Ravenol TSi SAE 10W-40 Semi-Synthetic Engine Oil (5 Litres)
Provide your vehicle's engine with superior, year-round protection and efficiency using Ravenol TSi SAE 10W-40 in a convenient 5-litre container. Built with advanced CleanSynto® technology, this premium semi-synthetic engine oil blends high-grade hydro-crack base oils and polyalphaolefin (PAO) synthetic components to offer reduced friction, minimal fuel consumption, and outstanding low-viscosity performance.
Engineered to meet the rigorous demands of modern petrol and diesel passenger cars and light commercial vehicles—including turbocharged, multi-valve, direct-injection, and catalyst-equipped engines—this oil delivers dependable, long-lasting performance.
Key Features:
- CleanSynto® Technology: Advanced formula that actively reduces friction and fuel consumption while keeping internal engine components remarkably clean.
- Exceptional Cold-Start Behavior: Excellent flow characteristics ensure rapid oil distribution across critical engine parts during low-temperature startups, reducing initial wear.
- Sludge & Deposit Prevention: Outstanding detergent and dispersant properties actively stop the buildup of black sludge and oil coking.
- High Thermal Stability: Maintains a stable, consistent viscosity profile across demanding driving conditions and extreme operating temperatures.
- Low Evaporation Loss: Minimizes oil consumption so you spend less time topping up between services.
- Ideal Service Size: The 5-litre volume is perfectly proportioned for standard oil and filter changes on a wide variety of passenger and light commercial vehicles.
