Valvoline Engine Oil Treatment – Performance Booster for All Engines
Purpose and Specifications
Valvoline Engine Oil Treatment (300 ml) is a specialized additive package designed to enhance the performance of your existing engine oil. This product works with all petrol and diesel engines, making it a universal solution for engine maintenance.
What It Does:
- Thickens oil at high temperatures to maintain a stronger protective film around engine parts
- Reduces oil consumption by sealing gaps between piston rings and cylinder walls, especially in high-mileage engines
- Prevents oil leaks from worn seals
- Protects against oxidation and deposits that build up over time
- Improves engine performance in extreme cold winters and hot summers
How Much to Use:
One 300 ml bottle treats approximately 4.5 liters of engine oil. Simply add the entire contents to your oil and run the engine at operating temperature. Safe to use up to 20% concentration of your total oil volume.
When to Use / Replace?
Add this treatment during regular oil changes or when you notice:
- Increased oil consumption between service intervals
- Oil leaks from seals or gaskets
- Extreme temperature driving conditions (very cold or very hot climates)
- High-mileage engines (typically 100,000+ km) showing wider tolerances between moving parts
The treatment supports extended oil drain intervals, helping you reduce maintenance costs and friction-related wear.
Important: Do not exceed your engine's maximum crankcase capacity when adding this product. Not recommended for vehicles still under manufacturer warranty.
Frequently Asked Questions
Q: Will this damage my engine?
A: No. Valvoline Engine Oil Treatment is harmless to all engine types when used at the recommended concentration (up to 20% of total oil volume).
Q: Can I use this in both petrol and diesel engines?
A: Yes. This additive is suitable for all petrol and diesel engines, making it a versatile choice for multi-vehicle households.
Q: How often should I add this treatment?
A: Add it during each oil change, or as needed when you notice increased oil consumption or leaking seals. One bottle per oil change cycle is the standard approach.
