Lie-O-Meter
I have seen plenty complain. When I checked mine it was almost 2 mpg off. That made me change spark plugs. Several were out of tolerance but all looked good. I gapped all the new ones to the minimum tolerance so they had room to grow as they wear. Now my Lie-O-Meter is incredibly accurate. In both MPG and gallons used. Makes me wonder.....
Do you think Lie-O-Meter can be used as a gauge for spark plug replacement? How bad are your lying and how many miles do you have on your plugs?

My 2015 F350 has 7000 miles on it and I am always quite taken by how close that computes the gas mileage. Its always withing or less then one mile per gallon off. my truck gets crap for mileage but I dont care about that and didnt purchase it for mileage

On my '11 6.2 it is optimistic by .2 to .5 mpg. There have been a few occasions when it was pessimistic.
I don't record the lie-o-meter number but I look at it while I record every tankful. That does make what I say anecdotal.
Edit: 66K miles on the beast.

The higher mileage accurate lie-o-meters make me feel good. I am really hoping to never have to change the sparkplugs again.

Any truck the 150/1500 series motors are built different than all heavy duty trucks. That why there is a dramatic difference.

I found this OOPS, in the tools section, under spark plugs.
Figure 4. The plug on the left is covered in deposits and will not work as well as the new plug on the left.
This should read "As well as the new plug on the right".

Ive never seen more than 13. Avg 10-12 mixed driving. 60K on an 11, 6.2, super cab, short box with OEM plugs. Maybe I should start doin the math to see if my lie-o-meter is truly lieing.
