#19 of 28 type of gas by blk99ls Jul 05, 2006 (6:30 pm)
Is it true that you can only use 93 octane in the 99 LS? How about 91? Replies to this message: nvbanker (Jul 09, 2006 11:08 am) pat (Jul 09, 2006 12:16 pm) pearl (Jul 10, 2006 3:22 pm)

Replying to: blk99ls (Jul 05, 2006 6:30 pm) Can't be. Most places you can't get 93..... Replies to this message: pat (Jul 09, 2006 12:16 pm) pearl (Jul 10, 2006 3:22 pm)

Replying to: nvbanker (Jul 09, 2006 11:08 am) Hmm ... here in SE Va you can't get 91, you can only get 93 if you want something higher than regular octane. I was under the impression that was true in most parts of the country.

Replying to: nvbanker (Jul 09, 2006 11:08 am) where do you live? I think octane is also frequently a factor in the altitude of the location. When I lived near Denver, 91 was all you could get. Now I live in Maryland and here, as well as most of the (low altitude) east coast, the octane is 93 at pretty much all stations/brands. I also used to note 91 octane in WY and UT - again mostly high altitude locations.

I'm in Las Vegas. 91 & 100 is all you can get here. We're at 2000 ft. though. Coastal areas probably get 93. In Utah and the rockies, you can actually get 85, whereas 87 is the lowest we can buy.

My wife drives her 2006 LS430 about 99.5 % , the rest of the time I drive it, to put gas in it. This past time , while distracted by this beautiful , young , attractively dress blond , I push the Regular gas , and so far my wife has not notice the difference but for me , I want to gas up everyday at the same time. This was an accident ( the Gas ) , the next time back to High Octane, just the car.

Around town, you probably won't, (and your wife for sure won't) notice a difference. On the highway, hills and passing, I notice a fair difference.....

Replying to: sbadeaux (Jan 09, 2006 4:29 pm) The fleet reference was incidental to the topic of the proper fuel to use. However, as a matter of information I have rented a Lexus ES from Thrifty Car Rental in Los Angeles as well as an LS from Midway Car Rental. They may no longer offer rentals, I don't know. But - if you cannot buy a Lexus from a fleet, rental or otherwise, how does the rental company eventually dispose of the vehicle?

#28 of 28 Very happy with MPG on 2002 LS430 by 2002ls430girl Aug 06, 2008 (6:22 am)
Very happy with MPG on 2002 LS430   Just got back two days ago from a road trip. The car was loaded with 4 adults (3 who drove) and a trunk full of luggage. I calculated the mileage on paper instead of the computer as I didn't want to zero everything out. 1780.3 miles 68.95 Gals at a total cost of $281 - 25.8 MPG. We paid between $3.919 and 4.219 for high test. Also this raised my average MPG two tenths on the 'puter. It now sits at 22.4 MPG.   The car has low mileage, about 80,000 miles. I have to say I am very pleased with the MPG. It easily holds four people and a hugh pile of stuff. Fully loaded it's a quiet, smooth, very comfortable ride and the mileage is wonderful for what we have.   I was toying with buying something new next year, but for the value I am re-thinking. I may just keep my trouble free car.
