Those of you who have recently purchased a new RX350 and plan on using the dealers "free oil/filter change coupons" that may have come with your purchase need to be aware of something.
I'm an '06 Avalon owner and am posting this here because our vehicle's share the same motor - both are made by Toyota.
The coupons read "up to 5 qts." - unfortunately your car holds 6.4 qts. of oil; not 5 qts.
I've searched the WEB and have learned that many Toyota dealers are only installing 5 qts. in the '06 Avalon motor. I'd bet a buck the Lexus dealers are doing the same thing. I've been on this earth a few yrs. and have learned that there's liitle difference in car dealerships, be they Luxury or not.
All the more reason to change your own oil. Here's the URL with the instructions:
