LOL hypermiling reports vs “conservative road trips”...

Here it is. 33.5 mpg for a over 20 mile trip. No out and back due to a route change so here is a screen shot of the wind at the time. 4 mph north wind. I was driving north so a slight head wind. Elevation went from 50’ to 160’. No drafting as video shows.

Enjoy.

So far for my first two tanks on my 316 mile old 2018 GTPP2 I got 14.8 MPG hand calculated when the computer said 16.3 MPG and 15.4 MPG when the computer said 16.8 MPG.

My commute is all streets and only was on the highway when I drove it home from the dealer and when coming home from 2 softball games. So probably 75% city 25% highway.

I will do a hand calculation when this tank runs down for comparison. The first 8 miles are not on the clock because I had to reset trip 1 after driving to the starting point since the fill up.

I will do one with the 8 miles calculated and one with out. It will not make much if any of a difference over the anticipated 230 ish miles on the this tank.

You can see lifetime on the car is 16.9 mpg according to the cpu so this tank hand calculated and the next should give me an idea of how off the car cpu is. I know a lot bigger sample would be needed to be more accurate but if both are with in a few tenths then good enough for me.

Almost as much fun as, "What's the best oil?"...

There's lots of mpg possibilities with resetting the trip display...short or long day trips, terrain, weather factors, good fuel..etc. All I have to offer this thread is my Trip #2 display which has about 2-3 months of occasional driving to work and town(3-4 days of the week)..to be honest I still find the mileage unbelievable lol..

I’m sorry, these cars aren’t capable of 34.7mpg on flat and level ground at 60 MPH or you bet your ass Ford would be advertising as such.

I can get 40mpg at times with cruise control on. Hell, the fuel shuts off completely down some of the hills in the mountains. Your mustang was only capable of going 34.7 mpg due to the elevation and conditions. At stead state on a level surface it’s just not happening.

So, what are your thoughts now that the video shows no drafting, no down hill and the wind was a slight N head wind?

Adjust for a +1.5 mpg error (which at this point is unknown but for arguments sake) we are at 32 mpg for a 22 mile trip. That fit into your knowledge base of these engines and transmission? Exact same speed as before, 60 mph. No touching of the brakes or gas.

I am guessing the higher temp, humidity, and head wind knocked the avg down from 34.7 to 33.5.

The video shows 33.5 but by the time I stopped the video and took the pic the trip reached 22 miles and the mpg went up to 33.6 but let's go with 33.5 since that is all the video shows.

:first:Good job KID!

LOL. Thank you. Thank you so much. I have never ever won anything in my life much less an internet trophy. The trophy you gave me will go in my internet trophy case. Well if I had a internet trophy case it would. Considering I've never ever never won an internet trophy before I just don't know what to do.



And for you seeing the winning going on it this thread, I bestow upon you an internet trophy.

I'd say your calibration is likely a good 3MPG off for whatever conditions you've been running in.

Why no out and back? Poor mpg on the way back is my guess. 20 miles is not enough to get a true reading - that's why the mpg is off. Drive at least 100 miles each way to get a better indicator.

Anyone who believes the mpg readings on the dash need to get a reality check. I check my average every time I fill up and most of the time the car is telling me I'm getting 2+ mpg higher than calculated. I'm sure some gauges are even more "optimistic". I have 2900 miles on my car now.

Had to take my mom to the doctor who you can hear talking in the video. Then I had to go to her house and the return trip took us another route which had heavier traffic so yes, it would have caused a difference outside the parameters of the test. You know, real life driving conditions not cruise set at 60 for 22 miles.

My overall for the car, 2600 miles now, is 16.9 mpg. So, I may be as low as 14.9 mpg overall. I have no doubt the cpu is optimistic thus the adjustment of 1.5 mpg down. I have to make the trip again tomorrow and it should be an out and back so 44 miles. I will have to fill up the car after the drive so I will be able to do a hand calculation and compare it to the cpu.

So tomorrow I will have a 44 mile out and back avg. I will also get the tank avg hand calculated so I will have some real numbers for yall.

Not going to film this time. Not worth the effort so feel free to say drafting, down hill both ways, or whatever.

If I take it easy I can get 26-28 with cruise at 67mph. 6 speed. My average for all over is always above 20mpg
