V8 mpg

[OzarkRunner]

My last two years' overall average is 16.0 (low of 13.4, high of 19.4, median of 15.9). I manually calculate each fill-up, and adjust for the slightly larger tires. My best tanks are highway miles, keeping a steady 65 mph. The worst tank was a Christmas day trip in the snow with a newborn - lots of idling and in-town driving in the Kansas City metro area.

I only go by the CPU - right after fill up my range says 275-285, my wife's V6 says 400 like yours.

Yikes.

I get an actual 400-440 miles to a tank in my V6 RWD, not even running it to the gas light most fill ups. Computer is way optimistic, it usually says 460-480 miles right after a fill up on range. But that works out, since it's roughly 8-10% optimistic on MPG as well (usually reads 23-26 mpg, actual is about 21-24 mpg - mostly depended on AC usage and cold starts which really suck up gas in this truck).

One of the keys of good gas mileage is not being afraid to toss 'er into some corners to keep up the momentum. :lookout:

I'm probably about the only person here who wishes for more front negative camber on their 4Runner to even out the wear. :nerd:

04 V8 AWD. When it had stock tires I got about 18-19mpg on highway. Put on some 285/70/17 Toyo AT II's and it dropped to about 15mpg highway. Around town I'm afraid to look.

2006 V8 and I get 14 mpg. All city/off road driving, 3 inch lift, 33 inch tires. Stock I got 15 city/20ish highway. You may see a slight difference between the V6 and the V8 but in my opinion the 4.7 V8 is an amazing engine. The V8's are extremely smooth getting up to speed and shifting.

I was dead set on buying a V6 4th gen (just because I could switch between 2wd and 4wd.) but once I drove the V8 I changed my mind. I gave up a few MPG's and a selector switch for a more pleasurable driving experience.

I miss the days I used to get 17-20mpg, I now get 11mpg on a good day because of my 33in mud tires and 18in wheels! :brick:

Does anyone else notice that these get really bad mileage when the engine is cold, or is it just me? If I drive to work (I usually bike unless the weather is bad) my engine doesn't fully warm up by the time I get there. It's only 2 miles each way, and today it was probably 50 degrees in the morning so not unreasonably cold. But it idles at 1,500 RPM while I sit at the first few stoplights, and I can watch the MPG gauge tick down alarmingly fast.

I'm afraid it will be even worse this winter. If it idles any faster I won't even have to press the gas. Talk about unintended acceleration!

Its because the 2UZ-FE is a Cast Iron block, takes a while to heat up fully; but it retains its heat far better also. Which means that the engine block is going to stay cooler longer which does affect the combustion process some, even taking into consideration coolant and such. I get pretty bad mileage because work is barely 1 mile away from my house and I mostly don't drive more than about 20 miles a week or so; so its a lot of "cold" driving.

This exactly! Coming from the 3.4 I definitely notice a difference, both in power and mpg. I'm probably getting 2mpg difference since I do mainly city driving with little hwy use. I'm averaging 16 mpg with the 4.7, but for how smooth the engine gets up and shifts it well worth the minimal difference. Plus I didn't wanna have any of the regrets of wanting more power.

17.7 MPG here with a mix of city/hwy driving. All stock on Michelin ATX and running the cheapest 87 octane I can find. My wife has started to drive it once a week for a 60 mile round trip and she is not as easy on the pedal as I am.

Check my stats at Fuelly.com. I updated via there app while at the pump.

Yep, it's an emissions strategy to get the cats to light off quicker. Basically as soon as the cats are starting to begin to warm up, the engine goes in a really rich mixture to fully light them off.
