Doug9c1 Posted December 27, 2008 Share Posted December 27, 2008 You must be getting your mileage calculation from the happy meter (on-board computer). When I calculate it manually I average about 15.5 overall with 17.6 the best I have ever gotten. I drive 70-75 most of the time.

CujoX Posted December 30, 2008 Share Posted December 30, 2008 I recently purchased my 2004 GX470 with 51,000 miles on it and I avg around 250 miles per tank + or - but I do like when I fill up the meter says I have 330 miles before fill up, I don’t think it will ever be that good. But I’m in Denver Colorado so maybe the altitude makes a difference. Quote Link to comment Share on other sites More sharing options...

The happy meter gives 17.5 while actual calculations bases on fillups give 15.5 . Why cant Lexus make the happy meter accurate? Quote Link to comment Share on other sites More sharing options...

No matter who the manufacturer is. Quote Link to comment Share on other sites More sharing options...
