Bought my 07 back in July with 97k miles on it, stepping out of a dodge ram hemi into the FJ I was ecstatic about the difference in mileage. Soon after I got it I made a 2200 mile road trip after a little trial I discovered I got the best performance out of mid grade mpg wise. Averaged between 20 and 22 on the highway and 16 in town.

The other day I decided to pull a spark plug just to see how they looked not wanting to trust the dealership changed them. Pulled the front passenger plug and found the gap to be .062 wow I said that's off so I went and grabbed some new plugs and changed them out. All of the were between .060 and .070 I had one at .075 whoa!!! Aside from the crazy gap the threads looked wet, is it possible that was unburnt gas because the gap was so far off?

Check out the thread this post came from:

for a compare here's the old plug. You can see it's worn compared to the new plugs the used plug measures 1.27mm
