WOW....I get about 19/ 20mpg average on 87 oct. I'm not kidding, if I got less I'd be pissy.

okay,yes you can find out via the vin# what service was done @ Lexus.I have a 2001,so my fuel tank is bigger than the 99,I can tell you that I get around 18-18.2 in the winter time,And 19-19.8 during the summer time.I have also discovered that the fuel mileage computer is fairly accurate.I get around 1.5 mpg more that it reads out.(witch is better than less).I do wish we had the miles to empty option.I`m sure you will find your RX a very dependable,nice driving,well built/engineered,machine.(BTW) if you haven`t already,switch to synthetic in everything! You will be glad you did.

Thanks. Right now the RX has new fluids on the rear and front gear. Engine oil is nice and clean when I bought it so I'm not wasting it for another 1k miles or so. Need to change trans oil for a piece of mind, even though it is cherry red. If I keep the RX and get it to go 100k miles then I'll switch everything over to Syn.

OK, for the mpg's.

If you reset the MPG's and average MPH clocks at fill up, WHAT is everyone's average on both when it's time to fill up again?

I'm averaging 12.9 MPG at 14.8 MPH on my second fuel tankfull since I bought the RX. My first tankfull got me a whole 221 miles.

The 99's have a smaller tank but what is the 99 getting on a tankfull on mostly city driving?

^^ This is exactly what my brother is getting in his 99 Awd. He is pure city of Chicago driving.

I'm getting around 19.5-20.1 with and avg. of 25mph on my 2000 Awd.
At first I was getting 17.2 until I found out I had a dragging RF caliper.

I too would also want to know what others are avg. on mph to their mpg.

What is a dragging RF caliper? I'm getting only about 13MPG with city driving here in San Francisco, and my area doesn't necessarily have that many inclines.

I have a 2000 AWD, average is around 22mpg combine both highway and interstate.

The average was at 20mpg, as high gas price recently, I start using cruise control while on highway. Sometime I even turn on cruse control while driving locally. You will be surprised what you going to get when the speed is at 25-30mpg and 40-45mpg. I got 25-26mpg believe it or not. Therefore, if you want to save your money, use your cruise control as much as you could. That is 10% of gas saving.

That's a good point. On my trip home from Mexico to Florida, I average well over 25 mpg, with my RX fully weighed down, and used cruise control on the highway.

just bought my 99 RX300 less than one month ago. really love it.

ONE QUESTION: how do you get accurate mpg number for highway driving or city driving? The MPG # I can get is by reading the number on screen. It was 19.6mpg when I just bought it. Now it steadily increases to 21.3mpg. it was a mixed number for highway and city driving. guess I have a good driving style?

I am using 89 octane. Previous owner told me that he always use 89 octane.

It is actually liquid wrench, but carb cleaner works well, too.

jimmouse · 06-24-08, 09:42 AM

It depends a lot on what RPM at local and a lot of wind resistance on the high way also. After changing my belts, I did get higher milage, 17+ for the 10 mitutes drive to work averaging ~28mph.

I'd really stick to the Densos. It's one of those few things that I like to stick to stock. The only other thing I'd run would be wideband sensors, but that's only if you want to do some performance tuning...I might do that in the future.
