Road Trip MPG - 2013 Lexus GS 350 Long-Term Road Test

2013 Lexus GS 350: Road Trip MPG

June 27, 2013

2013 Lexus GS 350

Last September, when our long-term 2013 Lexus GS 350 was brand new, I grabbed the keys to the sedan and drove it from Santa Monica to Palo Alto, CA and back. The total trip was 727 miles and I averaged exactly 25.0 mpg on 91-octane premium fuel. (The EPA rates the GS at 28 mpg on the highway.)

Today our Lexus is fast approaching 20,000 miles on its odometer. It's well broken in. So, I thought it would be interesting to redo that first road trip and see if the sedan's fuel mileage has changed.

Last week, I drove the GS from Santa Monica to San Jose, CA and back and once again I used 91-octane premium fuel as Lexus requires.

This time I averaged 24.8 mpg. How's that for consistency?
