Can I switch to synthetic after my first 8000km oil change?? - Toyota Yaris Forums

If you're not sure, I'd just go with the manufacturer's recommendation, which is 8000km for the first oil change and anything goes afterward.

From personal experience from my last two cars, I've found that the engine start to get quick at around 30,000km on regular oil. Given that synthetic is suppose to be significantly better at lubricating, I wonder if the same effect could be achieved from a car that's been fed synthetic from an early age.

It's also interesting that of all the car I've encountered that have over 400,000km on it, none of them were running synthetic. Has anyone heard of a synthetic user pushing that kind of mileage?
