405 mpg

hi

i am recently getting poor mileage from my 405 1.9 td is there a easy way of
establishing what is causing it or could there be various factors

What mileage ar you getting from it ??i have a 405 and i put £10 of
diesel in and getting about 100-150 miles .(no heavy foot)

 

if your getting 100 to 150 miles on 10 quid of diesel I would say you are
doing bloody well
as diesel is around £1.30 a liter which is works out as 4.546 liters to the
gallon UK
so at £1.30 a liter for £10 you get 7.69 liters,or £5.90 a gallon therefore
if you are only putting in £10 then that only 1.69 gallons
so if out of that you are getting 100miles then that works out at 59.17
MILES PER GALLON,
or if you can stretch that to 150 miles out of £10 or 1.69 gallons then that
88.7 MILES PER GALLON
if its the latter that you are getting then I would suggest that you keep
the car for ever, or your odometer is way out .

You're right. It's an impressive result.

I think Chris omitted to tell us that his car is fitted with pedals and a
windsail.
I average about 44 mpg with a 02 406. I did manage to get 48 on a trip from
Winchester to Liverpool last year.

I dont use a heavy foot when driving,also i change the oil plus all the
filter every 4th month, which helps in running,they say if you look
after the engine the engine will look after you. in my case that is
true.

 

heavy foot or not I am 100% sure that you are not getting 88.7 MPG,
no matter even if you changed the oil and filters on a daily basis.
Unless your journey is always down hill with a following wind and you switch
off and free wheel down it, but then that would mean an uphill journey all
the way back.

I get 44 to 48 mpg from current 405 TD and the last one.
Might do a bit better with a lighter foot, but only a bit.

 

That's pretty close to my 406 HDI 110 which gives 47mpg irrespective of how
or where it is driven. i.e. a heavy foot or town driving make absolutely
no difference, still averages 47 and has done since it was built in '99.

 

Eh? I can tell you for sure that a constant speed of 100mph in a 110 HDi
results in fuel economy below 30mpg...

 

Admitted I dont gallop at 100mph but before I retired I did a lot (30K per
year) of mainly motorway driving and since I retired at the end of 2002 my
travelling has been mainly local roads with occasional trips. I had to
maintain a spreadsheet when I worked which, amongst other things, monitored
average MPG and I have kept it going ever since. MPG has always been
within a few decimal points of 47.

 

Those are some figures for the 405, didn't realise the MPG was so great
