You are in the Lexus RX 400h Forum. Your Host is pf_flyer
I am really attached to the 400h. I asked for a vanity plate for my birthday. It came in two days ago. KIKNGAS  Purchasing a hybrid was also a statement. I felt if one life could be changed or a step toward energy change be met, I might be a small part......I don't feel I gave up a thing. My "fun tickets" are well worth the experience with this car.

Rx400h is more or less my wife's car, but she is out of town so i have driven for last days. In last 275 miles, i am getting 31.3mpg. This is mix of highway/city/country, fast/slow, traffic/free flow. Key appears to be keeping down G-forces when accelerating, but dont have to go slow. I was doing plenty of 70mph. Wife, who likes to feel G-forces, tends to get 26-27. |

Replying to: apg97 (Jul 30, 2007 5:21 pm) I have never gotten much better than that. Most of my driving is in the city, on relatively short trips around town, especially during the summer when I'm not taking certain trips I normally take on the freeway. I believe my best sustained mileage was around 25.5. I guess you could say I'm not happy, at least with that aspect. I had an RX300 and I believe that car got close to 18-19 overall. It didn't have the power, but it rode better, was much better in terms of driver vision, and the Levinson sound system sounded better to my ears than the new one. Lexus didn't recommend premium fuel, either. I drove my RX400h for a while on regular and it runs fine, but to me it runs a little better on the 91 octane. But it's hard not to like the vehicle, overall. I must say, I don't have a fetish about getting extremely high mileage, and wouldn't drive differently just to get better mileage. If I need to accelerate, I do. But I don't have a leadfoot, and don't see why my mileage would be much different than anybody's. Out in traffic there are always situations in which stepping on it might help, as for instance at a light in order to get past a slower vehicle, and change lanes. If I need it to go, I do step on it. If I'm in a hurry, or want to make a light, or whatever, I do give it the gas. My guess is that I drive pretty much like most people, at least most who don't have a hybrid. I'm 55 and haven't gotten a ticket in about 15 years. |

Replying to: richcbt (Aug 18, 2007 12:07 am) I wanted a hybrid vehicle for some time, but I am a little concerned over getting the best mileage... Any tips? If the mileage is not working out well, can Lexus do anything? Like check the batteries, etc.?  Thanks!

Replying to: richcbt (Aug 18, 2007 12:07 am) On these vehicles, as with non-hybrids rated for 87 octane, there is no mileage or performance benefits to running high octane gas. You simply pay $.20 extra with no benefit. The engine is designed with a low enough compression ratio for low octane. High octane gas resists self-detination at higher pressures, but unless your engine is designed to take advantage of this, there can be no benefit. Note that on modern vehicles where premium (high octane) is recommended, you can run low octane without damage to the engine. The vehicle will compensate for the low octane by tweaking the timing, ignition, etc. (Note: older vehicles do not account for this and detination, and engine damage, can occur). When running low octane in modern premium-recommended vehicles, an associated decrease in performance and mileage will occur. But for an engine desinged for low octane, no performance or mileage increase can be realized by running premium. On a related note, for an accurate 'operating cost' and mileage comparison, a person should consider the manufactures recommended octane when choosing a vehicle. For example, if a vehicle, where premium is recommended, gets 20mpg and another vehicle gets 20mpg with regular octane, and there is a $.20/gal price difference, over 20,000 miles, 1,000 gallons of gas is used. For that 1,000 gallons, a $.20/gal difference amounts to $200 extra for fuel costs from two vehicles that get the exact same mileage. (Your savings may vary if your area does not have a $.20/gal priced difference between Premium and regular). So, not only does the RX hybrid get much better mileage, but it does so on $.20/gal cheaper regular gas rather than using premium gas like the RX330 non-hybrid.
