You can use either but it won't change your mpg unless you happen on one with less ethanol in it. The ethanol lowers mpg by up to 10%. Sometimes you can luck into a blend with less ethanol. That is the only thing that will help mpg. We have all been had by the corn guys.

I seriously doubt the premium fuel contributed much to that. The gas mileage is a selling point manufacturers like to brag about. If using premium gas would increase the gas mileage Lexus would have claim the higher number and not change the recommended fuel to 87 in the 2013 rx 350.

My 2013 RX350 (7500 miles) is getting about 23.5 mpg on the interstate, at around 75mph, using regular gas with up to 10% ethanol. Local driving has too many variables to evaluate.
On a related note, I have run the tank down to the low fuel warning twice. Both times it only took a little over 16 gallons of gas. Does that sound right?

Yep, sounds about right. Have never put 16 gallons in my RX yet and I have run the cruising range number down to single digits. There is a great deal of tolerance built into the system as a safety measure. Don't want you running out of gas because you did not see the light come on right away.

2014 RX350, ran till the warning light. Gas gauge showed one tick from empty. Fill was 16.2 gal. Dash showed 30 miles remaining. Avg on tank was 24.5 MPG. 80% highway. First fuel up on vehicle.
Since the gas tank holds 19.2 gallons, there were 3 gallons remaining when the warning light lit. I should have been able to drive another 60-70 miles at the current MGP rate. The fuel gauge showed one tick remaining which would equate to around 2-3 gallons.

Improving MPG ?
My 2012 RX 350 has had steady improvement in MPG! I now have 6700 miles and we went to N.C. from Western New York averaging 23.9 MPG. 87 grade gas!
Never expected to get above 22 MPG so I am very happy!

2013 RX non-Hybrid
Approximately 18K miles on it.
I just drove From North Georgia to Tampa
Average just shy of 26mpg's. What's strange the mpg's start to decline once I hit Florida; always does.
about normal for me??
