Petrol/Gas B58 petrol fuel economy

[pmatusov]

Yeah baby…

Have you ever verified that number by what you pay for at the pump?

Have you ever verified that number by what you pay for at the pump?

I enter $/gal, gallons purchased, and mileage every time I fuel up. I don’t really concern myself with the $ just the MPG.

Nice. It’s inching higher. Are you driving normal or “hyper-mileing”? What tires are you running?

Just normal driving with no economy stress, press the fun pedal now and then, and stock 17” alloys with Bridgestones.

I love this thing!

I have a theory on the fuel consumption discrepancy between the IG computer, and what we see at the pump. Now my IG measures in L/100km, and it max’s out at 30L/100km (7.8 US mpg), no matter what my foot does. So when I’m using more than 30/100km (on that mad overtaking manoeuvre) does it still calculate the elevated consumption at 30L/100km?
I went on a 700km (435 mi) trip recently, not much heavy foot involved. The IG measured it at 13.2 L/100 (17.8 mpg), the fuel bowser measured it 13.5 L/100 (17.4 mpg). This is a 2% difference, however around town it is a 7% difference.

I always find it impressive how much is discussed about fuel consumption. If I drive 10,000 km a year and have a big car like an SUV, it doesn't really matter whether I need 10 or 14 liters. That's just 50 EUR a month. With a car worth 90 k, that's not really worth mentioning, is it?

My x 5 45e has needed 11.9 liters for the four years I've been driving it. I always ask myself why the damn thing has a battery? Oh yes, for auxiliary heating and cooling, of course.

It matters when you're out there for days without any fuel around.
Speaking of monthly difference - my old Range Rover manages about 11 mpg, making the Grenadier a fuel-saver at 14 mpg. The difference in fuel costs calculated using 15k miles/year and our cheap $5/gallon gas is $122 a month.
You can think of it as a new set of 255/85R17 Mickey Thompsons for the Grenadier, every year.

I feel for non diesel owners. B57 I have averaged 11.4L / 100kms taken at 15000km. Based on actual fill ups. However if the OD is out by 4%, it would push that to 11.7 or 11.8 per 100 in real figures... still good for 2.7 raw tonnes.

 

[pmatusov]

Update at 9k mile mark:

(Total miles driven)/(total pump gallons) = 14.0092 U.S. statute miles per gallon, or 16.7936 liters/100km for metric people

Upward trend…

 

[Tom109]

Nothing special, same roads, all local, and same fuel/station/pump as my last three tanks.

 

[MurphyMurph]

First fill up after my initial fill up and I got 15.3 mpg. Mixture of around town, traffic and some highway miles. For reference, the in-vehicle computer read a very optimistic 17.8 mpg when I filled up, so about 16% over the actual number.

Got this yesterday, city driving:

Been running a chipyourcar.com device plugged into OBD2 port for a few months now.

 

[MurphyMurph]

This was probably 60-70% highway speeds 60-65mph.

Mine displayed the average at 22mpg, but calculated out to 18.1mpg actual. This seems to be the over-reporting consensus.

Chip Your Car doesn’t have Ineos on the drop-down. I assume you used BMW? Which model? What is the downside?

Chip Your Car doesn’t have Ineos on the drop-down. I assume you used BMW? Which model? What is the downside?

I picked the following...
BMW Performance Chips

• YEAR:
  2024
• MAKE:
  BMW
• MODEL:
  X4
• CYLINDER:
  6-Cylinder Twin Turbo
• GRADE:
  PREMIUM (up to 60hp 5mpg gain)

So far, no noticeable downside.
