My Rb20DET around locally used to pull a consistant 470km's per tank.

All were short trips hooning to Uni and back.

Check the O2 sensor, Ecu's coolant temp sensor, dirty injectors and apparently the AFM can also cause bad fuel consumption.

Dropping the RB30DET in dropped fuel consumption to 430km's per tank.

The base map of the PFC has now bumped fuel consumption to 520km's per tank.

Leech, I fill up around the same as you. 50-55litres depending how low I run it with the light on.

 

Generally 50litres is pretty spot on with when the fuel light comes on.

yea strange i might be mistaken but i though my late generally comes on at around 46 - 48L which seems very early but meh fuel level gauges are always so dodgy i just go off how many kms :D but my car is also fairly stock at the moment only thing is a full 3" turbo back exhaust when i put the panel filter, bleed valve and fmic on i can see it dropping a bit hopefully not alot though

better fuel economy in Rb30det because of lack of throttle usage...im quite happy most of the time putting around off boost....it has the same feel as the rb20 did on boost :D

    • Wow ELVIS. You have an....interesting approach to conversation. Did you not notice that I wasn't talking to you?
    • Hello Liam - HA - somewhere in flies - possibly I have an update, but I have been so busy, projects have taken a back seat to getting business back on track.  I will let you know the outcome, but I think I am going to go for the 8HP,  CHEERS.  ELVIS
    • Thanks Joshuaho96, yes - as someone else also suggested, the 8HP seems the 'smart choice' - HA - and ZERO to do with cost, but I am sure 8 speeds will be better than 6 speeds - HA - maybe.  I will purchase a new 8HP,  Thanks.  ELVIS.
    • Nobody said anything about getting a "...cheap Falcon box..."- it was JUST a question about a specific transmission.  And YOU may have a problem with not enough $ - HA - I do NOT - so please keep your comments like you are some financial guru to yourself.  BUT - much appreciated re the cost of a new 8HP and I twill probably be the way I go.  Thanks.  ELVIS.
    • Most people I know in the BMW world are swapping 6HPs for 8HPs. The 6HP has a big issue with one of the clutch drum bushings wearing out shockingly early which leads to them going into limp mode going into 5th/6th gear as the oil pressure loss from the worn bushing causes clutch slip. Even with the adaptations in shifting the TCU can't bump line pressure enough to keep the clutches from slipping and burning. I've personally looked at a 335d with 6HP28 with one owner and ~90k miles on it and the transmission adaptations were way out of spec and even though it nominally drove ok I'm confident it would have needed a full rebuild sooner than later. Other than that they're fine, but the 8HP doesn't really have weird issues like this to my knowledge and they're in everything these days so pulling them out of crashed cars isn't too hard.
