How do you guys drive your 05?

I'm trying to figure out if maybe my poor fuel economy (14mpg) on my 05 6-speed DC is because of my driving style or something inherent in the truck. I've got almost 1700 miles on it. Here's how I drive, in the city I usually run it up to 2700-3k and shift, when I get to my cruising gear (if I ever get to it) I cruise at 2200-2500, pretty much smack in the middle of the power band. On the highway I cruise in 6th always, usually between 1900-2700+ depending on speed (usually 57~75+).

It's very similar to the way I drove my 95. I followed the same pattern, my shift points would be different because the engines are totally different. If anything I drive this new one a little easier even than my older one, mostly because it's new and I'm still breaking it in. Thing is, I had no problem getting 280+ miles on my 95, and over 300+ on the highway, and that was with 31's, 1.5" lift, and a slightly smaller tank.

So how do you guys drive your 05? Am I driving too hard? Do you drive like me? What do you think?

Well, My '05 access cab TRD sport is an automatic, and I figure those PHD havin' engineers have got it programed to do it the way they think is right.

So, here's what my automatic does when I'm trying to be nice and get some gas mileage:

I push the gas pedal down just enough to make the truck roll out of the stop, and leave it there untill I get up to cruising speed. I'm talking maybe 1/8" or so.

The truck revs up to 1,200 or maybe 1,500 RPMs, and shifts up to third right away.

It might take a whole three or four seconds to get to third gear.

After second gear, it hangs on to third fourth and fifth a little longer, but it still shifts before it gets to 2,00 RPMs.

Driving like this, I roll along at "Soccer Mom" speeds, and get 18 or 19 MPG in city traffic (That's Houston city traffic, and as bad as it gets).

My best ever was 25.7 MPG, Running 55-65 mph, drafting in a convoy of trucks, down hill with the wind to my back for 200+ miles with only one stop.

I can easily drag my mileage down to the numbers you mentioned, but doing so has me first out of the stoplight, and passing everything in sight.

I do that sometimes, but my driver's liscence and insurance is in danger the whole time.

On my 05 4Runner with the 4.0 v6 auto, my wife who drives like a bat out of hell can still manage to get 19~20 mpg in the city 23 on the highway. When I drive the beast, granny style, I am getting 26mpg driving 75 mph on the highway with no draft. Although we didn't get this good of mileage for a while after we bought it. It has 20k on it now and the mileage didn't get that great until around 5k. Might not be the same with everyone else and of course I am comparing a 4Runner to a Tacoma. But I am sure that the 4Runner is a bit heavier as well. I would think to give it some time and see, if it doesn't get better use the warranty to your advantage.

I average 18 with my 6spd access cab. The best I ever got was an even 20 once and the worst I ever got was 16.5 and that was driving it pretty hard. My best mileage comes when i drive between 45 and 60 miles an hour in sixth gear. Anything above that and I start losing. I am actually dissapointed with the highway mileage which you think would be better than around town but its not. I get my worst mileage on the high=way. I can run between 300 and 330 miles per tank. That is driving with the fuel light on for ten to twenty miles.

You're not going to get great mileage right away. My 05 has about 8k on it and I get between 19-21mpg constant. I drive mostly highway but when I acclerate, the truck never gets over 2200rpms. It gets just a bit over 2k rpm and then it shifts, unless i need to acclerate hard then it jumps up to about 3k. I dont drive it much harder than that and I get pretty good mpg. I would say that you are running up the rpms too high. Maybe drive someone's 05 that has an auto and feel the truck and watch the rpms. These days the auto's get better mpg than the manuals so I would try to follow the shiftpoints on an auto? My

I think that the manuals tach higher at highway speed than the auto.

Me too.

Hmm, that's interesting, maybe I am running the RPM's a little high. I've decided to experiment with this tank, I'm shifting at much lower RPM's and crusing at 2k and no higher. We'll see how it works. Thanks for all the great info.

I usually drive it like I stole it. haha but then again I average 16 miles to the gallon.
When I do drive it easy I get about 18 miles to the gallon.

The best I have done was 22 or 23 miles to the gallon and that was the same trip as Frank.

Does any one know how many gallons you have left when the light comes on?
I have driven 50 miles after the light turned on. Only because I was on a highway and there was literally nothing for 50 miles. I was sweating, I thought I was going to have to walk. The light did come on two days ago and when I filled it up it only took 16 gallons which would imply 5 gallons of fuel for the light to come on but that does not seam right.

My light always turns on with about 1/8 of a tank left and then over the next 5-10 miles or so the dial moves to vertical. At that point I usually fill up cause it looks pretty empty, I'm always in the 16.5-17.5 gal range. I think it's probly a 19 gal maybe a 20 gal tank, but I'd be really surprised if it was 21.

That's what I would suggest.
Cruising above 2000 seems pretty high. I have an auto but this is what I've observed. In the city cruising going say a steady 30-40 mph my RPM's sit at around 1100-1300. On the highway cruising at 60mph my RPM's sit at 1850-1900. Assuming I'm driving normal and not hammering it, my shifts occur between 1900-2200. My average for MPG is about 20, and I'm lifted and running 32" tires also which I have factored for in case you're wondering. If you follow the shift range and the RPM cruising speeds of the auto you may have a better idea of where the best fuel economy is.

Good Luck

The tank is 17.6 gal. Assuming I have a full tank I routinely go about 340-350 miles. Usually when I fill up, I'm like you, usually in that 16.5 gal range, meaning there is a gallon not burned. I take 340-350 miles divide it by 16.5 and that works out to about 20-21mpg.

If you put 16 in when right around the time the light came on that would mean you had about 1.6 gallons left in reserve. 17.6 -16= 1.6

Im pretty sure the 05 gas tank is 22 gallons. I think i remember seeing that in the manual.

ya i was gonna call bullshit on that one as soon as my light went off today, i pulled into a gas station and filled up all the way and toping off by adding 18.25 gallons (exactly $50). So i dunno, someone do the math.

i believe it is a 21 gallon tank. i am only getting about 285 miles per tank if i push it. something like 14 mpg. i usually end up putting 19-20 gallons in it when i fill it up. i drive 99% on the streets (hardly ever get it on the freeway). mine only has 5000 miles on it so maybe it will break in and get better mileage (i hope). i take it pretty easy on the gas pedal. love the truck - hate the mileage. my wife's yukon xl gets better mileage!

Well to summarize, the tank is 21.1 US gallons, or 17.6 imperial gallons, or 80 liters, all are the same. Now on a full tank I can go 340-350 miles, or 550-560 KM both are the same. When I fill my tank I usually put in 16.5-17.5 US gallons, or 62-66 liters. Do the math and I usually get between 19-21 mpg. I keep pretty good records, and I never was as low as 14 mpg. When I first got my truck I was around 16-17 mpg, and it slowly but surely creeped it's way up to were it is now. I have 14236 KM which is 8846 miles, and I've had my truck for a year,.... as of today actually.

Now white_eskimo said he filled up as soon as his light came on and he put 18.25 gallons in. I guess the light comes on with around 2.5-3 gallons or 10-11 liters left in the tank. So the light comes on when the level drops to 1/8th of fuel remaining. That's sounds about right to me. Assuming I'm getting say 18.5 mpg (we'll play it safe), once the light comes on I should be able to drive an additional 50-55 miles or 80-90 KM.

What do you guys think?
