Let me know if this is completely normal cause I'm stumped. Am praying to god its normal.

New Index 12 injectors
cleaned intake valves
other stuffs

Getting around 10-11mpg at city driving (I average like 10mph). I live in an area where there is a stop sign about every block or red light at every block (pretend new york city short blocks) Highways I average around 24-28 mpg (pretty normal IMO). Can anyone let me know if that's normal. . Will send a Screenshot tmrw of my trip log. ON mhd stage 1+

Are you referring to City mpg, stop start traffic?

or combined (City/Highway) mpg?

Mine never dropped below 16 mpg since I replaced my injectors.

I'm referring to city driving. I live in a dense area with lots of red lights and stop signs but not traffic. 80% of driving is in city

Ok, i do a lot of city driving, including start stop, traffic etc

The worse mpg I've got now is 16mpg combined. Even when I rip it everywhere, it doesn't drop to 10mpg

here's a photo of my trip.

Probably normal for stop and go. I always used to get 23.8 average on 93 but I live a bit out from the city so very little stop and go.

'Officer we're in a recession here, that's why I was speeding!'

Ya at only 10mph avg that's probably normal, go faster and make sure brakes are good lol

I WISH. I step on the gas go 20mph and I see a fat redlight in front of me

[Hoody007]

FYI, my mixed is 22 mpg, if I drive more city miles it goes as low as 20.
I’ve seen highway economy as high as 28mpg @ 80mph.
City alone is around 18-19 mpg. I’m stock, though.

Coasting to stop helps a great deal! Makes brakes last longer too.

At that speed 10mph, your barely going to 2nd gear, looks normal to me.

need to get my front break pads done just remembered. very squishy brakes.

So basically you are at idle all day sitting at traffic lights. Yeah car is going to have crap for mileage. In general BMW seem to get best MPG at about 3500 rpm in top gear at sustained driving, stop and go is for hybrids..

3500rpm in top gear? So 100 MPH? Ya I don't think so. The aerodynamic losses will far exceed any "savings" from running the engine at optimal load.

Around 50-70mph gives the optimum fuel efficiency. Can't remember the exact figure. Definitely not at 100mph though lol.

Idk if its normal but dont feel too bad. I was averaging indicated 6mpg (lowest computer reads) and about 20 - 24 mpg purely highway over a 3 hour drive at around 60mph. Calculated average is about 14 mpg lol

[zero2sixtyZ]

Are you on a MHD Stage 1+ tune with TD04 19T turbos or a custom tune?

[E93Dude]

If you are driving an N54, the only way you are getting less than 20 mpg (let alone 10) in a stock vehicle, is if there is something terribly wrong with your car…or you drive like a complete asshole.

Getting 25 (or more) in stop/go traffic with manual transmission is not rocket science.

It's actually quite easy to get well below 20mpg, just drive through city traffic on a regular basis at very low speeds or gridlocked traffic and kiss your MPG goodbye lol.

Also ripping it at every opportunity you get will also tank your mpg.

I'm getting about 16mpg average, with New Plugs, Coils, Index 12 injectors and no issues other than whining turbos which are still boosting to about 20psi. Although I admit, I do rip it quite often as I prefer to be on boost than drive like a granny trying to maximise mpg.

Stock I remember my combined used to be around 18mpg. 30mpg is easy to achieve on dual carriageway/motorway/highway

Mine is about the same with mainly city driving and always in boost. On the highway, i will get close to 30mpg cruising but in the city it’s closer to 10mpg

First of all, ladies and gentlemen can we all just take a minute and bow our heads in silence for our brothers and sisters in Europe who are paying absolutely batshit prices for gas/petrol? Fueling up wasn't cheap before Putin lost his marbles, but a quick search and some maths indicates that at recent London prices, GBP 1.99/liter premium equates to about USD 9.19/gal. What a drag. What an absolute drag...

I'd be curious to see for comparison how much better your normal mileage would be (in what I am guessing is a lot of traffic) if you tried to drive more conservatively. Could you get into the mid 20's?

But to my original point, if you sit in stop go traffic and mash the gas pedal to hear that turbo whine all the time (aka "drive like an asshole") - yeah, your efficiency will plummet. I've never seen <20 despite having spent time in vehicular nightmares like NYC and the LA freeway, and currently get about 26/27 over a 40 mile daily commute in mixed traffic. I generally don't give my car a workout except on weekends blasting down nearly deserted country roads. That is when I get in touch with my inner asshole.

For anyone looking to get better mileage, my thoughts:

-- Drive normal, and avoid constant acceleration/deceleration (i.e. racing from stoplight to stoplight)
-- Get up to speed at a reasonable pace. Mashing on the pedal from a dead stop crushes MPG
-- Walnut blast. We all know about gunked up intake manifolds from the GDI. I blasted mine at about 95K for the first time, and the removal of all that crud visibly improved MPG. I went from maybe 29 on highway up to 33 if I was gentle.

Yes it's possible to get into the twenties if you driving Conservatively and are not stuck in traffic frequently. It's not about mashing the pedal off the lights, hardly see anyone do that here, On highway/motorway it's possible to get near 40 mpg, if you drive off boost like a granny but most guys tune N54's for performance not to eek out max fuel efficiency. I don't rip it from a stop light, but I do downshift often and put my foot down on dual carriageways /motorways etc to overtake slower traffic from the fast lane. Constantly stopping and going, particularly using lower gears drinks fuel regardless of how you drive. I've already had Walnut blasting done, including Index 12 injectors and pretty much all maintenance, save Rod bearings which I hope I don't have to do.

I've paid ~ £2.02 per litre on V Power the other day, and still rising. Paid ~£70+ to drive into work for 5 shifts. If it doesn't stop going up, driving is going to a be rare luxury.

Just watched a video on price of oil and the guy basically explained since 2008 price per barrel of oil has actually gone down, but other factors such as Ukraine war, dollars to pounds exchange rate including our "Great" government who don't think twice about screwing over the public, have been upping the fuel duty/tax. At one point this snake Rishi Sunak claimed the government would reduce fuel duty/tax by 5p per litre, never saw it, all I saw was consistent never ending rise in fuel costs at pumps.
