On a truly flat or slight downhill, right after an oil change, I might see 22 or 23 on the instant avg. But, over time always comes back to 17 to 18 in normal highway driving.

Very true. I get about 18 hwy and 14 city. I tend to drive 75 to 80 highway. Survey from From Club Lexus GX460 owners

2 short interval changes (1 free at dealer - 10k service), but did not do UOAs as I wanted to wait a bit longer for numbers to come down. I am not putting much mileage on my vehicles, and a lot of short trips. With break in wear numbers looking good, I will try to extend to 5000 to 7500 miles...

I have the yokohama geolandar g015 on my 19 gx460, a mild all terrain with 3 peak mountain snowflake. But, you can not go wrong with a good Michelin. The tires performed well in winter/mountain driving. https://www.yokohamatire.com/tires/geolandar-a-t-g015

I may change it again at 30k, b/c transfer case will be due at that time. But, that could be a couple years from now, as I am not putting much mileage on either of my vehicles.

Why yes, I did.

Drained the front and rear differentials on the GX460 and ran UOA on rear diff only. Toyota/lexus Factory fill 75w85 with 15,833 miles on the GX460 and diff. Good mix of highway and city driving, with car top carrier use. Refilled with Motul Gear 300.

Second oil change on the GX460 (just sent in sample from 11/2020. I believe I used 5w20 per my notes, but UOA states 0w20. Also had added 1 bottle of Ceratec which increased moly and boron on this UOA. The GX is almost at 16,500 miles now and will be sending in another UOA sample in January...
