Greetings from England!
I bought a 2000 Yaris with 163k miles exactly one year ago this week. It has service history from Toyota and other local garages. I changed the oil using semi synthetic 5w30 last year and 5,000 miles/1 year later I think I should've used a 10w30 being that it is a high mileage engine and given the climate in the UK. I don't think it "burns" much oil because there is no smoke from the exhaust and it passed UK emissions testing however I check my oil very often and usually top up just a little bit each time to keep it close to the max mark.
I have always used the whatever viscosity the manufacturer suggests and bought whatever brand semi synthetic oil in the past but I'm interested to know what you think is suitable?
Edit:
Some more detail:
I drive the car quite hard sometimes but I usually let it warm up before driving. It has a stainless performance exhaust. No known problems. The handbook suggests 5W30 in cold climates but also says "preferred" next to it. In climates above -18C it suggests 10W30. It also states "use API grade SJ, Energy Conserving or ILSAC multigrade engine oil. I do a mixture of highway and city driving.
