I am getting about 17 mostly city driving on gas with 10% ethanol. Vehicle fuel economy may decrease by up to 3.3% when using E10. So I am going to try quik trip gas as I hear it is top tier and ethanol free.
How much ethanol is in gasoline and how does it affect fuel economy? - FAQ - U.S. Energy Information Administration (EIA)

I need to phone a friend (chem eng) that knows this stuff like its his job (it is lol) so I will get back to you.
Numbers are never BS but sometimes the logic behind them is pure crap.
Yes, your scenario could effect MPG but nowhere near as much as driving style, environmental conditions like time of day, barometric pressure, etc.

I like a guy who actually posts a link to data for explanation. Good work!

Rydr1,
Sorry for the late response to the Toyota octane requirements. I have to confess that after we gassed up her GX I saw this thread but I started with the last page and came forward one more page. I believe Lexus says 91 or higher. We have 87, 89, and 93. 93 is what we use. I have used marvel but my mainstay is redline si-1. The bottle used to settle out a layer on the bottom but not now. And the bottle I believe doesn't mention small amounts with every fill up. I believe a BMW, some time ago, posted that with his scan gauge? he determined that the metrics showed as little as one ounce per fill was enough.
While the jeep was redlined the hummer diffs and transfer case are but the gmc dealer did the tranny service with gm fluid.
On our '92 previa I dropped the tranny pan every year and replaced the small amount of fluid with Mobil 1 which always smelled burnt. I should've stayed with factory fluids.

We buy body on frame trucks that weigh like 5000lbs+. Then we all join a forum geared towards modifying said trucks and you guys spend all this time tapping away about gas mileage? "I get 19" "well I get 16" " Oh well I get 18.4!"
Seriously, go enjoy your truck for what it was made for... :redbrick:
To stay on topic, I've seen as low as 16 and high as 24 from a tank from the gas readout which probably isn't perfectly accurate anyway, so what, I enjoy every mile driven in this awesome truck, you should too.

The post had nothing to do with whether or not I enjoy the truck, nor was it a complaint about the fact that I'm not driving a Prius. I didn't purchase a 4Runner thinking that I would get great gas mileage. I did, however, expect to get the same or nearly the same mileage as my 2010. The fact that it's significantly worse under the same driving conditions was the motivation behind my post.

But what better vehicle to worry about mileage? The difference of 2 mph is can mean $8 at the pump! If we were moaning about 48 vs 50, that might be a reason to groan
Besides, an unusually low mileage can indicate a sensor or engine problem, or, as it turns out, a brake problem. So yeah, it's a good idea to keep an eye on your running mileage and compare to what others are getting for your model and in your area.

Sadly, the 2013s have that same emissions junk (AIP) under the hood as well. Not only that, buy my 4runner that was purchased in Oregon, complies to California's emissions standards as the 2014s.
Atleast Toyota put the AIP in an easy to access area, so when it fails in a few years, it will be easy to replace! Unlike the ones they put on the 2UZ-FE, which require you to remove the intake manifold to get to, which is why it cost thousands of dollars to replace them.
Testing is the same. The 2014 may have bumped up to the next 'class' (I think it's 200lb or 250lb increments) for applied coastdown coefficients or changes due to aero/weight.
Keep in mind the EPA numbers you see are rounded to up/down to a whole number. Click on "Download Data" link on the DOE website you posted to see the actual city/hwy numbers from testing.
2012 4WD Hwy - 21.6157 mpg = 22mpg
2014 4WD Hwy - 21.2997 mpg = 21mpg
A 0.316mpg (1.5%) change appears as a 1 mpg change for sticker you see on the lot.

When I filled the other day, the gauge said 580 kms to empty.
I then drove 680 kms, still had a quarter tank remaining and the range to empty was 110 kms, so almost 800 kms or say 500 miles.
Someone, think it might have been professor [MENTION=66316]1engineer[/MENTION], has also posted previously about the DTE and how it's calculated.
On a funner note, was recently blasting across Portugal in the 2015 M4 at speeds in excess of a month in jail when, with 80 kms to go to our destination, the warning light flashed and chimed, alerting that I had 36 kms to empty. Being the only one to ever hypermile an M4, I eased up until the DTE and DTD were the same, then hammered back on the gas. Eventually reached the hotel with 19 kms remaining. Average fuel economy ranged from 9 to 36L/100 km.
What a car.

You must have been driving the Ontario back roads doing 80kph to get that kind of range??

I've gotten anywhere between low 17's and 20-21 mpg over the life of mine. Really depends on city vs. highway driving and how much foot I use. Tend to drive pretty conservatively so I feel that helps with the higher mileage.
Truck has a hair over 7K on it. Bought 3/31/14. Have always used 87 octane from just about anywhere. No additives yet but maybe something to think about.
Fuel was always a constant worry with my past diesels and combined with the high cost of diesel fuel these days I always used additives as well.
So far I've been extremely pleased with the fuel economy I've gotten, I'm sure being stock helps a lot but still, best vehicle I've owned.

Was a mix of king's highways and 4 series. Ranged from a low of 9-ish L/100km on the 80-100 km/h stretches to 11-ish on the 120km/h stretches. Really am pleased. Running on Michelin LTX MS2, 275/55/20, and don't use cruise control. Now at 13,000 kms on the truck.
Speed, of course, makes all the difference, and I'm training myself to go slower to save fuel. A sixth gear, however, would make a huge impact.

After 15K miles my gas mileage has crept up to over 17 mpg overall (per dash indicator) with mixed city/highway. Heck, even the last few tanks I've averaged just over 18 mpg so I'm really happy.

For sure. I was only able to achieve low-mid 11s on I95 all the way down to DC in Aug last year. That included traffic thru Boston and into DC. Did 120-130 wherever I could.
However, out east I haven't been able to break 13L @ 120 since then (3 hour+ trips). The hills and wind really kill the mileage. Wish I had the flatter highways of Southern/East Ontario. I don't think going 110 would be much better in these kind of conditions.
