Anyone get 20 mpg with 4.0L V6 ?

I strongly suggest you consider investing in a ScanGaugeII, it will improve your mileage simply by showing you how your right foot dramatically reduces same, and little mods that you can make to the way you drive to improve things significantly. Also, read the article on hypermiling if you have not already done so, linky found in the last post of the mileage thread.

 

I have a 2006 4x4 DC LB and I get 17-18 mpg highway, 15-16 mpg city.

 

It can definitely be done. You just have to drive responsibly and stick to the speed limits. It's good up to about 70 mph. Once you get too much faster than that and your mileage will suffer. It will also eat it up if you launch the green light like you're in a drag race. LOL. I consistently get 400-425 miles per tank in my Double Cab Prerunner with stock everything. I currently drive 55 miles each way to work and back. Only about half of that is interstate. Good Luck!

 

Over 20 is pretty easy in the summer with my Access cab V6 4x4. I was getting 22 up until the cold weather. Now it's 18-19. Last tank with all highway was 19.5. I usually hold to about 65. Can't wait until it gets warmer.

 

Winter gas contains less than 2% fewer BTUs than summer blends, so while there will be a mileage difference based on the fuel composition, it won't be too significant at these mileages. One mpg at most. The real mileage killer in winter-time is a combination of cold engine and a short trip. If you do a lot of highway travel, commute 10+ miles, that sort of thing, your mileage will only drop a little, but if you do lots of short trips it'll suck. Your vehicle burns a lot of gas during the 'warm-up' period, and short trips means it does that each and every time to greater or lesser extent, depending on how much it has cooled between trips. Cooling is quite rapid.

With the ScanGauge you can see what is going on. Also, speeds over 65 just absolutely clobber mileage. Cruising around 60 or less (if you can safely do so) will make a big difference. I'd always heard all this stuff, it was the reason we were stuck with the much hated "Double Nickel" for more than a decade back in the 70s-80s (which many of you probably don't even remember), to save gas, but I never really believed it until I could actually see the evidence in front of my eyes on a real-time, continuous basis.

 

I can get 20-21 if i am doing all highway, but if you do 50/50 mix then you are looking at 18ish. And that goes down in the cold months, i'm getting on average 17.5 mpg everytime i fill up now due to the winter gas

 

I have an 07 tacoma 4.0 v6 double cab, auto, long bed, prerunner.

I commute 45 miles(one way) every day. 90 percent of it is freeway driving going about 75 mph. I routinely get between 20 and 22 mpg.

I recently took a trip from LA to San Jose and I was pushing the taco on the long stretches of I-5, going about 90 mph the whole way. I got around 16 to 17 the whole trip.

Anyway, I'm happy with the 20 to 22 for everyday driving. It think that is pretty good for as big as our trucks are. My dad has an 2001 taco, 4 cylinder, 5 speed and he get around 15 or so all the time. He's amazing at how my truck gets better gas mileage than his 4 cylinder.

 

In my 05 DC Pre-Runner I would get 18-19 mpg combined city/highway. In my current truck (X-Runner) I am getting 15-16 mpg same commute to work.

 

Hey, leave him alone... he's dating my grandmother...

 

I get 20-22mpg routinely on the highway. That is with cruise set at 70mph. On a couple of longer trips I got up to 23mpg for almost a full tank with the cruise on. With the colder weather I am down to around 18-19mpg.

Even when I was running down to Atlanta one trip with my cruise set over 80mph I still got 20mpg...

I am very happy with that mileage out of a pickup truck! My RX8 was lucky to get 18mpg with my cruise set to 65. My wifes Highlander V6 which I think should be a lot more aerodynamic than my truck is getting a reliable 22-24mpg, so not that much better.

 

14-15 all stock, with 1½ mile one way to job, all days (probably that is why I'm getting poor mileage), but on the end I do save more than the 45mile one way job trip. Other than the air filter mod and right foot therapy, what else is recommended to save fuel? I usually go with the mid grade fuel several times and then high grade at least once a month. Weekends is when I use it the most, going all places and across (México -border-).

 

Other than the mods you mention, I was looking at my owners manual and it recommends 87 octane fuel. That's "regular" around here. I've been in some places where 85.5 is "regular" but in most locales it is 87. Anything higher octane than 87 is a waste of money. Not only that, but your mileage will suffer slightly because the higher octane gas simply has more additives in it, meaning less gas and more gook that keeps the motor from knockin'. The idea that high octane gas is somehow better or helps your engine is simply a myth, but I'm sure one that the oil companies are only too happy to perpetuate.

Another thing is tire pressure. The manual gives those for the various tire sizes available on the different Taco models. I'd recommend going a little higher. I keep 35/35 in mine, although the manual recommends 29/29. It makes a difference. The only time you might need it lower is in an off-road application.

Weight is another problem. If you routinely haul several hundred pounds of traction-sand in the back of your truck, your mileage will suffer. I use it in the winter, a good handling/safety thing, but get it out of there when the roads clear up.

Sorry if I seem like a bit of a mileage Nazi. It's just something I find interesting, and especially now as gas climbs inexorably toward $4.....crude oil hit $107 a barrel in New York today, an all-time record, even adjusted for inflation, with no end in sight.

 

Thanks, I will take in consideration these remarks mentioned and apply them to my daily use. We still at $3.07 regular (85) and $3.17 mid (87) and $3.27 (92) high, we are "safe" by now, and uncommonly no to many months ago people from across (México) used to come and fill out their tanks with "better" gas at a better price than theirs, but now it is all turned around, "PREMIUM GASOLINE" (92) is cheaper in México than in the US. I have heard rumors of $4.00 USD by early summer, probably before that. Where is my Corolla?

 

That's absurd.

 

Feel free to buy all the high-octane premium gas you like, Exxon-Mobile will love you for it.

 

My manual says "91 for optimal performance" or something to that effect. Apparently the new models don't, so they must have changed something with the 07+ models.

I've run 89 for a month solid. I DID get better mpg because the cost/mile worked out to be the same. So I was paying more for gas, but getting just enough better mpg to balance it out. So now I just run 87 and save myself some change at the pump.

 

Mobile is a city in Alabama.

Mobil is the oil company.

Second point, I will not debate the mileage differences between premium and or regular, however, I will state facts. These engines make more power on premium than they do on regular. Roughly 9 horse and 11 lb-ft if memory serves. I have never done a mileage test on regular, hell I tried two tanks of mid-grade and was so agravated with the loss of power I felt (ie having to down shift to 5th on inclines that I could comfortably hold in 6th on premium) that I immediately went back to premium, and hell my Tacoma is not my daily driver, and it's primary function is as a tow vehicle for our travel trailer, so the power to cost difference is worth it to me, and besides, I am getting 20 mpg summer highway mileage with a 6 speed and 4wd, and have to most power the truck can make in stock form, I am good with that.

They did not technically change anything other than the wording. The wording was changed to reflect the change that the epa was making in having manufacturers base their power, torque and mileage ratings on real-world conditions. And fact is Toyota was generating their numbers on 91/92 octane and the masses were using 87, so in 07 they changed the stickers and the manual to reflect 87 octane.

 

Yeah um, wrong. It says "recommended" for a reason: The computer retards the timing to prevent the knocking and pinging you mention which, in turn, gives you less hp. Personally, I want all of the 236 horses I paid for so, for the extra $3.20 per fill up (based on the 16 gals I put in every week), I'll stick with premium. Hey, I can afford it. I'm more concerned about rising food prices caused by all the ethanol loving tree huggers.
