Fuel tank size? - New 2009 2010 BMW Z4

morfinx · 12-06-2012, 05:39 PM

I can't seem to nail down whether it's 14.5 or 15.5 gallons (US). Both numbers seem to show up in Google search. Anyone knows?

While I am unsure of the official size, I can say I have never put more than 12.5 US gallons in my Z4. So either the reserve is much bigger than I think or the gauge is off. Maybe others can share their largest fill and typical fill numbers.

my largest fillup on fumes was jsut under 14 gallons. I was under the impression it was a 14 gal tank.

Hmm 14.5 sounds about right then. Supposedly reserve is 2.1 gallons.

Therein lies the discrepancy. Mine is on page 148 of the manual (both print version and PDF version):

Wait a second... I think I figured it out! Google says 55 Liters = 14.5 Gallons! That must mean there's a misprint in the manual!

I've filled close to 14.5 several times. car car says range _ _ _ and i drove for an additional 10-15 miles then fill up so 14.5 sounds about right

I checked the manuals. For 2009 and 2010 it says 15.5 gallons, but for 2011 and 2012, it says 14.5. But all 4 years say 55L, so I really think it's a misprint.
