Atlanta, HOT Atlanta, summertime....more use of the A/C...? I guess that could also be it, but I am talking about how you can see the range on the dashboard when you first fill up the tank...it wouldn't know before hand that I am going to make more stops or that I am going to use A/C would it? I figured that when you first fill up the tank it gives you the range that you should get and then once you start to use it and if you use A/C or are in more stop and go traffic that would cause the mileage to drop more quickly versus it just showing less mileage right off the bat. I don't know, but I guess it isn't such a big deal...I was just wondering. My main thing was that I wanted to make sure that I could use regular gasoline and it would not cause problems down the line with my car. Thanks for your response.

Okay that is what I was thinking. Thanks so much for your response. I will more than likely continue to use regular since it isn't such a big deal.

I purchased a 2003 Lexus ES300 6 months ago and since my purchase I have been using regular unleaded gasoline. I hear from a lot of people that I should use premium gas, but some people tell me it is okay to use regular. I haven't noticed any problems with the car, it seems to run smooth to me. But I have noticed that I get less gas mileage on the car in the last couple of weeks. Usually when I would fill my car up, it would give me a range of about 310 miles, now it gives me a range of 295 miles, does anyone know what could be causing me to get 15 miles less? I get the oil changed regularly, I might need to get the transmissions serviced. Any advice would be helpful, thanks.
