I know very little about car mechanics, but ChatGPT says this is the best oil for my car, and the unit price on this one is better than on the 5L Castrol EDGE 5W-30 currently on sale at Autobarn.
Penrite Enviro+ GF-S Engine Oil 5W-30 7L $49.99 (Was $99.99) + Delivery ($0 C&C/ In-Store) @ Supercheap Auto

I'd rather rely on Penrite's Product Selector than a third party robot.

Better yet, read your the manual that came with the car.
FWIW - the Penrite selector says this one "not compatible", showing 10W-40/50 for mine. The manual gives me 5W-30 (which I use), 10W-40, 15W-40 and 20W-50.
Edit - here's what ChatGPT gave me:
If you live in an extremely hot or cold climate, the viscosity may vary slightly (for example, 0W-30 in very cold areas), but 5W-30 synthetic works well in almost all conditions and is what Lexus recommends.
Cool. My car takes 6.6 so I usually buy a bunch of the same brand when on special and just used the last of the Nulon. I miss my 4cyl that only needed 5lts
Bought it for my mazda 3, good deal. Oil change every 5k not 10k like mazda say.

Trust your owner's manual from manufacturer of engine or car. NOT CHAT GPT
Can recommend this oil for T32 xtrail, i put it in 2 weeks ago and the car is still running! But just FYI car takes just under 5L so 7L is more then 1 oil change but not enough for 2.
Oh V8s take 7L.
