Topped up the tank today and the calculated figure was a pleasant 61.4 mpg (Fibometer 63.6 mpg). I decided that since petrol is at the cheaper end of the scale, I will fill up with 97 RON today. £1.107/litre. Almost the entire fuel was used driving into and out of Edinburgh. With the traffic as light as it has been that was a joy rather than a penance.
One of the benefits of such sparse traffic is the ability to slow down at my discretion. There are several gentle descents to 30 and 40 mph limits where with no following traffic I can take my foot of the accelerator and allow the Deceleration Fuel Cut Off to shut off fuel to the injectors. I arrive at the limit, at the posted speed, without having to brake. In traffic, I have to use throttle until much closer to the signs and then use a little light braking, wasting fuel in the process. Over a tankful of petrol all these little things add up, giving numbers I would typically only see in mid-summer.
