As a point of reference, I have driven all over the US. Mountains, plains, high altitude, sea level....
The MPG on the dash is consistently about 1 MPG more than calculated. The gallons used is consistently about one gallon less than what I put in to fill up.
So the readings for me are repeatable but not completely accurate.

Was changing the spark plugs good? Don't know until you tell us the MPG from the last tank before you changed them.

Tank before was just under 19 mpg, so it helped a bit. I usually average between 17-19, so going above 19 is a plus! Still haven't made it over 20 though...

I have a 2010 F150 xlt 4x4 4.6l with 355 ls. I just bought it with 90,000km (56,000 miles) and I'm only getting 11mpg 😩 I've had it serviced, no codes, everything is running fine according to Midas. What the hell? Not sure if it makes a difference, but I live on the west coast of Canada. Currently winter at the moment. But still 11mpg??? The sticker claims 18-21mpg. I've been driving like an 80 year old too and it has made no difference. Any suggestions?

K&N Air filters worth it
I have a 2016 F150 4x4 SuperCrew with the Ecoboost engine. Just wondering if installing a K&N Air Filter is worth it? I have it in my Acura, but have not noticed any increase in fuel economy. Anyone have any good experience with the K&N air filter?
Thanks

From what I hear, Stick with the paper filter. K&N filters restrict the flow of air and also have the potential to get oil on the MAF sensor which can really screw things up. Another thing is that paper will catch wayyy more contaminants. Stick with paper, there will be no difference if any will be with the K&N restricting flow!

My second thought is some people swear that by installing a bed cover and a $500 tuner chip it'll gives you better mileage. I know it's a human thing to defend something you just paid $500 even if it really didn't do anything because you don't want to look bad so I think that's why nobody will admit if it doesn't work but even if it did save you some fuel how much fuel do you need to save to pay for that $500 tuner?
Just my ramblings.
