I just got my 2013 GS350 Fsport and I thought it was supposed to get a little bit better gas milage. I'm currrently getting around 16MPG using premium fuel. I was just curious what everyone else gets with the same car and also was gas you use someone told me I wouldn't do any harm using mid-grade fuel as well.

 

I use regular. 15.5 mpg. 80% city

 

I have a 2014 base model (non F Sport). I am getting 20 mpg and thats with a good amount of highway miles doing 80 mph. I also thought I was going to get better gas mileage. I thought it was going to be closer to 24 mpg

 

I have a 2015 Fsport with 6K miles and phew I thought I was getting bad mileage at 21 -23MPG. I drive about 50-50 in city and highway. I've only had my car since Dec and the car was built in AUG with little increase in MPG (probably 2-3MPGs).

 

My 2013 gives me 19-20 mpg in all-city driving (stop and go), and 27-30 in all-highway driving (cruise control set to 70. Premium fuel only (93) - my neighborhood has only 87/89/93 (no 91)

 

2015 F Sport gets about 16 MPG with Costco Premium. My commute each way is 1.4 miles.

I use the eco mode when I am in stop and go traffic and it saves me on gas. On the highway or straight roads, i put the car to cruise and keep it at 70-75 and it saves me even more on gas.

I was able to get from West Palm Beach to Key West in one full tank of gas. And thats around 250+ miles just one way.

 

If I baby the car I get about 22-23mpg and the best so far is 360 miles to the tank; thats with the computer reading 0 to empty and me not thinking I would make it the last 2-3 miles to the gas station. I would say I average on a day to day basis 16.5-18 mpg.

 

I have a 14 F-Sport with 42K miles and have never reset the lifetime mileage.

22.8 mpg. 90% highway.

 

My BMW X3 6 cal non turbo does better than that . it used to be that the Japanese were the efficient ones. BMW has blown them away in mileage. Traveled like you 90% highway for 6 months. Averaged 26-29 per gallon and that's with AWD.

 

My 2013 RWD F-Sport consistently gets 25-26 mpg in all-city driving (stop and go), and 27-30 on the highway (cruise control set to 75). I use mid-grade fuel and never use eco-mode. My city driving is in Tucson, not NYC, so some might characterize it as suburban. Traffic lights are as much as a mile apart. My 1994 SC400 got 2-4 MPG less than the GS under the same conditions.

 

I have a 2015 Premium with just over 8000 miles. I have been getting an average of 23.8 mpg according to the cars computer. I have a 25 mile each way commute which is 15 miles highway. Usually cruise at 75-78 mph.

I usually get between 23-25 mpg mixed driving 60% highway and 40% city. I average about 378 miles to a tank. Lately I've switched stations and now my average has dropped to 349 per tank. Also I have 20" wheels. Not the best but compared to some of y'all I'm happy with what I get from my car. When I was looking to buy my GS I would flip through the display settings on all the used GS's to see that particular cars current mpg average and some showed 16-18mpg. I looked at the one I have and it was showing 21.8 if I remember correctly when I picked it up. I know those numbers can't be accurate as that car could have been sitting idling on the dealer lot before I got there but I was surprised to see the different ranges.

 

17.5mpg mainly city driving
250-260miles per full tank premium
