Sedans Lexus ES Lexus ES 350 Real World MPG

I just picked up my ES350 and drove from the west coast of FL to the east coast, using a combination of interstates and two-lane roads, with 10% city streets. It was common to be cruising at 70 - 80 MPH, always with the air on. The 191-mile trip back averaged 29.8 mpg using 91 octane. I plan to switch to 89, then 87, which is what I did on my '97 Avalon. That car also called for 91, but I have 148K miles on it with 87 octane and no problems. I don't anticipate a problem with 87 in the ES.

Replying to: rocketdan (Jul 06, 2006 10:35 am) I had always thought, perhaps incorrectly, that even if you could use the lower grade fuels you would burn more of it and hence need more frequent fuel stops. I guess this would mean lower mpg, etc. Is this faulty thinking? SammyS

...Just thought I'd give all you guys and gals a little update on what this incredible engine/transmission combo is capable of. I gassed up and immediately got on the highway and drove straight for about 45 miles at a fairly steady 65-70mph with the climate control shut down (it was 68°). When I got off the highway and rolled up to the first light the "tank ave." told me I had done 34.2mpg !!! About a mile later after a bit of stop and go traffic it was still reading 33.3! The way I figure it, this incredibly efficient power plant, with its VERY healthy 272hp on tap is giving me over 50% better gas mileage than I was getting from my '02 ES 300 (good for only about 23/16mpg in real life driving). I'm a bit surprised that the almost incomprehensible efficiancy of this engine doesn't get more press. It's really unbelievable. And, let me tell you, when you need the power and you put your foot into the accelerator, this thing is a rocket ship! Heck, the way I figure it I'm still "only" paying the equivalent of about $2.25/gallon. |

I drove 130 miles on freeway with cruise control on at 68-70 miles per hour with air conditioning on 20-30% of time. "tank ave" was reading 36.9mpg. I took the same road on the way back with air conditioning on 50% of time, "tank ave." 35.2mpg. I filled the tank with 91 octane before I started my trip. It is very impressive for 6 cylinder car. I drive mostly surface streets and during rush hours on freeway in so. calif. my ave. mpg hasn't been better than 22mpg. I have the car for 6 weeks and I am not sure it will hold the same mpg one-two years from now. Any way, I am still impressed with 36.9mpg.

| Right after getting my ES, I drove from the west coast of Fl to the east coast, about 190 miles. The MPG was 29.8 while going 75-80 MPH with the air on continuously. My next tank (89 oct.) is being burned off in rush hour traffic. We have had bad thunderstorms and lots of stop-and-go in commuting. I'm still geting 24.5 MPG. This compares to 22 MPG in the same traffic with my '97 Avalon 3.0 liter 192 Hp engine. I am very pleased. My next tank will be 87 octane, which I always used in the Avalon. | |

Just completed a 2845 mile trip to TN. 50% on interstates at 75-80 mph, about 25% on two lane country roads, up and down through hills, and about 25% town driving in moderate traffic. Computer indicated 28.9 mph but when caculated (after writing down gallons used each time) actual mileage was 28.71 mpg which I consider to be excellent.

I just completed a trip from NYC to Rochester NY. With 11 bowling balls in the trunk I got 26.9 mpg combined city/hwy. On the way back with just highway driving in the rain I got 32.9 mpg. It's amazing that the car only goes up to 2000 rpm at 70 miles per hour.

Replying to: oldman26 (Jul 24, 2006 5:01 am) I've found the trip meter takes at least 45 minutes of driving before it will settle down to give a consistent and accurate reading. BTW, these mileage figures are based on dividing the number of miles driven by the number of gallons used, not by relying on the car's mpg readings. In my ES350 the car mpg readings are usually within 1 mpg of what I calculate. |
