Hey Pops, its been about 6 months now since you did your full fluid change right? I did all my fluids around Thanksgiving and I'm still seeing considerable increases in my MPGs, are you still seeing steady MPG? 2-3 weeks ago I was getting 14.5mpg with just intake, tuner, fresh fluids, and of course driving reasonably, I was impressed! Prior to a full fluid change I was only getting 11.5-12ish... Just wanted to see if you are still seeing benefits in this after a period of time.
