Just wondered whether my 23mpg / 230 miles per tank (until fuel light is constantly on) for a UK 1988 Alfa Sprint 1.7 Cloverleaf driven aggressively was unusual! What do you get in your 33's and Alfasuds also? I have noticed I get slightly more mpg with Shell Optimax petrol - but the extra expense may cancel out this benefit!
I get about 30mpg in my 33 Boxer 16V QV. That's about 270 miles to a tank. I tried the dearer petrol too and thought I noticed a difference in mpg, but it was probably wishful thinking... She's a thirsty one. My Doblo JTD does about 49mpg and I get a more reasuring 470 miles to a tank. Much better.....
On my 33 16v I normally get a fuel consumption of 8l/100km - 8,5l/100km, driving normally to work, sometimes acelerating hard (3rd gear to 150km/h) under overtaking...
Last week I've done a 7,5l/100km, driving pretty easy (not always... there is alway a truck to overtake )
Once I even got a 6.2l/km average when I went on holidays getting 690KM out of 43l, pretty nice
But when she gets thirsty shhe swallows up 13l/100km:
I always go on the trip meter rather than the gauge to determine how much petrol I actually have left - I know that when I get to about 225-250 miles I need to get petrol quite quickly! So I guess your experience is about right.
I did once manage 38mpg in a 95bhp sud many years ago. I was driving down to M4 to Wales following my then girlfriend at a steady 70mph, so better mpg is possible, but a bit boring!
I'm getting about 6.3lt/100km, on my 33 Series 3, 1.3 I.E. Very light driving, 100 km/h or less, on a hilly and curvy two lane highway.
Using the A/C, it probably drops to 10lt/100km. Anyways, they're pretty economical cars, they get about the same mileage as some of the modern TDi diesels out there, without the sluggish performance and nasty noise.
err, in the month before my engine blew up, i used to get 250 ks outta a tank of 98 ron optimax/synergy8000/bp ultimate...and that was driving to and from school...gently at that!! on the weekends it would drain a tank in just over 100ks...very expensive when 98 ron is about $1aud plus a litre
