well considering its a gs400 4.0 liter engine..

about 5.5 quarts...so get 6 quarts because some oil filters are a bit larger than others.

You can recieve a free owners manual here https://www.clublexus.com/forums/great-deals/92845-free-lexus-owner-s-manual-if-you-lost-yours-interesting.html

Or you can 1800-GO LEXUS to request one. If this does not work out, pm me and I will ship a spare manual to you..

As far as the oil goes, Our cars require 5w30 motor oil. You can use 10w40 as well during extreme hot summers. Synthetic or dino oil is your call... I've been using synthetic myself for years..
Good luck..

Thanks just ordered my owner's manual. Manual was missing when I bought the car a month ago.

why would you bump a thread about an oil change if you wanted to talk about owners manual...

You need 5.7 qts of any viscosity oil you choose. If you were prev on full sun stick with if not use conventional
