I seem to be getting stupidly low figures for consumption regarding my engine. The 1.1 on the 206 should be able to get around 55-60mpg, but recently I've been getting around 31- and that's not driving like a total nutter. I generally shift around 3,000rpm, and keep speed as constant as possible. A friend of mine gets 450 miles to a tank (same size) for his 1994 1.4 8v Astra, another friend gets about 270 miles to a tank for his MX-5. But my car seems to have an inability to get above 330 miles to a tank. Any help would be appreciated...
