forum / Ford / Ford Explorer / June 2005Mileage down
I used to get high 18s in my 2001 Explorer Sport. I am down to low 16mpg? 4.0 V6 84,000 miles Any ideas what to look at? Thanks Spark plugs/wires-MAYBE/ Air cleaner/ Air pressure in tires/ Alignment/off by just a fraction could mean the difference of tires straight on the road or dragging sideways 1/8 of every mile. Just a few but these are th emain culprits of lowered gas mileage. You didn't say if you have a check engine light on or not. Searcher1 No check engine light. Tires brand new and pressure religiously checked. New air filter......... > Spark plugs/wires-MAYBE/ > Air cleaner/ Air pressure in tires/ [quoted text clipped - 5 lines] > > Searcher1 Plugs and or wires would be my best guess then. THey are Platinum plugs and they should last 100 000, but I changed mine at 50000/ You may not like hearing this but I have a 97 Explorer 4.0 sohc with 97000. I get 19/21 city and almost 23/24 highway. "Brother, it ain't no joke". I always did get pretty good gas mileage and I have always used 87 octane, but the "secret" is the oil and filter (as far as I'm concerned that is) I use Mobile One oil and a K&N oil filter.LIke I said I changed my plugs at 50 and I have cleaned them since. Every month I will put in one bottle of 104 octane ( I feel ) It does a good job of keeping the system cleaner. I also (like you) am religious about maintenance, tires/pressure/align, ETC. A sensor could be going up (I think, don't hold me to this) and that might cause a drop in mileage, But chasing it down is like finding hens teeth, until it goes completely or enough to trigger a DTC. Good luck and let us know how it goes. Searcher1 Any tips for getting the rear plug on the passenger side? It looks like a bear. I have a hight quality torque wrench. So plugs and wires will be next. I did a cross counry trip couple of years ago and the best I got was 20mph. V-6 4.0 SOHC > Plugs and or wires would be my best guess then.

Haven't tried it yet but it is due on my 98 so post back if you figured it out.  SignatureAllan Williams > Any tips for getting the rear plug on the passenger side? It looks like > a bear.

(I did not remove the wheel just a hard left turn before I shut it off..) I did use a swivel next to the socket however. Hope this helps.

If the engine isn't heating up properly, you'll run rich all the time. > I used to get high 18s in my 2001 Explorer Sport. I am down to low > 16mpg?

You will get better mileage with plain unleaded, but around here it's 10 cents/gal more. wth >I used to get high 18s in my 2001 Explorer Sport. I am down to low > 16mpg?
