And that $2.59 is for 87 octane. :eek4:
It's $2.99 for 91 octane.
Re: o2 Sensor input...The only to be absolutely sure is to connect a diagnostic tool [or multimeter] and read the o2 sensor voltage.
That said, I doubt that the o2 sensor is the cause.
My 2.5 year average MPG is currently 26.079.
But on a single fillup, I'll usually alternate between 24 and 26 mpg.
Coming back from SEMA last year, I saw 31.8 mpg between Boron and Buttonwillow, CA.
