I'm a bit more cautious on this Mazda engine, that while reliable, does have a tendency to mix combustion gasoline into the oil. My dip stick readings continue to rise over the miles until the oil level is over the fill line. Our family has two Yaris, and they both do the gasoline oil dilution, therefore- I have the oil changed every THREE thousand miles out of 'necessity'. I had the oil sent in for analysis on both cars, and it did indeed come back with over 2% gasoline and a low flashpoint. Since we want these cars to last, I'm opting to replace the oil more often.
Our models are the 2019 Yaris sedan and the 2020 Hatch.
