Changed my Plugs this weekend with Interesting results

Not sure if it needed to be done as I have only owned the GC for a little over a month, however it was running a little rough at idle and in gear. Decided to pull the plugs and replace them with some NGK Iridiums. The plugs I pulled were run of the mill NGK's and looked pretty new. Decided to do the change over anyway and after 3 days seems my fuel economy has gone from 15.3 to 15.7. Interesting.

Re: Changed my Plugs this weekend with Interesting results

The placebo strikes again!

There is SO much to fuel economy (as told by the EVIC) that .5 mpg is great, positive results are awesome but, well let me put it this way, with my 32" tires, my first tank of gas I pulled 14.12 mpg (calculated, NOT including the additional mileage driven but not counted due to taller tires), That was an entire tank of gas. The very next week I filled up and calculated 13.1mpg (again not calculating in additonal miles). All of that to say, a typical week with no major abnormal driving (other than less babying) I was down an 1 whole mpg. A couple clicks on the evic after 3 days wouldnt have me excited yet

The ONLY mileage that can be gained with new plugs is the mileage lost (if any) with old plugs. Same goes with "performance gains".
