So still wondering if my seicento is using to much fuel no leaks and I understand the mpi is batch injection therefore not so good when siting in traffic so I get about 30 miles per mark on the mk2 dash so just wondering what you guys get on a full or half tank ? Oh yeh I cruise in 4th nearly everywhere and had full service

you are in wrong gear for me if you "cruise about nearly everywhere" in the gear you are in

you should be in top gear as quick as possible when conditions allow if you want to cruise about and get a better mpg

i think ove had 380 miles out a Full Cinq tank ,, cant remember exact amount as it was a while a go since i drove it

I think I get around 250 miles per tank until the light comes on. 380 miles?

I'm in youkshire so hills and bends so I find 4th the most common gear for me saying that on motorway in 5th cruising about 65 to 70 so think may brim the tank and reset trip counter don't really do short jurnies over 10 miles in one go is the norm and I do drive quite enthustiasticaly

But the marks on the dash, due to the crudity of the device measuring fuel level and the shape of the tank are not equal. Fill the car up and you'll be amazed at how economical it appears to be until you get below the first mark.

The guage is only accurate when the tank is full or empty. In between, it's guessing. Fill up and see how far you get till the engine dies. (Carry some spare fuel in a can for the last part of the journey).

No need to run out of fuel. Fill tank, note mileage.

Drive 100 miles or so.

Refill tank, not mileage.

Do calculation.

Check tank seam for dampness

Report back.

use fuelly...
don't run the tank into reserve light on Fiat does not recommend
40 to 60 mpg note the 60 is London to Glasgow at 60 mph on M way

Last time I did a fuel check our 899 Sei was doing 58MPG. That was on a 150 mile motorway run though.

Ian.

Just got over 1/4 tank left, and my Cinq has just done over 230 miles...probably squeeze 240-250 by the time it reaches the 1/4 mark.. and that's with the tuned engine and majority town driving. If I were to drive to try to save fuel....I could probably get at least 300 from 3/4 tank.

so if it turns out mine is being to thirsty i may just downgrade to spi got loads of bits for spi as well oh and was on the phone to the bog brothers again
but due to the wee bump that will haft to wait

Never seen that myself.

Had 350 miles out of mine once.


Once.

All spi's seam to have better resalts compared to mpi but apparently mpi is nicer to drive but is this compared to spi with or without mkritch or gazman2k ?

Who knows? Much economy is about driving style, rather than anything else.

If you think you have fuel consumption issues, try a Volvo T5.

MPI cars tend to be a little smoother, perhaps a little quieter, but to my mind a Cinq is nicer to drive (except for pizza delivery) than a Sei.

Well i have used another mpi sei (onto the drive) but the idle was the same as mine quite lumpy but pulled well but have experianced loads of spi centos and puntos although not smooth they are better than mine

or stick a turbo on your sei, 200 miles is about my sei's limit. But thats only on long constant speed trip it can do that, pretty sure you could empty it from full in under 100 miles

Couldn't comment on mpi vs spi to drive, never been in a mpi as the spi is clearly much cooler, and the sporting bumper looks so much more italian than the mpi bumper. It a no brainer to me

I get 55 mpg average on my 50 mile per day trip but it country road and motorway,thats in a sei 1.1 mpi and im hoping to beat 60 this afternoon when i do 150 miles mainly on motorway

I think going to Stanford will probably be the longest journey I'll have done in my seicento mpi and it will mostly be A14 all the way so I will find out if we can get 60+ mpg

Convoy with me, and if it's possible for you Sei to get 60mpg we will do it
