2014 Gas Mileage

...My post was not to tell someone that higher octane gives better gas mileage...I have no reason to assume that the higher refined fuel that cost more will yield a higher MPG on my 4runner than the less refined fuel ... I'm not trying to advocate to use higher octane fuel.

Holy Hell man go back and read your post! You even broke it down by octane!

What I took from your post is this:
"This guy makes some decent decisions being a 4Runner owner and all and hmmm, he is computer literate but man, don't trust his data because he is posting up complete fiction on the reasoning behind his mpg figures!"

That's what I took from your original post lol.
 
You 2014 guys using the OBC for mpg calculations need to be resetting the mpg display upon fillups from time-to-time.
 
I get 18.8 after 16,000 miles. I have 265 Duratracs on, Skid plate, Sliders, and Gobi Roof Rack. I drive 80 miles a work a day which is mostly straight, level highway in Colorado. The gas around me has 10% ethanol in it also.

If you're going to list your MPG, at least list the mods as well since that changes everything. I plan on getting a lift when I get back from Italy and will check again. I am hoping the lift doesn't do as much damage to the MPGs as my tires did.
 
This has probably asked/answered in the 2014 4runner thread but the epa ratings for 2010-2013 were 17city 19combined 22hwy but the 2014 is 17city 18combined 21hwy. Is this due to stricter epa testing or did something in the 2014 change to drop the mpg?
 
I'm averaging about 17.8mpg for city and highways (80mph), I get about 22-23mpg.

This is according to the onboard computer though.

What is your input/opinion on the fuel additives that can be found at places like advanced auto parts and autozone, or shell stations? I used to cycle between different additives in my Evolution X (inline-4 turbo) with high octane. The computer always gave me better fuel readings, and I would experience better MPG on longer drives, driving conservatively. But I always felt like there was a "drop" when the fuel level (physical) got to a certain point. I don't use additive in my 4Runner as often. Maybe every 5 or so fill ups. But that's because we mainly fill up at Sams club or on base, and I don't know the quality or source of the gas, so I use it mainly to keep the fuel system clean and from getting clogged or accumulating buildup.

After reading your post, I'm curious to know what you have to say about them.

The ones I mainly use are,

1. Marvel Mystery Oil
2. Lucas Fuel treatment
3. STP Gas Treatment

i'm averaging 18.4 and drive my TE fairly hard coming from a 370z. i thought it would be better if i could lay off the gas until i saw this. glad its where its at now.

Well the 2014 has more smog stuff on it, at least in CA (Some of it takes up the spot most people use for a second battery, the rest covers access to half the spark plugs and makes the others very hard to get too arg!).

So that may have done it or it may have just been retested due to the changes and got a different result due to random variations in weather, vehicle weight, testing equip etc...

Watch those 4 letter words . . . LOL. :eek::biggrin2: j/k

Agreed 100%

Toyota's seem to have one of the less accurate Avg MPG displays compared to others. People in the know say they don't sample the fuel usage quite as often as some other makers which adds a little bit more error in the average MPG value displayed. ODB scanners show the same info which confirms it's the design. We're talking small values here. This has been discussed ad nauseum on Prius and other hybrid forums for over 10 years.

I always hand compute MPG and record and compare to the vehicle displayed Avg MPG. Mine averages about +/- 5% different than hand computed but I've seen it as far off as 14%. All my Toyota's have been like this. It's not big deal if you know about it.

So those of you relying on the MPG display alone, are not seeing reality.

I won't EVEN get into the whole issue of over size tires with larger circumference, actual distance traveled, etc., etc.

It's a TRUCK. With skill, you can beat the EPA numbers a bit but not significantly. It's not a Prius.

I have a similar setup to you - 265 Duratracs, sliders, Gobi - and I barely average 16. I drive like shit, however.

I guess you missed the last sentence in my last post...:ranger:

I can get back into hi-jacking this thread and get into a pissing match, but what for? There are already too many on the forum, catch my drift?

Like stated earlier, what would I have to gain if I lie about the numbers I have? I don't have a reputation or big ego to prove anyone wrong here. :focus:
 
"pissing match"

Doesn't have to be. Watch my post close this thread. Engineer1 is right and showed it with facts. You have anecdotal evidence? I also have anecdotal experiences. Fstop from the hummer forums, who quite well know for Moab and his photography, discussed things there. Other things to consider, condition of pcv blow thru, carbon buildup, quality of sensors and ecu programming, and etc. fstop mentioned how gm could regard and advance timing. Couldn't get a mopar answer so I did the reboot by disconnecting the battery. Some jeepers in Texas use to alternate between rug and premium in hot summer months. These guys were off roaders. Again, engineer1 has given you the facts. Use the lowest octane gas and the highest cetane that the motor was designed for and works. Who knows the rug may have been the dumping ground for crap like in Houston in the late 80's or nineties?

A way to get the anecdotal experience across without starting a pissing contest could have been like- please help me is my 87 octane at my gas station bad. I tried premium and the Toyota readout shows better mileage. What's going on?

That would have been a better approach. Numbers always seem like BS when stated, but the math to calculate MPG are elementary.

So the question is this,
If I am traveling the same distance in a similar pattern of acceleration and speed during several trips, how come my numbers changed? I'm not one to seek a placebo effect.

I do have one question, I found this wiki: Toyota GR engine - Wikipedia, the free encyclopedia

Are the statements on octane true? I understand that the engine will retard timing if it notices pinging at the loss of power on higher performing engines, but does this statement hold true for our engines? If so, wouldn't the loss of power also have a possible effect on MPG? I'm really just asking without sarcasm, but to become well informed here. Not looking to dump this thread anymore as we have already hi-jacked the OP's original question.:dammit:

The 4x4 and 4x2 have a 1mpg hwy delta. Perhaps you are viewing mpg for the 2010-13 4x2 compared to the 2014 4x4? I know Edmunds has it listed kinda misleading.

Methinks Toyota is doing everything it can to increase the mpg for CAFE, not dropping it.

At least [MENTION=88820]The Waco Kid[/MENTION] got it. Guess I need to make my sarcasm more sarcastic.

Maybe [MENTION=48772]Jesse1983[/MENTION] can change the wording under your username from "Senior Member" to "Pure Unadulterated A$$hole Member".

That should clear these little mishaps up.
