Why the discrepancy? Because the manual assumes you are using Toyota-approved oil. If you use cheap mineral oil, stick to 5,000 km. But if you buy the good stuff (API SN or ILSAC GF-5), trust the manual and save yourself two oil changes a year.
For Wigo 1.0 G and TRD variants (2020+):
“Use of lower-octane fuel (below 91 RON) will cause knocking, reduced power, and potential engine damage.”
