    Keep in mind that the 2.7L engine used in 2005+ tacomas have a new engine with fancy variable valve timing and throttle by wire. I am able to get 26+ mpg without hypermilling, just regular driving.

    What really causes my truck to waste a lot of gas are:
    - cold morning starts
    - lots of short trips
    - hard acceleration/deceleration
    - stop and go traffic

    My truck is mainly used for work, carrying about 200-300 lbs of gear in back with tonneau cover. 34-35 psi in the tires. Use Arco fuel. My commute is mostly highway at 70 mph. I do my best to keep my speeds constant, especially when driving in the city. This is important. I am not sure if the valvetrain in the Tacoma does this, but in some engines with throttle by wire and valve timing, when engine is under cruise, the throttle is wide open and the amount of air is regulated completely by valve timing. This greatly reduces pumping losses and increases mpg.

    It isn't only "rolling down hill", sure that is a great time to shut the engine off, but frequently it is just rolling forward with traffic toward a red light. Any incline helps, but off ramps work, approaching a turn, pulling into parking lots, work, home, etc.

    I'll be gassing up later tonight, first 700+ tank in awhile, I'm loving the warm/hot weather. :D

    Best tank since 2008. :headbang:

    701.3 miles on 19.306 gallons for 36.3 MPG.

    180 miles driving to Denver and back 3 times really helped.

    Only $0.40 Safeway discount, so $3.229.

    Thanks, weird as it seems I think the Michelin Rain-x tires have taken over 10-15K to break-in, I've had them since late 2009 and the first 3 years they sucked for coasting, but now they finally seem to have better rolling resistance like they advertised when I bought them.

    Worthy,

    Will be needing new tires soon, probably this fall or early winter. The Firestone LE OEM's have been great. They have never needed rebalancing and have worn perfect. Only rotated 3 times at 15 to 18K intervals. I am considering the new Destination LE 2. Read in a Tire Rack review that they are supposed to have 15% less rolling resistance, although I can not find that info on Firestone's website. They are getting great reviews and are reasonably priced. During my 3.5 miles trip to and from work I am coasting in gear about 1/4 of the time, so I am looking for LRR tires. The Tire Rack does not list them as LRR. My Firestone store is horrible, arrogant and all they care about is upsells, with slow service. Thought about Michelin's but they are a lot higher, and previous Michelin purchases have been so-so experiences.

    Again congrats on the great tank.

    Well, I technically have three:
    -front mudflaps gone when I bought it
    -tonneau cover, which may or may not help
    -about a 50% grill block that lets the engine warm up fast, and moves more air over the truck rather than into the engine bay and down. I can run this even in summer because I don't have to cool an auto tranny and don't climb mountains or tow big trailers. Highest coolant temp I've seen thus far is 197F running the AC on a 90 degree day. Once it gets up to 100 degrees out I'll probably see water temps a little north of 200.

    In addition to the other benefits mentioned in other posts, the 2nd gen 4 cylinders can also use the benefits of 0w20 synthetic oil, and 09+ come with 75w85 in the differential(s).

    I agree, I'm comparing the Michelins to the Firestone OEM and the Michelins are just now getting close to the stock tires. I only got 46K out of the Firestones, not sure what they are rated for. Mine wore pretty evenly even at 45psi.

    The Michelins are 90K tires, there should be some LRR improvements before I need another set, it won't be these again.

    You know what, I think I might be brave enough to push this 4x4 to 500 miles this summer. I'll do it with a jerry can in the bed, just in case.

    This one was 26.5 mpg.

    That's awesome, but still a little close to push 500. Keep in mind that the 514 on 21.19, that was 24.3, but it was a matter of being broke the day before payday so I dropped a $20 in the tank and added the two together for the fuelly entry. The numbers are correct, just split between two purchases.

    500 miles at 25mpg is 20 gallons. That's cutting it way too close for my comfort, even with a calibrated scangauge.
    There's just no reason to run the tank that low. I think a more appropriate title for this thread would be "4 Bangin, Fuel Sippin, MPG Challenge!"

    True, true. I'd hate to suck air and hurt the pump. If you notice my fuelly I almost always fill around 12 gallons thanks to my last truck's 4.7 miles from light until dead episode. If I can't brave 15 gallons, how am I going to do 20?

    Yeah, I probably won't.

    I generally fill up on my way home from work the day after I break 250, so most tanks are in the 350 to 370 range.

    400 would be no problem, even at 22mpg that would only be 18 gallons, but my commute is 45 miles each way, and I prefer to buy gas here rather than near work because it's cheaper, so when I'm at 350, I don't want to chance 450.

    I'm comfortable at around 350 miles but not opposed to going up to around 400. When looking at my data, I can see two distinct bins reflective of my past two work commutes. At present, a week's worth of driving is around 350 and 15-16 gallons of fuel. I feel comfortable with a weekly fill-up around those figures. I've thought about the 500 mile tank, but I'm skeptical about being able to pull the numbers off without absolutely ideal conditions. And risking a 9/10 year old fuel pump on the venture makes it more unlikely. Getting down to less than a gallon in the tank had me pretty nervous. I'm thinking I'd be running it dry to reach the number (under the current configuration). Better to optimize than to maximize!

    Put in 21.02 gallons once. Just to prove it was a 21 gallon tank. Ultragauge monitored of course. Did not sputter once.

    Edit: It was only 20.99

    Now awaiting lecture.

    What the heck were you thinking, Dan!!:)

    Oh, OK then (just noticed your edit). Now that I see you had a reserve of a few teaspoons of fuel, there wasn't anything to be worried about.

    20.54 is my max, I usually don't go more than 50 miles past the light coming on but with a relatively short commute under 10 miles and several gas station choices along the way, I could push for 800. :eek: No I won't. :eek:

    Well I made the trek across the US. From Bend, Oregon to Nashville, Tenn. I reset my 2nd tripometer before leaving and it read 2394.2 miles when I pulled into my friends driveway in Nashville. I averaged 24.3 mpg over the entire trip. Mind you my truck was loaded as full as it could be in the cab and bed with all my stuff. Plus I have a canopy shell on it which weighs about 150-200 lbs. My best tank being 25.7mpg from Rock Springs Wy. to Denver Co., I also had about an hour of stop and go traffic on that tank. My "worst tank" was 23.4mpg from outside Denver to somewhere in Nebraska.

    I am thoroughly impressed with my mpg during this trip. I made sure all my fluids were correct, fresh synthetic blend oil change, rotated/balanced my tires, as well as proper tire pressure. No mods to my truck. I never used my AC once on the trip. I would roll down the passenger window a few inches, open the cab window and the windows to the canopy and that would create enough of a draft through the truck I never needed AC. I drove anywhere from 70-78 mph the entire way. Cruise control doesn't work very well on hills so I used my big toe mainly to keep the acceleration steady. Overall I am very impressed with my MPG for this trip. Was expecting 20mpg AT BEST being the truck was loaded down. I even got pulled over in Kansas City for my truck looking "suspicious"... haha!

    Bought my used 2011(bone stock 2.7, 4x4, auto), 12 weeks ago. Had the "opportunity" to do a ton of freeway driving and light hauling last week. I was hauling rental tables and chairs back and forth, had AC on at times and tend to drive in "3" rather than "D" in heavy city traffic. I was shocked this was the tank full that got me to 400 and my best mpg to date of 22.32. I am very optimistic I can get more out of it with some tricks, mods. and better driving habits.

    I know I might lose my man card here...but this made my day..and..I had to share it someone who might appreciate it!

    On a different topic. Got to see firsthand how "non robust" my stock 3 leaf springs are. Went to dealer yesterday for free oil change and mentioned it to the Advisor. He claims Technician visually checked it out and said nothing was awry. Also said it was too late in the day for full blown test drive and inspection, he would order that up on next free oil change.

    The good news is the Advisor did put it in writing, on the invoice, my complaint of a "harsh ride". Also I still have 18 months of warranty left on the truck. So hopefully I can build a case by the end of this year for the TSB 4 leaf replacement.
