Fellow LS460 owners .. I'm trying to get a feel for what NORMAL fuel economy is on the LS460. I've had my LS460L for about a week, and I'm not getting close to the published MPG ratings are.

Thought I would try to get a feel for what others are experiencing.

Here's my specs:

Current Mileage: 386
City / Hwy: 50/50
Avg MPG: 16.7
Driving Style: Lead Foot
Fuel Type: QT Premium

 

On the first full tank (dealer's fill up), 21.7 MPG on the trip computer. I didn't do a hand calculation to verify that. Probably a 40/60 mix of in town and freeway. This engine is only turning about 1600 RPM at 65 MPH.

 

First tank, 16 to 364 miles--20.0 mpg
Second tank, 364 tp 723 miles--21.6 mpg

Premium gas
Probably 70 highway
Driving style: easy on the accelerator

 

That right there might be it.

Isn't that cheap gas? Might want to try a more reputable brand like Chevron, Shell, or BP.

 

Yeah, driving style makes a big difference Mileage should improve some as car is broken in more also . . .

 

I've had my black/black SWB fro @ a week...just got back from 1,000 mile road trip..averaged 27.5 mpg...mostly freeway driving.

 

Well, there's your answer.
