Hey all,

Just wondering, what is everyone's average mpg on their car? I have about 72000 on mine, I don't always use premium and will use some octane boost, but what's normal and what mpg is a concerning number ?
Thanks,
Nick

princelybug · 01-01-2018, 10:39 PM

I average 20-21 mpg combined.

Thanks,

I'm looking at 17-18 but on 87 which the manual says is ok to use. When I put octane boost or cleaner, it's maybe one or two more .

I get 13-14 mpg combined (probably more city than highway).

All highway I get 27-29 mpg. The best I ever got was just a touch over 29 mpg.

FYI, I don't usually use the on-board mpg estimator. In my experience, on my E90, it is perhaps 0.5 mpg optimistic. When I get gas, I just divide the miles driven by gallons filled to estimate mpg.

3.0L single turbo, 6 speed automatic, xDrive, and I always fill with the highest octane availible (usually 92oct where I live).

33 MPG average over 70K miles of 90/10 driving, torque of a V8.

Who says diesels are evil?

My 335xi gets 18/19 city. I've never taken it on an extended highway trip preferring to let a rental take that abuse, but on shorter trips the computer has claimed 27-31.

YasF80_SLO · 01-02-2018, 08:05 AM

15 average, e30 fuel.

siphor1989 · 01-02-2018, 08:08 AM

13-14mpg almost all city driving. Doesn't help that it's now winter and my commutes are like a mile each way....

CTinline-six · 01-02-2018, 08:17 AM

21-22, up to 27 on the highway.

MPG is the least of my concerns expense-wise when owning a BMW though...

tcphoto · 01-02-2018, 08:25 AM

I get about 21 around town and 28 on the highway. Why would you use anything other than Premium?

I've seen some turbo diesels do great things that's awesome

Great numbers, thanks. I know it sounds silly, it's almost another 50 cents a gallon for premium, I'm being cheap I guess. Since the manual said it would be fine, I went along and did it. If it said I couldn't, I would definitely only fill premium.

Is e30 a European or international fuel grade ?
Thanks

With the turbo cars some people run a mix of ethanol and gasoline for more power. E30 would be 30% ethanol content in the fuel. Most gas stations you see (at least in my area) have E10 fuel and will say "contains 10% ethanol" on the side of the pump.

Nick

That's not ok. But ok. Minimum is 91 octane. Anything lower and the car has to retard the timing so it can run optimally, actually sub optimal to prevent damage. Run super and only super. Don't cheap out on gas. Also stick to top tier gas.

WatchWolf34 · 01-02-2018, 09:21 AM

I'm FBO - running 93 OTS Cobb tune and average 23 mpg with a mix of city and highway. About a 50/50 split.

Thanks I thought the manual said 87. Maybe this is why it went in limp mode

Weird I just checked and for 2006 it says minimum 91 2007 says 87. What year is your car? Also in the winter I would run higher octane fuel. The car just runs better.
