Sdrive 35i f15 uses more fuel than xdrive 35i f16
Spark plugs same on both car. Air filters also same and replaced.
F15 uses 17litters on 100km qnd f16 15litters on 100km. I think high pressure fuel pump may be bad on f15. What pressure it must have? Both are stock. 125000km 140000km 0w40 in both car P.s. Sdrive f15 drives faster than xdrive f16. Ridiculous but fact. 20m rims on f16 315 35 rear. 275 40 r20 front 19 m rims on f15 255 50 r19 |

RE: Sdrive 35i f15 uses more fuel than xdrive 35i f16
You do realize fuel consumption is a bitch? Do both owners drive the same? Do they both use the same fuel? Tyre brand and pressure? Air dynamics is in play. What distances do they drive? Under what conditions(high traffic)? How heavy is the right foot of the F15 driver? What drive mode do they both drive in? First answer those questions before you fire the parts machine on it!
There is HPFP test in ista. |

First answer those questions before you fire the parts machine on it! I am the driver. I drive same places with both car. Same fuel. Sdrive no run flat Xdrive run flat Both 2.4bar front 2.6 bar rear. Same drive mode. (13-05-2023, 14:47 PM)bmchicago Wrote:I masured with drag race.(13-05-2023, 13:46 PM)bmwlover Wrote: Spark plugs same on both car. Air filters also same and replaced. Xdrive goes from place faster but at 70km/h sdrive catches it and than goes. |
