RTD = Real Time Data- the data stream from the sensors shown in real time. I was asking if you had compared it to someone with a similar vehicle. But, maybe it's irrelevant and your Yukon actually is running as it should. I know you said you idle a lot, but I didn't understand the full extent of your "idling a lot". You a PI?

No, I'm a husband and father! Wait in line to pick up the children from school, wait outside 2 or three nights a week while they play volleyball at a gym with limited seating, sit in the parking lot forever while my wife runs inside the store for one thing that turns into forty and 5 songs later.

Here's another topic for you, the fuel gauge.

On all of my previous GM vehicles going back to the 1970s, the fuel gauges stayed on full for a while before swinging to just about or under half and then running down consistently towards empty.

This truck comes off of full very fast and hangs for some time at 1/4 tank or less. One night with the Tech2 hooked up I drove about 50 miles and the tank said I had 10% of fuel remaining that whole time, until I went up a bridge and it dropped to 2% then back to 10% on the way to level ground.

On that last fill up, the tank was showing a 1/4, it took on just under 15 and the Tech2 read 98% full. I forgot what the Tech2 read before fueling percentage wise. Ahh! Just more useless information!

04 with 154448 on it. Current tank is getting 16.6 mpg after 288 miles. Have seen anything from 14's to 19's average depending on my driving.
Interesting side notes on things I have never reset:
Avg econ: 16.4 mpg (life of vehicle)
Hours: 5478.9 (life of vehicle)
Avg speed: 28 mph (life of vehicle)
Don't have a gallons used as I reset that with my "personal" trip at every fill up and I don't use the "business" trip ever.

My fuel gauge when I fill it likes to hang out at 3/4 to 7/8, and slowly creep up to full after I drive a few miles, then seems to be accurate all the way down to empty. I blame sulfur.

Noticed this too when driving to the lake, but also how do you guys get 18-20 i have all the intake exhaust and i get about 10.8.. And im not too harsh on it when i got the diff rebuilt i had to drive carefully for a certain time and it wasnt much of a difference maybe went to 11.5.

10.7 mpg with about an hour of idling. Some for the kids, lots fooling with the Tech2.

I've always known fuel gauges to seem to drop more slowly from full to around half-full, then drop much faster from around half-full to empty. I've noticed this with various brands of vehicles and assumed it was because of topping off the tank. Never gave it much thought beyond "I should get about 100 miles out of each 1/4 of tank".

At this point, I would be interested to see the graph of everyone's tachs. Also what rear end you have. It seems some guys run 10-14, and others 14-19....model years are all over the board... Weird.

I think it should be required to have basic info in our sig. Maybe have extra required spaces to fill out when you first register to the forum: Your screen name, year/make/model (and trim level?), engine and trans. Maybe even have gear ratios, color, etc. as optional spaces.

Made it to 11 mpg today. The weather is finally changing, it was so nice we shut the motor off and left the windows open and stargazed and played with the Tech2 until the mosquitoes found me.

I never reset my engine hrs and fuel used since new...

And i was at about 1/2 tank and 12.4 avg mpg

swathdiver · Oct 21, 2017

Last fill up it was 8012.1 gallons used and 1449.7 engine hours. The odometer was right around 120,500 then too. That gives a liftetime fuel economy average of 15.04 mpg and it's average speed then over 83 mph! Well obviously that shouldn't be right, right? I reckon then that someone reset the engine hours at some point. I was hoping it was original, darn. Well, maybe it is a new motor or the AFM was repaired or something. That remind me, will all GM dealers have my truck's service records if it was serviced at another GM dealership, even under a different owner in another state?
