Why is it easier to change the spark plugs than change the oil in my EcoBoost? Are you trying to tell us something?
Did mine today. All were right around 0.037, I think one was around 0.040. I gapped them all down to 0.030. Mine were all very sooty, alighty red in color, but not that bad that I had to brush them. I only have a little over 7,000 on the truck and it will be a year old in a few weeks.
Didnt have time to test drive it, only start it. Seems to idle the same (like garbage), we'll see on my short drive to work tomorrow if I notice a difference.
However, with the small change in gap that I did, I doubt I will.
