Not Happy with MPG
- Thread starter supersebbo
- Start date
I did 212 mile return journey yesterday (in my 28i) over motorways, A-roads and twisty b-roads and it averaged out at 39.2mpg overall for the entire journey.
I wasn't exactly hanging around either! Gave it a proper hooning on the B-roads which was brilliant fun.
I'm finding the mpg is just getting better and better the more miles I put on the car (done 1730 miles in it now).
I really am finding the 28i engine to be one of the most versatile and rewarding engines I have ever had the pleasure of owning in a car.

Thanks, surprising that you got better MPG in sport as I thought it would drop drastically. Looks like it's time to have some fun
Driving to Birmingham from Sunderland tomorrow so will set the computers to zero and try using cruise control set b/w 70 & 85 as much as possible and post the figures. It's about 95 % motorway so should get good MPG. It's forecast to be a nice day so will try most of the journey with the top down and compare with the top up coming home and see what difference that makes aswell
So we are all seeing higher mph in the 28i as its getting near 2K.
Will be interesting Nanu, I think the top down improves it possibly +3 mpg benefit?. Dont forget to put the AC off and fan speed to 1.
I have gone back to shell today but the mpg seems to be still up, 44mpg on each 21 mile trip and even going the more fun hilly b road its doing 44 which would have taken 4mpg of the 30i pulling this down to 27mpg.
Gonna pop sports button on and see ho it fares.

I have been running an E89 3.5i twin turbo double clutch transmission Z4 for a year now (the car is now 3.5 years old and has done 28k miles). Before that I was running an E85 3.0 Roadster auto (again over 3 years old and low mileage). The E85 returned 21MPG, regardless of how it was driven. The E89 is returning 23MPG, again regardless of how it is driven. I realise these are low figures and may indicate that I drive quite aggressively but 'going steady' doesn't seem to improve MPG for me. I have tried using 'a light foot' on route to London and back (260 miles) and the MPG was the same (I reset the measuring system to check). I also keep all the ancillary equipment turned on, like air con, etc (why would I want to suffer?). In summary, I am OK paying the petrol bills given the delight I have in driving the car every day, and accept that this is an expensive hobby!

In summary, I am OK paying the petrol bills given the delight I have in driving the car every day, and accept that this is an expensive hobby!my 3 e85 2.5 were the same, I never really bothered about mpg as it was very close if not better than all the other cars. Sports mode, fast, slow ron97 nothing, just 32mpg.
It was the 30i that made me sit up a bit and have a look at different ways if I could save if not ill drive it. 26 was a bit concerning especially according to specifications it should be +2 up on my old 2.5's at 34 not -6 mpg worse. Got it up with a bit of fun to just under 30mpg.

Sunderland to Birmingham 95% motorway with cruise set at 80 and about a 10 mile stretch at 50 (for those damn speed cameras) and some conjestion near to end of journey, roof down all the way. Result average speed was 68mpg at 39.8 mpg.
Return roof up, aircon on set at level 2 foot hard down at every opportunity which was often except for that 10 mile stretch at 50 again, average speed 74 at 40.4 mpg
Read into those results what you will but basically the MPG is about the same no matter how you drive it so just enjoy
.Its hard to go by the obc, Im getting stupid numbers today starting in the 20s and went all the way up to 52.4mpg, with the roof down on a 21 mile run. I am unsure how the computer calculates it, if its the average over 16 miles then I will loose the lower initial mpg.
But its strange that we are seeing increasing mpg's.
The killer so far is town cold driving, but once engine is warm, economy is there whatever I do, all way higher than the 30i. I never saw 40's in this and actual hard empty to full averaged 29.5 over the 20 months I had it.
Im on for another 37mpg clocking up 303 miles with 8 ticks/ 1/3 tank still to go.
What I have sadly worked out is the volume of the tank in l v tank level.
Each tick is around 2.2l.
Filling up my zd from 0.5 to full was 50l. (this left 5 l as reserve)
It will not go below 20 i.e. full for around 60 miles which works out to be around 6l.
so at level 20 is 44 liters. 2 ticks works out to be near a gal going from 20 to 19 in 20 miles = 40 mpg.
Its very linear but needs to be measured on the flat.

Drove from Sunderland to Carlisle a distance of about 80 miles each way of 50% dual and 50% twisty stuff with limited overtaking but foot to the floor when the opportunity presented.
Outward with roof up and steady driving 38.7mpg. Return with roof down and sports mode all the way and enjoying the drive if you know what I mean, returned 40.5mpg??? Interesting thought that sports mode increases MPG.

The more I drive this beautiful machine the less I worry about mpgronk said:
I had a Capri 2.8i in the fabulous 80s (V6 Cologne lump was sweet) and can confirm that if I tried really hard I could get the mpg to dip well below 20 with best mpg being mid 20s. Of course in those days speeding was legal, no-one wore seatbelts, smoking was compulsory and you only got breathalysed if there were half a dozen empty lager cans on your back seat. I believe my Capri had around 750bhp although the manual stated 160 iirc.

The 2.8 was the later updated posh engine with fuel injection I believe ?
They had come on in leaps and bounds since I had mine in '74
Indeedy it had state of the art Bosch Jetronic (mechanical) fuel injection! Similar to the early Golf GTi injection system. Still one of the nicest cars I've ever driven! OK off with the rose tinted specs and off to bed for me! :wink:
