Fuel consumption on a 320i 2001 model

[Barkie]

My wife's 320i will run on the open road at 7.7l/100km but in town it is on 14-15l/100km. I am use to my 330d that is good even in town but is'nt 14 a bit heavy for a 320. The car also seems a bit lazy below 4000 RPM. Was serviced in April this year.

Seems heavy. The gopher, (318 A/T) i get open and traffic 9.5 /10. Depends on How happy i get with my right foor. Could be how she drives in traffic???

My wife have 2 positions on the accelerator. None and all the way to the floor.

My 2003 model liked to ref. Wanted to ref. I got around 8.5 km/litre in town. If you wanted that car to move, you needed to get it over 4000 rpm.

 

[Barkie]

What seems strange is, even when you drive light feet, the consumption needle is almost always near 20 on the gauge.

 

[STREETRACER]

sounds like carbon on the valves! go to midas and get a bottle of REDEX octane booster, and go wack it on the freeway for about 20km.. very common problem if i car never sees flat foot accelerating..

redex is not to up the performance but it also cleans valves very good!

is that 320i a 6 Cyl?
That consumption seems normal to me..
Comparing to my 1992 E36 316i(1.8L 4cyl), 2000 E46 318i(1.9L 4cyl), 2004 E46 318i(2L 4cyl), & 2006 E60 525i(2.5l 6Cyl).

On the sluggish point I have no idea, try the REDEX & see

In my 2000 e46 2.3 I get about 15l /100 km, gets down to about 7-8 on the open road.

Do engine cleaners actually work?

 

[Barkie]

Thanks a lot all of you. Seems that the FC is within limits. I am however concern that the power on low RPM is a bit down. Power delivery between 5000 and 6000 RPM is very good.

i dont touch engine cleaners, do how ever use a bottle of injector cleaner every 30 000kms.. but on all lazy driven cars since back in the day i just flip in a bottle of redex octane booster and open up for about 20km it removes all the carbon on the valves, ive tested it with a cylinder scope.. there probably is stuff that also works well but the REDEX works and its only R28 a bottle!

@ Street Racer

how do you apply REDEX i think ive got the same problem too, open road its so light on fuel but city driving ud swear its a V8 it gulps and i am a lazy driver, engine hardly ever sees the right side of 4000 RPM so i think its the same.

 

[STREETRACER]

i add one bottle to half a tank fuel!

 

[e46 guy]

i add one bottle to half a tank fuel!

LMAO you see there i was going to add it into the engine directly :hammerhead: through the oilcap :hammerhead: would have had more issues then some carbon build up after that :cursin:

im sure there would have been directions on the bottle though thanks Clutchplate:thumbsup:

 

[andrewbuch]

UM dude clutchplate is a different person to streetracer

Its Monday Please forgive me Streetracer im so sorry

just for that i give myself :slap: :slap: :slap: :slap: :slap: 5 slaps to wake the F up.
I must have had a bowl of blonde for breakfast

Once again sorry

thanks Andrew, I hope im not Streetracers hit list now

 

[STREETRACER]

whoaa lol i read your post but thought you thank'ed clutch for something else, he is a very helpfull mate and not funny to hear some one thanking him.. LOL bowl of blonde sounds like my type of breakfast!

That seems about right for a 320i, i get similar consumption. Any spirited urban driving and the cosumption goes right up. On the open road its quite economical.
the e46 320i is sluggish below 4000rpm.

I was having the same issue with my E90 320i.

Took it to BMW, the removed and installed air cleaner.

On Weekend when going to Rustenburg, i was getting 7.1 avg spd 140km/h(Cruise Control). But in the city i m getting 8.0.
