Post Your MPGs

[nick_rabbo]

Hey all, I thought this would be interesting to see what others are experiencing. I know we don't own SUVs because we are the most sensitive to MPGs, but I thought this would be fun to see what everyone is experiencing based on their setups and age. I'll start.

Would be good to specify the method of determining both distance and MPG. The odometer in pretty much all of our vehicles is going to be slightly off since very few people here are running standard size tires.

The onboard MPG calculation is also pretty suspect.

I mostly use the odometer and filling at the same pump to determine MPG since at least even if the odometer is off, it's always off by the same ratio. But someone using odometer and the MPG display can't really compare MPG to someone using a different method of calculating it.

Even better would be using GPS to keep track of distance. I know my torque pro app can do this but I'm always too lazy to do it that way.

The optimism meter displays 23.1 MPG. When I hand calculate the MPG it’s actu about 21 MPG. I’ve only had the v6 about a month and combined city/highway I’m getting about 19.

first we would have to agree which engines we measure!

A V6 would of course run better MPGs than a V8!

As to my V8, 2UZ-FE, I have added a second fuel type with a 90l tank for LPG (Liquid Petroleum Gas). LPG is half the price of regular fuel here in Europe and the V8s usually run very well on it.

Fuel consumption is higher since LPG is less energy dense, but in Europe LPG costs half the price of regular fuel!

LPG: 20l per 100km (European) about 12 mpg (U.S.)
benzin: 15l per 100 km (European) about 16 mpg (U.S.)

I do not drive slow, although a T4R is not a race car.

2004 v6: i have only had mine a month too and reset the comp (previously 18.9 for who knows how long) and I have been averaging 21 mpg for the past couple weeks.

2007 v6 2wd. stock, 200k miles, tires @ 34 psi

The cheater computer displays 24.1 MPG LOL

When I first bought the truck I was using an iOS app called accufuel and after a few months worth of fills I was averaging 18.3 MPG mostly highway commute miles.


If I'm road tripping I can squeeze 400 miles out of a tank without too much effort.

My recent thread shows my MPG data from almost 2 years of tracking using miles traveled by the trip odometer divided by gallons to fill. My truck is a V6 on standard-sized tires. My driving is a mix of local and highway and it's fairly hilly where I live.

From that thread:

==
Most Recent - 16.13
Minimum - 13.17 (That was a full day off-road.)
Maximum - 21.18 (A full day of highway driving.)
Average - 17.48

I also used my OBD reader and Fusion app to check what the truck was reporting as instant MPG on a recent trip. I was curious to see if speed's effect on MPG was as much as it's supposed to be, and while I'm not certain how reliable the instant MPG info is, it is useful for measuring data relative to another value.

It surprised me to see 23.5 while cruising at 55 on a level highway. Increasing speed by 10 mph each time, the fuel economy declined significantly, first to around 20 at 65 and down to around 18.5 or so at 75.

oh yes, forgot to say that in my long distance trips I average btw 85 and 95 mph

Yes, its Europe, we drive a bit faster than on the other side of the Atlantic. And for that speed, weight, size + 4WD the 4Runner has perfect consumption!

A V6 would of course run better MPGs than a V8!

2005 V8, I get about 11.5 mpg. I don't know how you all break 15mpg let alone 20..

Good point. I know there's some type of conversation calculation based of tire size but I don't know what that is.

So all I did was ensured I had a full tank of gas and drove it to the last drop. Then saw how much mileage trip computer said I drove and saw how much average mpgs the center console said.

What would be a better approach? Take mileage driven and divide that by number of gallons in full tank? Which I guess still could be off since I'd be relying on trip computer reading with larger tires.

Torque pro app? I don't have that, should I invest in it for this exercise or is its mpg calculations not that accurate either?

Thanks for feedback

Do you have a heavy right foot? Have you added lots of weight to the vehicle? 11.5 mpgs seems fairly low for a 4runner. Have you done recent tune ups and stuff?

There are lots of apps that can track distance driven very accurately, but they'll need to have GPS on the entire time you're driving. And if you forget to start the app, you've lost your accuracy. Torque is nice since you can leave the app open, and it will start tracking when it connects to your ODBII adapter, so you don't have to think about it, and it knows when you're driving. If you compared that distance to your odometer for the same time period, you'd get a great conversion factor. But realistically, if you know the stock tire diameter and your tire diameter, you should be able to get a very accurate distance with just math.

For determining fuel consumed, the best way is to fill completely, then refill at the same pump, and use the amount filled.

So if you filled up, started Torque, reset the trip od, and then when you filled up again, took that number, GPS-based distance, and od-based distance, you'd have very accurate MPG and from then on know the conversion factor for the odometer.

This would also let you see how accurate torque's MPG calculation is. In the settings, you can change the MPG "trim" to compensate if it's off. Do this whole thing a few times and you can probably just use Torque and be confident in its accuracy.

14.0 mpg. But this is after I rebuilt my v8 when it exploded, so its 80% brand new parts. I would assume that this value will decrease over time.

 

[B33R_Runner]

'03 V6 4wd, few modifications aside from FJ coils/5100s and sliders. After 201 fill-ups, I'm currently at 18.35 mpg, manually calculated. Switched tires to 255/75/17s from stock size after the 95th fill-up. Best tank was 24.43 mpg (flat road trip with a nice tailwind) and worst was 9.35 mpg (trails in SW CO).

For comparison, my wife's '05 V8 (GX) is averaging 15.24 mpg after 49 fill-ups.

The GX that I just sold was getting about 16 combined. My V6 SR5 I can get 425 miles out of a tank.

 

[Shiftless Joe]

2007 V8 2wd with 140,000 on it, averaged 21 to 22 mpg from Wisconsin down to Venice Louisiana and back.

 

[The Yin]

About 15

I seem to average 15 or 16 mpg, with a balance of highway/city driving. Based on fill ups and odometer reading, which is slightly off since I have larger then stock tires.

Specs: v6, 2wd, 2/3 inch lift, 275/70 E-rated, fullsize spare, roof rack (add's maybe 50 lbs).

 

[Arik07]

I do about 60/40 city/highway. It's been less than a week but showing that I'm avg 19.7mpg. I don't know how accurate or inaccurate this is but I know these things suck gas so I typically drive speed limit +/- a few and very casually. For instance, going to work I'm doing 60 - 65mph. I'm my Corolla I'd be doing 70 -75mph.

I can get over 21 driving about 65 on the interstate. Once I push it to 70 mileage drops to about 18.

 

[williamteichroeb]

14-16 mpg, manually calcuated over many months, and adjusted for increased tire size (33.3 current tire size, divided by 30.6 stock tire size)

14 for combined city and highway. 16 if I'm being nice driving 55 mph on flat roads.

I do have an 09 V6, perfectly maintained and tuned up. But it has about 700 lbs of armour and cargo, a roof rack, 33.3" tires, and a 3.5'/3" lift on it.........sooooooooo
