JB4 daily driving MPG

[Aarvix]

BMS states that mileage is unaffected by the JB4 when you drive easy and stay out of boost. I thought I'd put it to the test.

I photographed my trip MPG after every morning commute last week. My commute is ~43mi, and I stop at Buc'ees every morning for a breakfast taco, perfect time to snap a pic!

Every trip was done on Map2 in ECO mode, 93 octane.
This consists of 5mi stop-and-go traffic, 5mi high-speed tollway (go 90 or you're getting passed), and 30mi of medium traffic highway (avg 60-75).

As you can see, BMS is telling the truth; stay out of boost and the JB4 will not kill your mileage.
NOTE: I only tracked morning commutes because:
1) traffic is more consistent in the am, and
2) I cannot behave myself in the afternoon, and MPG suffers greatly.



26.4 MPG = 8.91 L/100 km
29.0 MPG = 8.11 L/100 km
28.7 MPG = 8.20 L/100 km
30.0 MPG = 7.84 L/100 km
28.3 MPG = 8.31 L/100 km

(EDIT: added communist unit conversions for the Aussies)

Those are good numbers communist or otherwise.

Wow - you'd better hope that Liberia has your back during the next phase of the revolution, comrade ...

 

[Aarvix]

My apologies to any Canadians/Europeans/Asians/Antarcticans who feel left out of the joke.

 

[Terry@BMS]

Thanks for the confirmation.

I never noticed any drop in mileage using JB4.
The car is faster only when you want it to be.

 

[Sasquach]

That's pretty decent numbers on the L/100KM, I rarely see less then 14L/100KM due to traffic but on a long drive i did hit 7.6L/100KM.

Just remember Communist Puns aren't good unless everyone gets it.... lol

I get 22.5 on e30 running map 5 daily.

What? What's ECO mode? Now you're just talking crazy.

No that was the joke part. No wonder no one got it. What is ECO mode anyway?

 

[asciidic]

I too tend to drive in eco mode in the mornings due to a heavier cop presence and me getting 2 speeding tickets during morning commutes so far this year.

Great job putting all this together! I can confirm that my MPG is also completely unaffected by daily driving Map 2 on 93 octane... Well, as long as I stay out of boost, but let's be real, who's really staying out of boost?

Jokes aside, even with relatively spirited driving, my fuel economy has been pretty good.

 

[HTmode]

What mpg do you get running sport mode on map 2? Since I never drive without it lol

 

[Pnbnationsbest]

You aren't driving in sport mode for economy so stop it.

 

[Aarvix]

Sport mode often involves spirited passing and speeds of questionable legality. 20-22 at best.

 

[Revvdmedia]

Sport mode MPG = Very bad.

Sport mode smiles per mile = Very good.

I just drove from Hendersonville NC to Gettysburg PA today (about 520 miles) with my 2018 2.0 on Premium fuel and on Eco mode and got a real time calculated 34-35 mpg. Also had to keep it in Eco mode since the state troopers in Virginia were everywhere!!! Just turned 6000 miles today.

I drove from SLC to Denver this week and got 34.5 mpg on map1 91 octane in eco with the cruise control just set between 65 & 80 depending on cops. 3.3T motor

Quite impressive. What was the actual calculated mpg after fill ups?
