MPG complaints/ possible fixes.

As a former second gen owner, the best way to get good mpg was to keep the rpms below 2k, and not to drive over 65.

I have noticed quite a few say they get crappy mpg while going 70-80 mph. It is a truck. What did you expect?

I get 18 mpg.
I also sit in traffic for an hour to get home. 13 miles away. My average speed is 18 mph.
But, as always,

YMMV.

 

65 to 70 is closed loop and will give you the best highway speed mpg. Anything over 80 is open loop and mpg goes down. I can't bare to do under 75 on the flyway.

 

"closed loop", "open loop" ????

 

@DukesTaco You zonies are nuts. you drive way to fast. especially in the rain coming down the I-17 from Prescott to the Valley.

 

I'd have to say 18mpg is probably the norm for stop and go traffic. Way better than what I get. My big heavy ass 3/4 ton diesel gets better mileage than my Tacoma does.

 

Closed loopopen loopif you can see the circle in the upper right hand corner that indicates if you are in closed or open loop driving. Open is bad for mpg closed loop is good for mpg.

 

I was raised in Miami Florida so I drive even faster in the rain. In the snow I do slow my warm ass down. I TuPac Avery day. "Doing 90 on the freeway".

yeah. People haul ass on the freeways in Fl. And I-4, what a shit show. Scary

 

Does anyone know how much additional MPG a tonneau cover adds?

 

In the past on both my 96 and 06 I saw and average of 1 to 1.5 mpg. I know many guys will argue it but that's my experience.

 

I would get that even if it was all down hill.

 

Hi DukesTaco.

I understand open and closed loop fueling, and I was hoping that you could tell us what apparatus/software you are using to produce the display I've copied, below.

Thanks................... Frank

 

It's a ultraguage that I got from Ramon's ultraguage group buy here on TW. That dam Ramon is like a crack dealer with his group buys.

 

A scangauge will also display a open or closed loop.

 

thats like any car though?
once you go past 70-75mph your MPG will go down.

I started driving slower for this very reason. I used to do 130-140km on the highway. Now basically do the speed limit of 100. maybe higher 115-120km. I normally get 600km on my jetta before the light comes on for fuel. Now that I am doing this keeping my speed down I'm at half tank and already did 560km. I also no longer accelerate hard. Honestly just not worth it. As much as I love speed and racing, not worth the extra money, risk of tickets, and most of all...after realizing regardless of what speed I do between 120-140 it saves me maybe 5 minute on my commute lol. Really do not care about the 5min.

And include mine is diesel and just driving differently has changed my fuel greatly (there's a lot done to the engine for performance so high MPG are non existent now)

Its just like how at certain speeds a lot of trucks have that cylinder deactivation shit. After 70-75mph it starts running on all 8 again.

 

Hey Guys, thanks for the word on Ultragauge and Scangauge............................ Frank
