MPG Increase!!


Recommended Posts

Posted

My truck has 37000 miles on it and I changed the fuel filter and installed champion copper plugs. My gas mileage went from 13.1 MPG to 15.4 MPG, I do about 50/50 driving between city and highway.

My plugs weren't to bad, but they all were gapped way off.

Two months ago I would average 14 MPG in my '94 and then about a month ago after absolutly no changes made by me it jumped to my new average of 16MPH (75% city - 25% highway) ???  :chevy:

Wow that is fantastic.  I changed my fuel filter out at about 120k and saw no major difference in MPG.  I have been thinking of changing out my plugs, but thinking no more.  I am definetly doing it now.  As soon as my clutch is replaced that is. :chevy:
