Hi Guys and Gals

I posted a message on here not so long ago about fuel consumption. Well mine has certainly improved...........today on the way home from work it told me i was achieving 99.9mpg..........and then as i was going down a local by-pass, the computer read 78mpg. I think the computer may be lying slightly Has anyone else had any trouble with the computer readings? All the other readings are okay (average speed, miles till empty etc...) I'm sure my ST has a mind of its own

Cheers, please let me know
Sam
