JMSTAMU Posted September 23, 2004 Share Posted September 23, 2004 I have an 04 IS300. The milage is 18-19.5 mpg in the city. What can improve the milage to make it more equal to other cars of the same HP/displacement? I had a 98 BMW 528i, 21city/33hwy. Quote Link to comment Share on other sites More sharing options...

bartkat Posted September 23, 2004 Share Posted September 23, 2004 If you're getting close to 20 MPG in town and 25 MPG on highway with an IS300 then you are doing just fine. Quote Link to comment Share on other sites More sharing options...
