nightrider2000 Posted March 3, 2012 Share Posted March 3, 2012 Hello I have a 2011 RX350 with 1100 miles. I noticed my mileage has dropped 0.1 mile every day in the last two weeks. It went from 17.8mpg to 16.5mpg. Is there any ideas or suggestions? :cries: thanks Quote Link to comment Share on other sites More sharing options...
SW03ES Posted March 3, 2012 Share Posted March 3, 2012 It all depends on your driving habits. For instance if you've been highway driving and then drive around town for a few days, the average mileage will drop little by little as each day goes by because you're obviously getting lower mileage around town than on the highway. My guess is thats the issue. Welcome to the LOC! Quote Link to comment Share on other sites More sharing options...
LEX-SV Posted March 15, 2012 Share Posted March 15, 2012 That much mileage variation is not unusual with varied driving conditons. Based on mileage reported, you must be in a urban area. btw - Welcome. Quote Link to comment Share on other sites More sharing options...
The G Man Posted March 16, 2012 Share Posted March 16, 2012 If you are using the on board computer for milage calculation, then that is normal. It always starts out high after a reset and goes down slowly afterward. The on board MPG computer should be use for reference only, manually calculate your gas mileage after each fill up for a more accurate MPG average.
