When I picked up the Ovlov a month ago the trip computer said it was doing 55 mpg!  :y  It's now at 46 mpg so I assume the previous owner coasted everywhere!  ;D

However a brim to brim check last week worked out at 35 mpg...  :-\  Why are these trip computers so inaccurate?  ???  :-\  ::)
Because the speeds are set to over read... Screws the mileage calculations ;)
Reset ALL the trips and try again, and you'll find it nearer 35mpg rather than the lifetime averages  ;)

I would say they are deliberately manufactured to be 'optimistic' because manufacturers  know that most people can't be arsed to do a brim to brim test.


Jag Trip computer is about 20% optimistic.

Yep, the manufacturer published figures are optimistic, so the readouts have to match.

Nope, the speedo is set to display over, the speed signal is actually pretty accurate  :y

They are usually ok over longer journeys, its short journeys and lots of stop/start where they are not good

My astra is reading 46.5mpg. Last time I tried the brim to brim method, it worked out at around 44, so not that far out.

In order to get 44 MPG out of anything a person would need to drive around like a doddery old fart......Oh hang on..... :)

Not so. Average figure quoted is around 50, and I certainly don't hang about.
