When should I start using synthetic oil?? - Page 4 - Toyota Yaris Forums

The dealer fielded this question today in my conversation with them, I started at 36K, they said you can start it as soon as you wish, They said the real concern is when someone has an older engine that has only seen conventional an then its not recommended to switch. so the sooner the better but probably before 36K is recommended.

I think it's a spurious concern to worry about mobilizing sludge by using a new type of oil. (That's been around since the first detergent oils came on the market.) Change it more frequently the first time or two if you're worried about it. (But I plan to stick to the conventional stuff on the normal recommended change schedule anyway.)
