DEVELOPED THROUGH TESTING
Approximately 35% remains our standard treatment based on laboratory testing and accumulated field experience.
THE FORMULA
Replace approximately 35% of the engine’s specified motor-oil capacity with S2N-35. The remaining approximately 65% is the motor oil appropriate for the application.
WORKS WITH YOUR MOTOR OIL
S2N-35 works alongside the remaining motor oil rather than replacing the entire lubrication system.
TESTED BEYOND 35%
Different concentrations have been evaluated in field use. Approximately 35% remains the standard S2N-35 treatment while observations at other concentrations continue to be documented.
Using S2N-35
Find answers to common questions
S2N-35’s standard treatment replaces approximately 35% of the engine’s specified motor-oil capacity. The remaining approximately 65% is the motor oil appropriate for your engine. S2N-35 counts toward the total fill; do not add it on top of a full crankcase. Follow the product directions and your engine’s specified oil capacity.
No. S2N-35 replaces a portion of your motor oil and works alongside the remaining oil. At the standard treatment, approximately 35% of the total fill is S2N-35 and approximately 65% is the motor oil appropriate for your engine.
S2N-35 is designed for use alongside conventional, synthetic-blend, and full-synthetic motor oils. Use the motor oil specified for your engine and follow the S2N-35 product directions for the appropriate treatment.
No. S2N-35 replaces part of the motor oil; it does not increase the engine’s specified oil capacity. Include both S2N-35 and motor oil when calculating the total fill. Follow the product directions and check the oil level using your vehicle manufacturer’s procedure.
Approximately 35% remains the standard S2N-35 treatment based on laboratory testing and accumulated field experience. Other concentrations have been evaluated in field use, but those observations do not replace the standard treatment recommendation. Follow the product directions for your application.
