Dear all
First I would like to thank all those working here in this forum to help others like me. I used to be an owner of of a honda accord and my dream was to by a big SUV but cash was an issue. I saw an add for a 2010 explorer for sale and luckily had the money but I was a bit skeptical about the condition of the car but after checking it out I decided to buy it as it was in a well taken care of condition. Since I was a 4 cylinders car user and now shifted to a 6 cylinders car I did not know much about its car consumption until yesterday when I was talking to a friend who happens to have a 2019 explorer where I realized that a tank shall last for about 337 miles wile mine only makes 155 Miles per tank. I was shocked that is is down to half. The car is running perfectly but inefficient.
My request to the experts here can you point me to what needs to be checked and or replaced to be able make the explorer more efficient as you know gas prices are getting higher and higher and mechanics are never honest and they try to squeeze every penny out of your pocket.
2- the other issue that I need assistance with is that my car computer broke and I replaced it with a used one where I had the other reprogrammed and everything works fine except one small thing. The car battery comes in even though there is no problem with the alternator. When I click on the reset button inside the car the battery light turns off but after 10 min it would light up. Any hint would be appreciated and thanks again for your assisyance
Hi, just wanted to start by saying thank you for your support and involvement in the explorer forum. Congrats on your brand new-ish 2010 exploder.

First of all congrats on your brand new-ish 2010 exploder, they are definately loved by many. Secondly, if you have a 2010 and you know someone with a 2019 that is getting better gas milage then that's 100% normal. As we drive our vehicles day in and day out we break them in and build up all sorts of junk slowly into our intake manifold, air intake housing, heads, valve pans, block, etc.... so the difference may be as simple as a dirty fuel filter or air filter, or as massive as sludge build up in the crankcase and major build up in the valves, rods, pistons, heads, intake, mass air sensor, 0² sensor build up, etc... I would honestly say that if you are getting 90% or better fuel economy of what a brand new 2010 explorer with that exact same engine, model, etc ...calls for directly from the manufacturer then you are probably not going to increase the fuel milage of the vehicle by much without adding aftermarket fuel savings parts I have a 1998 Ford Explorer 5.0L v8 302 that's 2wd stock and I only changed the rear end to a 3.73 and put a K&N air filter insert into the air filter box (meaning I didnt put a whole new intake tube and box and filter kit in, just the filter swap) and I have a 3" body lift and a 3" suspension lift running aluminum 16" Mickey Thompson classic 3 style rims and wrapped them with 315/75/16 tires or "35's" and I still get about 14 mpg in the city and right at 15mpg on the hwy. I beleive the factory specs say it should get 14 city/ 16hwy I THINK! Not sure tho...all I'm saying is this, change the cheaper things first to ensure you dont just have a dirty air filter or a dirty fuel filter, take these few things into consideration and change them or check then to ensure your covering all bases first before thinking of using mod chips or enhanced fuel saving performance parts....ALSO, MAKE SURE YOU CHECK THE DIFFERENCE IN FUEL TANK SIZE BEFORE DETERMINING YOUR MPG'S. A 2019 MAY HAVE A LARGER FUEL TANK THAN A 2010. THE 2010 MAY HAVE A 15 GAL WHERE AS THE 2019 MAY COME STOCK WITH A 20-25 GAL TANK.! Below I've listed a handful of parts to check, clean or change to ensure your exploder is operating at its peak performance (assuming you dont have an internal engine defect or damage causing the fuel mpg lag...)
1.) Fuel Filter
2.) Air Filter
3.) PCV Valve
4.) Oil & Filter Change
5.) Serpentine Belt
6.) O² Sensors
7.) Catalytic Converters
8.) Tires & Proper Alignment & Alignment Parts
9.) Proper Tire SIZE
10.) Mass Air Sensor
11.) M.A.P. Sensor
12.) Idle Control Sensor
13.) Intake Cleaning
14.) Axel Diff. Fluid Change
15.) Trans. Fluid Change
16.) Timing Belt / Chain
17.) Spark Plugs & Wires
18.) Compression Check
19.) Fuel Pressure & Regulator & Pump Check
20.) Check Pullys On All Belt Driven Parts
21.) A/C Clutch & Pulley Engage/Disengage
22.) All Hubs & Spindles & Bearings
23.) Air Intake Tubing & Housing
24.) All Relays & Fuses (Ensure Everything Works Properly And Isn't Underperforming)
25.) Bad/Old Fuel (Or Dirty Fuel Tank)
26.) Vacuum Advance Line & Tubings
27.) Alternator & Battery
28.) Fuel Rails & Injectors
Etc... Any or all of these things and a bunch more internal parts can fail or be performing poorly due to wear and maintenance. If you go thru these things and check and clean most and replace the things that are sensibly affordable then you should find the culprit behind the mpg lag. Good luck and congrats on the new ride, hope you figure it out soon and it ends up being a great vehicle for you as mine has been to me. It's sad that my wife's 2009 Dodge Avenger has had a busted A/C and already needs multiple things since 2017 and my 1998 Explorer still has cold A/C and is always ready to go no matter how hot or cold the weather is, they heat will suffocate you and the A/C will chill your bones and its 22 yrs old yet our 11 yr old car has had a bad suspension, A/C and overheating problem since it was 7 yrs old or so. They just dont make em like they used to, and that's a fact. Good luck and I hope you figure it out and it lasts forever.
) then after the discussion with the friend I realized that the car can do better (surely not compared to 2019 model). So I did my search and stumbled upon this great forum and read some threads where it says that this car shall give (in worst case scenario) 12 MPG and that is when I started this thread to get the help of the experts.
