#62 of 64 Re: 2008 ES350 Octane Requirement [phili1263] by johnymack Jun 05, 2008 (3:36 am)
Replying to: phili1263 (Jun 02, 2008 3:22 pm) I have a 2007 ES350 with 11,000 miles and have been using 87 octane from the first time I have ever filled the first tank. I cannot tell any different and the car runs great with plenty of power. I absolutely love this car. My previous car was an E320 Benz and I drove that car for 5-years putting in 91 octane the whole time, right before I sold it I switched to 87 octane and was surprised to find out there was no difference. I was pissed that I wasted all that extra money for nothing buying 91 octane. When I bought my ES I asked the same question to the sales guy and he told me that his parents put 87 octane in their Lexus and have had no problems. I would not switch back and forth; I would pick one and stay with it. Same thing with oil, pick one brand and stay with that brand.

#64 of 64 Real World Gas Mileage for a 2008 ES-350 by turbobill Feb 05, 2009 (7:41 pm)
Now that my '08 ES-350 has passed the 20,000 mile mark, here are the carefully kept figures on gas mileage. After 73 fillups, the average is 27.4 miles per US gallon from a mix of probably about 50% highway, 20% urban and 30% rural driving. The best 10 fillups averaged 32.6 mpg (highway) and the 10 worst fillups averaged 21.2 mpg (urban). All of the above was on 91 octane or higher fuel. I'm pretty light-footed, but my wife (Lady Leadfoot) has been the major driver of this car.
