Hi All,
I checked the tyre pressures on my new car and they were lower than the placard, so I took them to 37F/33R. The ride was awful! It seems the former owner (who drove track cars, and had just bought a Clio) knew a thing or two, so I dropped it back to the original 35F/31R. This is the first time I've ever come across a car with high placarded pressures.
The lower pressures certainly don't affect fuel economy. My first "proper" fill, where I'd worked out how to reset the trip computer, gave me 6.0 l/100km. The car reading was 6.3. The second fill gave me 5.7l/100km with a car reading of 6.2. I was astounded, because while there was little town driving in both tanks, the second included long sections of 110km/hr zones which used to kill economy in my previous Fiesta. It's also a bit odd to have odo/fill figures better the trip computer. My Koleos is regularly 0.5l/100km optimistic.
Those economy figures are on E10, too. The previous owner said he'd only ever used 95 or 98. The "Trip 1" in the trip computer was stuck on 9999kms and 8.8l/100km, which is pretty ordinary economy but it was a city car previously, a shopping trolley. It took me some time to work out how to reset it (you have to be stopped, for one thing).
Not only do I have a quick, nice handling and comfortable car, but it gives me superb fuel economy. It's many years since I bettered 50mpg
