Valvoline Inc. announced the retail launch of its newest gear-oil packaging innovation, FlexFillTM. The patented FlexFill bag will make changing synthetic gear oil easier — all while providing a more flexible, less wasteful automotive Do-It-Yourself (DIY) experience. Historically, synthetic gear-oil packaging has consisted of hard plastic that is difficult to maneuver in an automobile's undercarriage — resulting in unused product per bottle. FlexFill's innovative packaging will allow for less waste, all while providing an easier user experience, even in compact spaces. FlexFill packaging is available in two synthetic gear oil grades — SAE 75W-90 and SAE 75W-140—and can be purchased at various retail outlets nationwide, including Advance (April 2021), AutoZone Meijer and Walmart, as well as on Amazon.
