Also own a 184 (SC) and achieved a lovely average of 59mpg on my last refuel stint. Think I got about 570 miles out of about 47 litres of fuel. Managed 64mpg on a 190 motorway trip from Darlington to Shrewsbury! Loving the combination of economy with great power!
I'd suggest tracking it properly as the cars trip computer can be a slight bit optimistic! I reset my trip when I picked up my car and the mileage trip and the cars actual mileage counter have gone up at different rates... Weird!
1 Rev counter (with the engine running, in hundreds of revolutions per
minute).
The beginning of the red zone of the rev counter indicates the maxi- mum speed in any gear after running-in and with the engine hot. How- ever, it is advisable to change up a gear or move the selector lever to D (or lift your foot off the accelerator) before the needle reaches the red zone.
Running in the engine
A new vehicle should be run in over a distance of 1500 km (1000 miles). For the first 1000 km (600 miles) the engine speed should not exceed 2/3 of the maximum permissible engine speed. In doing so, do not accelerate at full throttle and do not drive with a trailer! From 1000 to 1500 km (600 to 1000 miles) you can gradually increase the engine rpm and road speed.
During its first few hours of running, the internal friction in the engine is greater than later on when all the moving parts have bedded down.
How the vehicle is driven for the first 1500 km (1000 miles) influences the future engine performance. Subsequently, also drive at a moderate rate, es- pecially when the engine is still cold: this will lead to less engine wear and tear and will prolong its useful life.
You should also avoid driving with the engine speed too low. Change down to a lower gear when the engine no longer runs “smoothly”. If the engine revs too much, cut fuel injection to protect the engine.
hopeing to get around 45 on the motor way from what i have read on here for the 1.4 but just out of interest how much does it cost to fill up ? give a good idea of what each mile will cost then
