which drive route is best?

[Phil_beeza]

i have the option of 6 miles of stop/start roundabouts (about 6 roundabouts with dual carriadgeway and traffic jams in between, so tons of braking, idling, shifting forward 6 feet at a time, and flooring it). this is 6 miles there 6 miles back

or 9 miles (9 there 9 back) of mostly motorway and 60mph cruising as my route to work.

any suggestions about which will be more fuel economic?

obviously the motorway will be better for the engine i guess (which is why I'm using it at the moment)

Motorway way. Less wear & tear too. + prob quicker

 

[m0rk]

certainly m-way

Motorway every time. Stop/start murders your economy!

Depends on which motorway! m25 or m20, forget it!

well clearly the motorway will be more econimical, but that not to say it uses less fuel.
ie due to the differences in distance. (30mpg on the motorway and 20mpg on the dual carriageways effectively the same amount of fuel used but the motorway is more 'econimical')
clearly if this is the case then the motorway is the no brainer, as there is less wear and tear. All be it will more miles put on the car.

if there wasnt traffic james on the dual carriageway then that would be the most economical, but as there are jams id say the motorway.
(is it the same both ways? it may be motorway to work and dual carriageway back is an option?)
