*** T.C FUEL CONSUMPTION (and let's be honest!) ***

Come on let us all be honest with go-go juice prices near the £5 mark,what type of millage do you get from your T.C. (H.L/GT)
From my own dealings i NEVER ever got more than 25mph even on a run (and driving at 55 mph) even in standard tune,from any of the models i have ever owned (and yes the carbs were correctly set-up and not worn) and the engines professionally tuned.
Ok i know driving styles make a big difference,but T.C ownership was not for me (the performance did not out weigh the economy) so i went "O" series,albeit via modification.
The "B"series is an old engine,old even in the 1970's when first fitted to the Marina a good engine,no less but from an other time,when things were very different to to day fuel consumption was not a priority,add to this twin carbs and you'll get the picture (alright and no 5 speed gearbox) so come on what do you get to the gallon? :roll:

The fuel consumption for me means I simply won't be able to afford to run a Marina TC as my daily car so my first car will probably end up as a 1.3. Could have a TC for occasional weekend drives :)

Getting 30mpg on my 80,000 marina 1.7HL
Not bad for a 28 year old car.
I use this 1 daily to work and back doing around 220 miles a week.
Getting engine up to normal operate temp as quick as poss is a must so make sure good thermostat and even blocking radiator grille up a bit over winter.
also i think bonnet insulation may be a good idea,and electric thermostatically controlled fan(kenlowe) as fixed fans eat away at ur fuel compsumption.
The 1 like is the Kenlowe hot start but costs a bit so u have to way this 1 up.
A warm engine uses less fuel than a cold 1!!
Best regards

Anybody who says they get more than 28 mpg in a standard T.C., is in cloud cookoo land, despite having a brand new B series, ( yes a new one) and brand new HS4 carbs, set up on a rolling road, the most I managed to achieve was 27 mpg ( at 50 mph on a run ) , compare this to the same driving technique as applied to my Dad's 1700L estate where 42 mpg was the result!.
1800 T.C. nice exhaust note, but not fast OR economical :roll:

The B series engines, so poor I swapped mine for 1300's/1700's


Beckett Brothers, just too uneconomical by far :(

Mk 3 1700 HL 82 BHP & 39 mpg :D as opposed to MK 2 G.T. 85 BHP & 26 MPG :(

Not too sure that you would need a rolling road to set up your standard cars Brian.. Me thinks you may be talking cookoo mate.. Most people make do with a good ear, strobe and colour tune.. or am I missing something..



SLK.. If you want economy from a TC fit a modern engine - "Just to powerful by far!"

Don't forget the correctly setup engine too Sam! New dizzy, points and condensor.. my word we will have to invest in a rolling road! LOL!
