How Juicy is your five? (Tank range)

lift the foot off slightly!!!!! and try resetting the OBC again and drive as eco as possible for a couple trips...Dont forget its been cold out there and i think that uses more fuel. How far are your journeys?

i get about 26mpg average according to the OBC, 70 litre tank gives... err... 390 - 400 miles to a tank ?   mostly a-road and b-road driving with minimal town work

6-cylinder 3.3 litre petrol, 5-speed manual

The other MPG computer I zero before a long journey. Most I've seen is 34mpg over a 300 mile trip to Cornwall and on trips like this I see approx. 410 to 440 miles to a tank. Cars a 523iSE with steptronic box. Will be interesting after this weekend as I currently have the proverbial stuck open thermostat! I'm changing it Saturday. During this cold spell the temp gauge barely leaves the stop and the computer is reading 22.9mpg which is low. I reackon it will improve but by how much?

i got time to change the stat (and yes it was totally shot to bits!)when I got home tonight and I've just been on a rough 20 mile run mix of country lanes and by pass up to 90 mph! Zero'd the computer which was reading 22.7mpg on mainly a similar type of driving. After the 20 mile run of my normal driving..........the trips reading 28.2mpg!!!!! 22.7 to 28.2 after just changing the stat! Can engine temp REALLY make that much difference? It certainly feels much free'er and smoother.

Well here is a turn up for the books!!

JUst reset the trip for a 40mile drive from Leeds to Blackburn. In rush out! (left at 7:50am) reset the Cons2 and on arrival it showed 31.2mpg!!! I am stunned as my TT would struggle to do the same.

This a 535i auto we are talking about. in fairly heavy traffic. lots of stop start and about 15 miles on the motorway. It bodes well for my long run down the M6/M5 to Taunton...

I'm lovin' this car more and more...

Well guys my 540 is averaging about 19-21 mpg if i drive with gusto that drops, the lowest i have seen is 7.2 mpg or gpm !!!! cant complain though its such a buzz to have all that power and effortless cruising and just think someone paid about 40k for it when new and still had to put fuel in  i bought it for 3k so can afford its drink problem although mpg is (much) better on optimax...23-28mpg

the 520 I has always done about 28 mpg the most i have seen is 35.6 on a run so when i feel bad about spending all that money on juice i take the 520 I....

Regards

ive tried to always use optimax wherever possible in all three of my bms (e36 318i, e46 323ci, e39 alpina) and i dont forsee changing any time soon, im that convinced
