MPG on your 3rd Gen?

[Shibby!]

I just completed a round trip dash to the midwest and back. Started in Spokane, WA, and ended the first half in Red Wing, MN, along the Mississippi River. Three days later, reversed the route and came home. Total distance 3,232 miles. Driving time one way 26 hours behind the wheel. I tried to keep it at the posted 75 mph interstate highway limits at all times (lots of roadwork slowed me down though). In MN, lots of secondary roads, in-town driving and interstate 90 at 70 mph. I checked the speedometer with a GPS system to insure maximum legal speeds. Tires were 265/70R16's. I had a rooftop tent mounted on my '97 SR5. I used the cruise control to help maximize the mileage.

The best mileage I got was in eastern MT with a very strong tailwind; 22.3 mpg. Worst coming home, crossing NE WY (Buffalo to Sheridan) 16.8, into a strong headwind and thunderstorm conditions. Overall average mileage for the total distance was exactly 19.0 mpg.

I am guessing that if one had a lighter foot and kept the maximum highway speed down to 60 mpg, one could easily see 22 mpg.

I average ~18 mpg on gravel roads in 2WD. In 4WD, my average fuel consumption drops dramatically; down to ~14-15 mpg. Your mileage may vary. :naughty:

I would think your roof top tent exponentially dropped your mileage with the 75 MPH.

If you were to lose the tent (I assume you used it to save accommodation costs) and went around 65 MPH, you'd see 22+.

18 MPG & 306 Miles For The Trip (No Gas Light)

Made a concerted effort to fill the take as much as possible. Tank was just off of E, light just came on. The pumped auto-clicked off at 14.5 gallons, I was then able to slowly dribble fuel in all the way to 17.00 gal exactly. Tank was so full that a small pool was sitting at the top of the neck.
99' Limited - Completley Stock (135k miles)
Stock size tires at 35psi
70% freeway (+\- 60 mph) 30% in town stop and go
AC on 90% of the time
Fresh oil change and brand new Toyota air filter

I pulled into the gas station at 306 miles, guage was couple ticks above E with no gas light on.

Equates to exactly 18 MPG. Not the best mileage but it runs flawlessly.

Whats this M...P...G you speak of? LOL

Recently I drove from Ft Worth, Tx to Charlotte, NC and back. Disclaimer: my rig is supercharged and auto. I found that keeping the motor at 2600 rpm would usually get me 19- 20 mpg. That is all highway driving for the full tank of gas and would keep my speed between 75-77 mph.

My daily driving is a mix of city and country roads so I average 15-16 mpg.

The chassis has 340k, engine has 183k. On this engine in the parts truck I saw over 22mpg on long trips before.

Now that the engine is in the new (old) truck, my last three fill ups have been 18.51 to 19.01 MPG. Bigger tires on this new truck though.

On this same commute in the past in the parts truck, I would average 20 mpg between fill ups.

Wife's 5th Gen is finally breaking into the low 20's between fill ups at 5000 miles on the clock.

 

[fan of fanboys]

I keep fuel records for every fillup (I know I'm a geek).

In the summer I average about 18.5 sometime as high as 19 or 20 (highway only).

In the winter I average about 16.5 to 17 mpg because of government mandated winter blend fuels.

Isn't it great? The govt is saving the world from our vehicles by making them burn more gasoline...........

.

should def be using app fuelly then. free and will make your life easier

Your topping fuel off is filling your evap canister with fuel. Not good at all. Also gas tanks need room for expansion. Topping off like that allows no room and could cause an issue.
Also some gas pumps will actually push that gas back down the pump into the station tank if your tank is full.

I get 14.5 basically all city driving. Used to get about 18 before the lift, tires, and roof rack. Luckily it doesn't get driven very many miles during the week.

 

[duke808]

Got 20.8 going from LA down to SD the other week. Going around 68. Just bought this car so I went slow and calculated... was curious. Did a Yosemite trip about a month ago and was getting 19 hauling 75-80mph +1 human and some luggage up from LA to Yosemite. Not too bad!

 

[Scramble]

18.5 avg before lift & 33's - 16.5 mpg after... 2.7L 3RZ 5-speed - you have to stand on the skinny pedal.

 

[IdahoAngler]

3" lift on 255s (33.5"); roof rack with spare on top.

Around town I get about 15mpg; on the highway, I get about 18-19mpg on a good day.

 

[LeeMajors]

00 3.4/auto here with stock sized tires, no lift.

I average 20-22mpg depending on my hwy/city mix. Occasionally if I'm off and just in the city about the worst I'll do is 18-19mpg.

My gas gauge is also inaccurate and I get an empty light somewhere between 250-270 miles, which is usually about 12-13gal upon fill up.

 

[4Runnin2000]

I'm starting to realize that my mileage isn't very good. I only have 265/75s and a cheap rack. IdahoAngler has one size taller with the spare and still gets a little better mileage than me. I used to get about 250 to 260 to the tank city. Now it's about 180. Hmmmm..... I need to change something..

Load E BFG's, sliders...getting 12-14 city...with my check engine/rear C02 sensor on. I have a new one, just haven't put it in yet.

 

[sport05]

13.5 mpg in the city. 32" tires, roof rack, 3" lift

I call BS on several of these posts.

I didnt read all the post but what read seemed accurate.

I normally get about 18 mpg over all. I do mostly highway driving. I swapped out my factory fan clutch and picked up 1.9 MPG on my last trip. Lots of things come into play with MPG. How fast you drive, head wind on the highway and the biggest thing is how much alcohol they have in the fuel you pump into your tank. Ethanol free I have gotten as good at 21 mpg. High head winds and lots of alcohol I have gotten as bad as 15 MPG. Stock tire size, non lifted on my 01 3rd Gen. 258,000 miles and counting.

Filled up the other day and I calculated 13.9 mpg average. I am running 33s though and didn't account for the fact that in actuality I drove further than what the vehicle shows. But it's still under 15 I am sure. I definitely need new plugs and maybe even fuel filter

I've been averaging 18 mpg using 91 octane. With a mix of city and highway driving. The max speed 60mph.

 

[antexity]

Bought her in May and drove 6000 miles while averaging 18.6 mpg. avg. 80% Hwy with 33s and lift.

Here's a snap of my google sheet. (yes, I love data. Big Data analyst here..)

Will be charting it soon...
