Fuel consumption

[__iceman__]

Just got my car (325ci) weeks ago.

haven't driven that much yet. Car is completely stock standard, riding on 18" BMW rims.

This morning I just topped up my third tank of petrol. Following is my FC record:

1st tank: 7.21km/l
2nd tank: 6.1km/l
3rd tank: 6.39km/l

Driving pattern is 90% city traffic, 10% highway. Can the other 325 owners here verify if this is normal?

What can I do to reduce the consumption? I recently added the Simota Aeroform intake, car feels lighter now.

This may be a car that was driven very gently by the previous owner... my mechanic also commented that the sluggishness may be due to carbon buildup inside... "seldom whack".

Suggestions of whacking on NS highway to clear carbon is out of question coz I don't want to go in just for that. Can I have show of hands and report of what you guys are doing for consumption?

Where you buy the Simota intake? Price?

Iceman,

Are the fugures above based on your reading off the OBC or based on mileage clocked (as reflected in odometer) and divided by litres of petrol pumped (as shown at petrol pump or petrol receipt)? Coz I can assure u that the OBC is absolutely inaccurate. If u take the reading off the OBC and match that against your petrol receipt, alot of petrol wld be unaccounted for.

I am driving an e39 525i (same engine as yours) and my FC is abt 6.5km/l to 7.2km/l. I do 80& city and 20% highway based on odometer/petrol receipt formula.

No no, its always mileage clocked divided by litres pumped.

I have been doing this for years... always top up to full tank, and remember to reset the odometer before driving off.

Well... your figures are within 10% of mine - better though.

Anymore 325/525 owner feedback?

Talk to fellow forummer - Rex7_Vtec. He'll show you.
