I just went through a full tank of premium (my first) and really drove like a granny. Not much stop and go traffic but not all highway either. I have a pristine 2007 L model. From what I gather on the forum, I've seen people getting 20+ miles per gallon in the city and 145,000 MPG on the freeway. (slight exaggeration). Should I be happy with around 18? That's actually a little worse than my old 2002 Q45 V8.

Thanks,

 

I got that with my city driving on my old 460. .usually 17.5 or so..highway road trips I would get 29mpg easy. My 600hL gets about 22 city

 

Sounds pretty normal.

 

yall r very lucky, in nyc i usually get around 12 and right now with all this snow its around 7.5 to 8.......crazy that this is the worst mileage ive ever had

 

if I drive 70 mph I get between 20 and 21, if I drive 60 mph i get between 22 and 23, at 55 mph i get 24.

in NYC I get 12 to 15 but I take it very slow.

 

That's about what I'm getting and I'm pretty happy about it. My Bimmer got far less. My average 50/50 hwy city is 22

 

I've hit 30mpg on the highway with cruise control at about 65mph over the span of several hours without a stop. In non-highway driving, 20-22mpg.

 

See that's what I'm talking about. cerbum gets 20-22 in non-highway. But it sounds pretty normal for my 18-19 so I'll not worry about it. I'm still driving the car very deliberately without too many sudden starts and stops. This car just calls for the smoothest ride possible. No herky jerkies.

 

I'm getting about 17 to 19 now with winter here. CO has a nanny-gate law that mandates all front-range counties use ethanol in the fuel...greenies don'cha know.
This always lowers the MPG by about 2 to 3 MPG during the winter months.

Summer months yield 19 to 21 around town.

Oh, and I usually use Regular, 85 octane. We can get away with it at 5,000+ feet elevation.

 

Same here in Washington. I get about 26 mpg in the winter freeway. Summer 30 to 31.

 

In winter, closer to 20. In summer, closer to 22.

I have a new 2014 LS460L with AWD with less than a 1,000 miles on it. Driving around town I note that the average mpg shows about 17.2 and that is using premium.

 

I think you should be very happy with 18mpg around town, 20-22mpg mixed and 28-30 highway only. Wonderful eight-speed transmission helps a lot.
Just enjoy the car.

 

I've had mine for a month now and 22.5 is the lowest so far.

 

I get only 10-12 mpg. City in my 2013 Ls460 f sport lots of stop n go on San Francisco streets.
