Wow that’s epic. Have you been checking against your odo? Mine is always telling me slightly lower mileage than I’m actually getting when I do my math. Maybe you’re doing even.better!!!
hahahaha. I kind of thought that, but I've only had the car since last Saturday, and it's been parked since then. I'll keep an eye on it because I babied the heck out of it and just wouldn't go over 23.3. My 4cyl Camry spoils me. You can floor it everywhere and still average 30 haha
I want to know what you're doing to get that mileage lol. My GS sucks it up haha

Haha, nothing special really. I just go off what's indicated on the trip average meter. No idea if it actually matches the odo.
Funny thing is that I found an ethanol free gas station in Pinedale, Wyoming and ended up pulling close to 33mpg average on that fill up.

Did a 1700+ mile drive to Wyoming doing about 70-80 with the AC blasting the entire time.
Nice, you are getting 450h Hybrid gas mileage. What year is your GS? Miles? F Sport 19" or 18 Tires? I can get 29, I'll need to take a pic myself next long trip I take.

Ethanol free would do that because it would let the ECU efficiently increase your KCLV go up high, and advance the timing. Your GS also should have felt a little more Peppy!
I drive my GS mostly around town (suburban traffic and stop lights) and average around 17 or so. The car really excels on the highway, though. On long freeway trips I'm usually around 29 mpg, which I am more than happy with.

Some of the QuikTrips in the Austin, TX area offer E0 ethanol free 90 octane for a few cents more than 93 octane premium E10. I wonder if that would help my mileage? Prob better for engine parts, but Lexus manual says 91 octane minimum. Is it safe to use E0 all of the time?
When I had my 1992 NSX back in 2006 and lived in the Charlotte, NC area, some of the Sunoco stations had 100 octane race gas at the pump. Would be interesting to see the hp increase from that kind of octane.

You have to have an engine that can use the higher octane. There is an optimal timing that will produce the most power and if it doesn't knock on 90 octane, 100 will not produce more power or better mileage. Simply physics. Put higher octane gas in than your car can use is wasting your money.
My wife's long gone 2003 Honda Pilot would not run on 87 despite the dealership stating it was built for it. It would ping and run poorly. It got to the point I was putting a few gallons of 93 in with every fill-up to keep it happy.
In a pinch, I have topped off my GS tank over 1/2 a tank with 87 and the car ran just fine. 10 gallons of 87 on top of 8 gallons of 93 still is close enough to 90 to get by. Some people run their cars on 87 full time. It should run fine on that most of time until you stomp it, at which time it will pull timing to limit preignition.

Thanks for the explanation. I never did buy it b/c it was priced ridiculously high for 2006 - $5/gallon. That's normal CA gas prices today but back then in NC that was very high. Regular gas was in the mid to high $2 range back then IIRC.
Of course that was also before the commodities bubble in summer of 2008 when oil went to $147 a barrel and gas went up to the high $4 range for regular (and $5 for premium) even in the Austin TX area where I had moved to by then. Hopefully we don't get a repeat of that.

Straight 100 Octane maybe not. A mix with 100 Octane to boost the Octane and allow a high KCLV will. Especially if the KCLV was low to start. We discuss this many time on different CL forums. Its even been backed up by a very experienced Tuner. Less knock, more advance, more hp and tq will allow the engine to produce more, with more efficiency.
On your 2003 Pilot, my guess would be something was wrong somewhere? It was designed by Honda to run peak knock free in most conditions. The Dealership did not make the decision on what fuel octane to Run, Honda did. The other problem is that that's the 3.5 V6 same exact MDX motor. The MDX could do 300k, 400k, 500k miles. Honda stated for both the Pilot and MDX to run:
Fuel Information Use of unleaded gasoline of 87 octane or higher is recommended.
• Honda recommends TOP TIER Detergent Gasoline where available.
• Do NOT use gasoline containing more than 15% ethanol.
• Do NOT use gasoline containing methanol.
• Do NOT use gasoline containing MMT.
Most miles on a tank. Picture taken at the gas station just prior to filling up... took 15.98 gallons so still had another 1.5 gallons in the tank. ECU MPG was 26.5 mpg, calculated was 24.8 (396.6 miles /15.98 gallons.)
I drive my GS mostly around town (suburban traffic and stop lights) and average around 17 or so. The car really excels on the highway, though. On long freeway trips I'm usually around 29 mpg, which I am more than happy with.
This has been my experience as well. 17-18mpg around town, but for longer drives, 29 and even 30 mpg is easily doable going 75+ mph.
