Muller Industries USA Prius update! Drained the motor oil .. black and gritty. We did an oil flush, fresh 5w30 High Mileage (3.75 quarts) and new oil filter. Even if you don’t own a hybrid, change your oil! Better gas mileage counts a bit towards clean air. What’s next? #proudpriusowner #recycle #cleanair #mpg2019 #staygreen https://www.instagram.com/p/B5RLtg0HQrT/?igshid=i3cv01ry8bud
