I have a Aqua(Prius c) and I do regular engine oil changes in every ~5000km. My question is when to change ATF oil in Prius c? and is there any thing such as ATF in prius c?. How do I know my oil is bad.? Mine millage says 25000km. Thanks
yes, there is atf. there's no toyota recommendation in the u.s., but many here recommend every 30,000 miles. it's really your decision on preventative maintenance outside the parameters of the manual.
