Here is a good deal if you like to do your own oil changes. Genuine Toyota/Lexus Oil and Air Filters for our LX570s.
This is the best deal i could find and you know they are NOT counterfeit since it is from a Toyota Dealer.
Free shipping if you spend over $75.

This will work great for me since i like to change the engine oil every 5k miles.
I can change the oil and filter for about $20.
you can find great deals on oil at slickdeals.com
Slickdeals currently shows a $25 rebate deal on two 5qt jugs of Pennzoil full synthetic. Walmart and Amazon are selling a 5qt jug for $23.78..

 

I should be set for the next few years.
