Gen 2 (2006) motor oil?

You can get electronic versions of (the usa version of) owners manuals and maintenance guides free from Toyota. There may be another site with eu-specific stuff.

tl;dr: any API "SN" rated 5W-30 motor oil will be fine. It's a relatively low performance engine that (thankfully) doesn't need anything weird or expensive- every grocery store carries it though you'll get the best deals at a bigbox store.

 

5W30 covers almost all conditions of this engine except extreme cold like -20 or better so if you're not in those extreme conditions you're probably not going to be doing anything but running 5W-30 pick your poison Dino oil synthetic send me synthetic blends doesn't really matter The one NZ engine is very forgiving The oil choice is going to be probably one of the least of your problems maybe keep it clean and changed this engine is very rarely drama-prone at all unlike the ZZ or ZR engine is the people like to call it in the Prius 3 same engine in a Corolla is no problem but in the Prius with Atkinson duty cycle and all of that sort of thing it just doesn't seem to be a real thing kind of a shame.

 

I would go with 5W30 Synthetic changed every 5k miles

 

In Europe, the change interval is 15,000 km or 1 year. They use a better oil filter to go with the interval.

 

The Toyota part number is 90915-10003 so get that from the dealer or an equivalent (but make sure it is equivalent) from an auto parts store.

 

That is a paper filter like they use in the US. I wouldn't use it if you intend on 15,000 km/12-Months interval.

Have you enquired at your local Toyota dealer to see how much the Toyota one is?

 

It looks like that part has been superseded by part no 90915-10009. They should be SEK103.05 each.

 

My receipts for dealership supplied oil filter say 90915-YZZN1. I've got a Gen 3, but have done the conversion to spin-on. I believe that's the same filter used on Gen 2, and later year Gen 4.

It might be good to get under there in advance, see what it looks like, and get the lay of the land. Will you be using ramps or floor jack with safety stands. If the latter you might want to look at the oil change link in my signature (on a phone turn it landscape to see signatures). It's Gen 3 specific, but not that different. The safety stand placement location I'm advocating are not at the scissor jack location, where originally described here by Hobbit, a Gen 2 owner.
