Well I had to get a 2 Litre Triumph engine transported 180 miles and my only tool was my Quantum 2+2 and a 5ft x 3ft trailer that had no cover on it, hence an aerodynamic brick!
I brimmed the tank and sat nav and speedo were used to find out what my standard Weber carb XR2 engined Quantum got to the gallon. Wow 37 mpg dragging engine up and a staggering 43 mpg on return journey still with the trailer and no cover but empty.
What mpg do others on here get?
Cheers
Jon

When I checked mine (several years ago when engine was still new) I got 49mpg on the Stoneleigh run and return. I haven't bothered checking it since. I add that I ride a pedal bike, and drive in a similar manner, so I  don't drive hard on the brakes and accellerator - going up hills seems so much easier in a car!

Mine was around 20mpg but it’s not quite the same spec....

I have to add I use the limit.............to the limit in as much as 60 MPH whenever possible and acceleration is let the engine spin on a light pedal.
My turbo 2+2 struggles to better 30 mpg but then again that woosh of power is corruptive!

If the weight of an engine makes so much difference it might be interesting to know how much difference it makes when Jon drives with and without a passenger (adhering to the same limits as he would have done with the trailer).

Using a well known diesel powered estate car I towed an aerodynamically styled enclosed box trailer containing a table and six chairs on a 200 mile trip.
The contents which were carried on one leg of the journey, seemed to make no difference but the trailer increased the fuel consumption by about 40%.

Wow I only get about 23/24 in standard CVH Weber dft setup (although I am saving up for a shiny new carb....)

Be interested to hear what Rob is getting from the 2.0 Zetec turbo. I've had 20ish when going on lots of fast short journeys, and over 40 on the Ireland tour. 

MPG is so variable on driving style. However you carb boys are already at a disadvantage economy wise. Either way a smooth driving style with little braking and no harsh full throttle acceleration will net higher mpg (kinda obvious). From my 3 litre petrol 320bhp everyday car I can get mid 20s around town and racing away from lights. My best commute (35 miles) being ridiculously careful I got  48.9 mpg. Normal daily average on commute is 39 (5 miles town, lights and roundabouts, 30 miles stop start motorway) Not bad for a car that on paper gets 37 mpg.   Point being without lab conditions it's pretty hard to compare one car with another when there is a different driver at the wheel.

Hiya

Q2-002 with Carb and 1.6l XR2 engine did nearly 50MPG when we went to Hastings from Birmingham (200 miles ish each way!) last year - that was with all the clothes etc for a weeks holiday.  Normal running average is 25-30ish, but if I only run to work and back (2.5 miles each way), I only get 15-19MPG.  The heater just starts to get off freezing as I pull into the car park...  I have also got a K&N air filter and stainless exhaust fitted. 

BTW - only 600 miles to go before the odometer goes to 00000.

I have to say that the Zetec turbo can be quite frugal if driven with a light right foot. I never really work out MPG but the run to Stoneleigh and back last year was relatively painless in the wallet. I did  have the speed/ acceleration limiter installed (otherwise known as my wife). In general though, it's a toy to be driven quickly, so fuel consumption isn't a consideration. If I'm out with guys in 7s, fuel stops are usually every 100 miles or so and I just top up when they do. Hoping to do a trip to mid west France this year, so I'll have a good chance to monitor fuel consumption. Google maps says its 951 miles one way, so will be over 2K miles with some running about over there.

You must have a problem or a mighty right foot.

Ha ha, I actually have a little nag commute and a tight budget, a couple of colleagues have the same Astra 1.3 diesel (company car) as me and I regularly hit the 70s but they struggle to get out of the 50s. That being said - when i do get a new carb.... Vroooom!
