||Serious racers want to reduce friction as much as possible to help get maximum performance. That's why Q-Racing developed a line of engine oils formulated specifically for extreme racing conditions. Quaker State offers customized oils to help maximize the power and performance of precision-tuned racing engines. All Q-Racing Oils are full synthetic, PAO based, engine oils formulated to reduce friction across the entire range of racing engine temperatures. Less friction typically means more horsepower and less wear. By creating purpose-built lubricants for racing, we don't have to limit our formulations to meet industry mandated street oil specifications. Zinc-type additives provide outstanding engine wear protection, and you will find the levels in Q-Racing Oils are significantly higher than street oils. We also utilize friction modifiers and anti-foaming additives that meet the demands of extreme racing conditions. Anyone can put ''racing oil'' on their label, but it's what's inside that makes the difference. With Q-Racing Oils, engines receive high-heat protection for outstanding performance from start to finish.
