To use STP Diesel Oil Treatment, add the entire contents of the bottle to your engine oil when the engine is warm. One 300ml bottle treats 4.8 liters of oil (a 6.2% treat rate). Do not overfill your engine oil.
Here's a more detailed breakdown:
- Warm Up Your Engine: Run your diesel engine for a few minutes to warm the oil. This helps the treatment mix more effectively.
- Locate Oil Fill Cap: Find the oil fill cap on your engine. Consult your vehicle's owner's manual if you are unsure of its location.
- Add the Treatment: Carefully pour the entire bottle of STP Diesel Oil Treatment into the oil fill opening.
- Check Oil Level: After adding the treatment, check your engine oil level with the dipstick. Ensure that the oil level is not above the "full" mark. Overfilling can damage your engine.
- Replace Oil Fill Cap: Securely replace the oil fill cap.
Important Considerations:
- Dosage: Stick to the recommended dosage of one 300ml bottle for 4.8 liters of oil.
- Frequency: Refer to the STP Diesel Oil Treatment product label for recommended usage frequency (e.g., with every oil change).
- Compatibility: Although formulated for diesel engines, double-check the product label to ensure it is compatible with your specific vehicle and engine type, especially if you use synthetic oils.
- Purpose: Understand that oil treatments are intended to supplement, not replace, regular oil changes.
By following these steps, you can properly use STP Diesel Oil Treatment to potentially improve your engine's performance and longevity.
