Ways to add MPG in a $$$ Gas Price Economy!

[DWs-TTEB]

Thanks. Napa auto parts’ website insists this won’t fit the expedition so I’ll ask a mechanic here before trying the install. I e never done spark plugs before.

Well, websites told me that too, but been running them in my engine for 500 miles now & no issues. I followed the recommendations of others on this forum that I trust.

The NGK’s are on. Gap was .034 with just over 12k mi.

Not completely incorrect. When trying to conserve fuel I drive like there's an egg under my foot. So far I'm getting over 21 mpg in stop and go. The lights drive me nuts though...I can see my mpg ticking down as I wait for the light to cycle. But it's more fun zipping around in my EV watching everyone else trying to conserve fuel.

I feel that having a Mach E as my daily driver absolves me of all responsibility for driving the Expedition in a gas conscious manner ;-)

The expedition is my economy car...

Exact same for me! Super easy swap. Heck, so much faster than my previous vehicle with 16 plugs. Only thing that was annoying was the parts were pretty flimsy, felt like you could easily break the coil packs on top or bend the boot too much getting them in and out.

Lol! This reminds me of when I was 16 and was burning gas and tires in my 69 Fastback Mustang at such a high rate that I could barely afford beer! So I concocted a wood block behind my accelerator linkage at the carburetor which would only allow me to go half throttle at best. I still managed to get up to 100 mph on a straight away that we as kids used to drag race on. Needless to say it didn’t last long because I was starting to bend the linkage trying to still do burn outs. I wound up taking on another job at a full service gas station pumping gas at nights and Saturdays. I was able to run a tab and turn over my paycheck at the end of the week for my gas and tire bills. Back then there was no 401K plan…. Just Good Gulf 89 Leaded and G-60/14” Belted plan ….The good Ol days! Lol!

How difficult is it to reach the plugs? TIA

Crazy easy! They are on top of the motor. Remove engine cover if you have one & unscrew the bolt holding the coil pack and plug boot then pull that coil/boot straight up and there’s your access to the plug.

FWIW, I've written several long range mileage reports up and down the east coast before and after mods. Feel free to research under my name for the posts.

But recently, on the same stretch of road here (no traffic back and forth mileage, several miles testing with cruise on), I saw 29mpg average at 30 mph. Just figured I'd post it here anyway.

I guess I'd have me some floor-mat omelet then.... my greatest weakness is not converting those dead-dinosaurs to obnoxious exhaust noise with some obnoxious driving.

And just to be clear, 4WD auto does burn more fuel. Whether or not one can properly perceive it, is definitely up for debate. But if we're talking maximum savings of fuel, 2Hi is better the 4WD Auto.
