Cerma Dosage & Application Instructions

This guide provides complete dosage recommendations for Cerma STM-3 Engine Treatment and Cerma Blue Ice A/C and Refrigeration Treatment. Follow these instructions for optimal results.

Dosage - How Much Should I Use?

Newer vehicles require a smaller dosage. Please make note of how many miles are on your vehicle and adjust the dosage appropriately. After adding Cerma STM-3 Engine Treatment to the motor oil, autos should be driven for a minimum of 1500, trucks and semi trucks for a minimum of 3000, and motorcycles a minimum of 500 miles before changing out motor oil. This allows for the Cerma Engine Treatment to achieve its full cleaning capabilities.

Application Procedure

  1. Warm engine to normal operating temperature and add recommended dosage to ENGINE OIL. Add Cerma STM-3 Engine Treatment while the engine is running. DO NOT add to your fuel tank. If blow-by or pressurized oil system is present, shut off engine, add dosage amount, close cap and immediately restart engine. (More is Not Better - Use Only Recommended Dose)
  2. Keep engine running and immediately after treatment is added, bring engine up to 1500 to 2000 rpm and hold for 2 to 4 minutes. This will ensure that the Cerma STM-3 Engine Treatment circulates throughout the engine.
  3. Continue to run engine for no less than 30 minutes. The preferred method is to drive the vehicle for at least 20 - 30 miles (40 miles for trucks), the longer the better. As the oil is circulated, Cerma STM-3 treats the metal. As you drive, you may start to notice a decrease in noise and vibration – this is the Cerma doing its job!
  4. Do not change oil for at least 1500 miles (3000 miles for trucks and semi trucks, 500 miles for motorcycles) after adding Cerma STM-3 Engine Treatment to motor oil. Otherwise you may change your oil at the manufacturer's recommended interval.
