We formulate VP Professional Grade SAE 0W-20 Full Synthetic Racing Oil to deliver superior durability and friction control. Its leading-edge chemistry provides both maximum power and protection. Whether youre a pro, semi-pro, or a high-intensity amateur racer, Pro-Grade 0W-20 oil helps you perform and succeed. However, it is not compatible with top-fuel/nitro drag racing or catalytic converters, which are found on most street cars. Furthermore, DO NOT mix oil additive supplements with any VP Professional Grade Full Synthetic Racing Oils. Another key point is that we also blend VP ProGrade Full Synthetic 0W-20 Racing Oil with an aggressive dispersant detergent package. This helps control both deposits as well as the oxidation stability of the oil. Therefore, it takes much longer for the oil to oxidize than other brands on the market.
