Before adding this oil, verify your vehicle owner's manual to confirm that a 5W-30 viscosity is recommended. Drain the old engine oil completely from the sump while the engine is warm but not hot to ensure contaminants are removed. Replace your oil filter at every oil change interval to ensure the synthetic additives in the R-Tec 21 can perform effectively.

Do not mix with lower-grade non-synthetic oils, as this can degrade the specific performance benefits of the R-Tec 21 formulation.
