The short drives bring it down and this is common for the 95-97's. If I do an all in town stop go I get similar to what you posted. Getting the car out on the highway for hours on end the V-8 does pretty good and the 98+ more so. Lately ours does about 350 MPG/ 563 km/g to the 1/4 fuel level line. These commutes are are typically 30-50 miles.

Fuel mileage
So i have a 99 LS400 I've been averaging 24 mpg combined city/highway if i'm just city I get 21 mpg this week I was on the highway for a good run I got 31mpg I don't let the tank get below 1/4 before filling it up and the computer resets each time. I don't drive like a grandpa but I dont beat the crap out of it either. The last tank I got 23 mpg combined with several high speed runs on the highway (over 100 mph) usually i drive between 75-85 on the highway. I only use high test gas and at this point the car has just over 90k on it.

I am mostly on I95 but yes I see I91 often, I've been driving the same parts of the highway for a long time I know most of the places the popo hide. I think because I don't punch it from a dead stop and mostly just drive faster is why my mileage is still good. Plus the fact i've just done a ton of maintenance to it. How often do you make the trip back and forth to Mass ?

Welcome to Club Lexus.
The same driving practices apply to this as any other car with attempting to get the best MPG as possible. Depending where in CA you are getting good MPG in LA is not going to be strong point in the stop go traffic commutes. Get the car on the highway at 65-70 will be the nice spot on long trips. Keeping it in good running order, using good gas and not having excess weight on-in the car.

I've been averaging over 25 MPG on the highway and around 18 in city driving. I think that's pretty impressive for a car this size and with this much power. My 07 Z06 got around 6 MPG in the city.....
