How to Add STP Oil?

To properly add STP oil treatment, you should pour the entire contents of the STP product into your engine's oil when the engine is warm.

Step-by-Step Guide: Adding STP Oil Treatment

Here's a detailed guide on how to add STP oil treatment, based on the provided usage directions:

1. Warm Up Your Engine: Before adding STP oil treatment, run your car's engine to ensure it is warm. This helps the STP product mix properly with the engine oil.

2. Determine the Correct Amount of STP:

   • For engines with approximately 3 litres of oil, use one 300ml can of STP.
   • For engines with 4 to 5 litres of oil, use one 450ml bottle of STP.
   • This ensures a treat rate of approximately 10%.

3. Pour in the STP Treatment: Add the entire contents of the can or bottle of STP directly into the engine's oil fill opening.

4. Check Oil Level: After adding the STP product, check your engine's oil level using the dipstick to ensure it's within the recommended range.

5. When to Add: STP oil treatment should be added at the time of an oil change or in between oil changes, to gain the benefits.

Key Points to Remember:

• Warm Engine: Always add STP to a warm engine.
• Correct Ratio: Use the proper STP product size based on your engine's oil capacity. (300ml for 3L and 450ml for 4-5L).
• Treat Rate: STP should be added at a 10% treat rate.
