#11 of 311 1000 miles by hyybrd Jun 16, 2005 (6:54 am)
My mileage is increasing. No trips only local driving approaching 25 mpg. These are mostly short trips by my wife as this is her car.

2500 miles, half highway, half city, 24.9 mpg average.

1200 miles in 3 ½ weeks, probably 60/40 - highway/city, some long freeway trips, some short city trips, rolling slopes and very infrequent use of AC: 28.2 mpg. We started out at 25+ mpg right out of the dealership and took some long freeway trips initially. We’ve hit 30+ mpg driving strictly city. We noticed that our manually calculated mpg is about 0.2 miles less than the computer’s calculation. Our salesperson told us if we wanted to save money but not hurt the car, we shouldn’t use cheap A--- gas but Costco cheap gas is okay. The acceleration is fantastic! Needless to say, we are very pleased. Replies to this message: stevedebi (Jun 17, 2005 10:18 am) andyux2 (Jun 17, 2005 8:36 pm)
#14 of 311 Mileage 675 by zoregoncoast Jun 16, 2005 (10:01 pm)
675 miles...first tank 24 mpg and the second slightly better at 24.5 .half city and half two lane Oregon coast highways..no freeway travel yet.,..hard to believe that one can get near 30 except in town driving.great acceleration yet feels like an electric bus when slowing down .. amazing technology to be sure..seamless interplay between the electric and gas motors..quiet..initially felt heavy and ponderous but that has faded..very comfortable. no regrets even if the mileage is less than stellar.

Texaco, Shell, Exxon/Mobil, Chevron.   You will pay for that cheaper gas later on, and the engine needs to stay clean to be efficient. I have found that Toyota's in particular need the cleaning fuels, and for a hybrid, having the engine at top efficiency is important, expecially since the engine stops and starts so frequently in traffic.

Replying to: stevedebi (Jun 17, 2005 10:18 am) Thanks for the tip on gas. We'll certainly keep this in mind with our new car with the different technology that we've been used to driving. We just sold our '83 Supra for $100 to our mechanic who coveted this car for years. The engine was still in great condition after 250k miles. We had to sell it because the fuel injector was starting to leak all that cheap A--- gasoline. We didn't want to have a fire. He said the cost to fix it (and other problems that were starting to show up) could be several times more than the value of the Supra .We sure like the huge improvement in fuel economy with the 400h. We won't be filling up as often so we just may use the better, more expensive stuff.
#17 of 311 Mileage from 400h Test Drive! by briegel Jun 17, 2005 (9:29 pm)
I test drove a 400h today for about 30 minutes and about 17 miles. The drive was about half freeway at about 60-65mph and half suburban street driving at 20-40mph. This was in the Bellevue-Kirkland area of Washington state, in 70 degree sunny weather without using the A/C. I reset the average mpg at the start of the drive, and ended up with a 29.1mpg average! I would guess that my 2005 AWD RX 330 would not have done any better than 18-20mpg over that same drive. I was quite impressed! Replies to this message: stevedebi (Jun 20, 2005 11:55 am)

Replying to: briegel (Jun 17, 2005 9:29 pm) One has to be careful of the displays; the only true test of MPG is the good 'ole "fill it all the way up and divide the miles driven by the gallons used" method. The gauges can be deceptive in the short term.
#19 of 311 Re: Lexus RX 400h Owners: Report Your Mileage [KarenS] by mirex Jun 21, 2005 (9:25 am)
Replying to: KarenS (May 06, 2005 6:47 am) After 775 miles I am averaging just over 29 mpg. 85% highway and 15% city. Air conditioner was off 80% of the time. I tend to use cruise control whenever it is safe to do so and my maximum speed has been 60 mph.   The first two tanks were premium and the last 87 octane and I have not noticed any difference in mileage or performance.   In a couple of weeks I will be leaving on a 2,000 mile road trip that will take me from sea level to a high of 7,500 feet. I generally set my cruise control for the posted speed limit so I will be cruising at 60-70 mph with short higher speeds while passing. I will report back after the trip.
#20 of 311 fuel consumption by dmbflorida Jun 21, 2005 (3:47 pm)
on my new RX 400h, I am on my second tank of gas, now at 300 miles total so this is not enough time to really know what my mpg will be. Note: I filled up early. However, so far, it is about 26 mpg in flat, hot Florida, with very short city trips with A/C running. I expect better in more favorable circumstances.
