Used to get19-20mpg cruising on freeway and on the same route I was getting 13-15 cruising the freeway where as before I got 19-20mpg.
Has that happened to anybody?
Experienced the SAME thing. Went from ~16-18 city and ~21 hwy to ~11 city and ~16 highway.
I'm about 1K into my new plugs and I'm almost back to my old MPG.
