When I got my 1995 NG900 I was told the SID mpg reading was not accurate. Not believing what I was told I decided to use it accurately. I always fill to the brim record the figures and reset the SID, I accept that pump cut off points can be slightly different. (If I owned a petrol station I would set the cut off points high so that I sold more!). Most of the time I use the same station and the same pump. I record the actual mpg and the SID mpg at each fill up and then reset the trip and the SID. Over ten thousand miles the actual and SID figures are very similar and usually within one mpg with the SID figure slightly lower than the actual. I am very impressed with the computers accuracy. Incidentally other peoples mpg figures are not usually worth considering as they are rarely arrived at accurately, such as I did x miles on half a tank!
