Nominally the computer can't be trusted because we are all finding it's inaccurate, but regardless whether it is absolutely right, the reducing trend is about the same as I get if I calculate mpg manually.

Is your 53 per computer or manual calculation?

After weeks of getting 52 on esso normal diesel I decided to try some shell super diesel. On my first commute today, with normal traffic conditions, I got 63mpg.

(My commute is long enough to make the effect of a cold start insignificant)

Interesting.

Let's see how the rest of the tank does.
