Right on, good choice!

Wahoo! Personal best for city driving!!!

This tank was on 91 octane non ethanol but it is still the best all city tank I've ever gotten. I changed my driving style since my last measly 36 mpg tank and I'm shifting at 3k. Bogging the car and adding throttle seemed to hurt my last tank

40.7 all city

Very nice.

I had one highway trip for about 45 miles which was for the tank of gas out in bfe. I know it added to my efficiency but it was about an hour and a half round trip so not very convenient, probably won't be going out there again

I added some MMO to this tank (6 ounces). Only 15 miles on it so far but the car seems to have better throttle response but that all could just be in my head, only the tank will tell the tale.

Some of my best tanks were with MMO in warmer weather. Tough to pin it down, though. If there's a magic juice out there, I haven't seen it (yet). I've dumped in Techtron and Gumout as well.

Testing 87 Octane Ethanol Free now. Not sure that it's worth the added cost. It's 50 cents more per gallon than regular in PA and $1.00 more per gallon than regular here in NJ (where ethanol-free can't be found). I have to drive three hours round trip to get it. Kinda stupid, but hey, I've done things that are way more stupid that that … :roll eyes:

I've tried Lucas, rxp, techron, but the MMO seems to have kicked my little civic in the butt. Even Vtec seemed to hit harder lol, but my fuel filter probably needs to be changed anyways so I'm sure it's just clearing out restriction.

Yeah my drive was about an hour and a half round trip and even then it was tedious, I don't have much free time but felt like splurging. 3 hours is commitment lol

Any updates to this?

Firehawk, How did you capture those AFR's - by what means ? Rob

Wow. Eight months. I hate to hijack this thread, but I will say a little about my HX. I do not ever remember having my car lose power on the highway or freeway, which everyone says is indicative of lean burn, but I try to maintain 55 MPH, although my GPS says that is only 51 MPH. I had been at or near 50 MPG each tank until I finally started my current job. I have driven 1,400 work-related miles since the end of September and I usually hit traffic. My tanks have been around 40 MPG since. I wondered if it was the colder weather and I realized that my tires were only at or below 30 PSI. Also, someone backed into my car, and I took off my grill block and air dam until I could pop out the dent, but I had 40 MPG tanks in October.

How have you guys done?
