The 2019 INFINITI QX60 3.5 liter V6 engine is equipped with 5 1/8 US quarts of 0W-20 motor oil. Oil and filter changes should be scheduled every 7,500-10,000 miles or 12 months if using fully synthetic lubricants, or every 3,000-5,000 miles or 6 months, if using conventional oil. The advantages of using synthetic vs conventional products include better lubrication among moving parts, a longer interval between service appointments and enhanced effectiveness under adverse weather conditions. An oil with a thinner viscosity like 0W-20 moves more easily in colder temperatures, coating engine components efficiently and providing better protection against friction and corrosion. Cost for a lube and filter job for the QX60 ranges between $150-$165 in parts and labor.
