I've tested the mileage on probably 20 or 25 tanks of fuel in my GX, some tanks regular and some premium. I did the testing the old-fashion way (miles divided by gallons to fill the tank) and compared the results to the on-board mileage computer. The on-board mileage computer is pretty optimistic, showing about 1.5 -1.7 MPG higher than actual if I recall correctly (it's been a few years since I did this, but I'm pretty sure that was the range of error). So I don't pay attention to the on-board mileage computer, or I deduct about 1.6 MPG. from whatever it says. Anyway, using the miles-divided-by-gallons method I routinely got about 15-16 MPG in mixed in-town and highway driving. At about 55 MPH steady-state driving it WILL get 21 - 22 MPG, but the problem is that one can only rarely drive this way for very long. So, in real world, my experience is that mileage is going to be more in the 14 - 17 range, depending upon where and how I'm driving.

[QUOTE=deeken;10098490]How do u possibly get 20mpg when 18 is the factory maximum mpg?
Sorry, should have clarified. Average mpg is closer to 17. It does get into the 20’s on flat ground with no crosswind. I keep my engine top end and fuel system clean, and having a clean air filter doesnt hurt. The truck sees regular fuel. Premium only in my LS430

I had my 05 GX470 since 2005 when it was new. Love that car. For the past 12+ years, I changed oil and filter regularly every 5000-8000 miles. Engine stills run fine but I got the impression that it is not as punchy as when it was a few years back. Timing belt and water pump were changed at 90K miles. Experienced leak at the edge of the radiator at 120K miles (apparently common) and radiator was replaced. All fluids (power steering, front differential, rear differential, transfer case) were replaced at 80K miles and at 160K miles. Front CVs and rear shocks were replaced at 130K miles.
The vehicle now has 175K miles and probably ready for another timing belt and water pump change. I am debating if I should keep the vehicle much longer. If so, how many extra miles will I get out the vehicle if I continue to do regular oil/filter change?

It will last as long as you want to keep it. Unlike cars designed and built in the 80’s modern cars will go quite a bit further. Being a Lexus they designed these vehicles for longevity. They might not get the best fuel mileage but what they lack in that regard they make up for in reliability/dependability. The only factor you should be concerned with is the maintenance cost versus the price of a new vehicle. If you spend a couple hundred dollars a year to keep it on the road it’s going to be much cheaper than thousands down on a new vehicle. I’m willing to bet that your maintenance cost would be a fraction of the depreciation amount of a new vehicle. Also with a new vehicle you will still have maintenance costs; tires, brakes fluid changes & a substantial increase yearly in registration fees and sales taxes when you purchase the vehicle.
Just keep up on regular routine maintenance and you should get another 175K out of it. If you still like driving the vehicle why stop? You know the history and it’s been well taken care of.

Two upstream, two downstream I believe. Yes it can be a DIY job, but they probably will not come out easily. You can rent a tool from a autozone or where ever. I would soak multiple times with Penetrating oil over a day and work on it the next.
yes, these sensors can/will effect performance.
