At least the next fill (if I can get a good fill again) will be way more accurate than this one because this one is garbage.... but I'll put it on anyway. For science! The display read 45.5.mpg.

** ADDED NTK24301 OEM O2 SENSOR **
Improvement is pretty evident. I really should have splurged for the OEM in the first place. Originally when I got the OBDII O2 sensor a couple years ago, I got the Bosch, which was complete rubbish. I put the original back in and just got slightly worse mileage as I started troubleshooting other things like the EGR plate and the EGR valve (replaced that too), and a new sset of plugs. None seemed to have a noticeable effect like the OEM O2 sensor did. Now it seems to more easily enter lean burn."

This fillup was 91 octane ethanol-free gas I found in Malone NY to fill up before entering Canada. The next fillup should demonstrate dramatic increase in FE. I was shocked at how dramatically FE improved (~60 to ~73) and how much more easily I entered lean burn even on a half-tank mix of regular ol' e10 and ethanol-free. I'm extra curious to see how a full tank of non-ethanol gas works. Here's my back-of-the-napkin ""is it worth the extra price?"" calculation:


73 m/gal 3.59 $/gal 35.90/tank
60 m/gal 3.13 $/gal 31.30/tank $4.60 more per tank

130 more miles per tank $4.60 more per tank

If I went 130 miles more on low-octane gas at 60mpg, it would cost 2.16 gallons * $3.13/gallon = $6.78. Non-ethanol/ 91 octane gas is worth the price."
