Poor Fuel Economy - 2005 Triton 5.4L
#16
thanx again. Brought it back to the dealer tonight. We'll see what happens. Spark plugs are an issue, according to my tech. He claims to get them checked before 50K. We'll find out. Poor fuel quality may also seem to be an issue. I'll keep you posted on the outcome. These things should at least be able to live up to the sticker minimum.

Had it checked out by the dealer this past week. No codes, all is normal and the plugs look good. Filled up the tank and clocked in at 14.5 mpg. 2/3 of the miles were hwy and the other 1/3 around town. This fill up I used BP (Amoco). Today I'm also going to disconnect the neg. cable and see what happens this week. I do live north of Chicago where the majority of the stations are Citgo or other cheap brands. Construction on our hwys also causes a lot of slow moving or stop and go traffic where you could normally run at a steady speed.
