Ravenol TSi SAE 10W-40 Semi Synthetic
Optimize your engine's efficiency, cleanliness, and protection with Ravenol TSi SAE 10W-40. Formulated using advanced CleanSynto® technology, this high-performance semi-synthetic engine oil combines premium hydro-crack base oils and polyalphaolefin (PAO) synthetic components to deliver exceptional low-viscosity performance and minimal evaporation loss.
Engineered for year-round operation, Ravenol TSi is ideal for modern petrol and diesel engines—supporting both turbocharged and naturally aspirated variants, multi-valve setups, direct-injection systems, and catalyst-equipped vehicles.
Key Features:
- CleanSynto® Technology: Advanced additive and base oil combination that promotes fuel-saving operation and active engine cleanliness.
- Superior Sludge & Deposit Control: Outstanding detergent and dispersant characteristics prevent the formation of black sludge, keeping oil-ways clear.
- Exceptional Cold-Start Performance: Excellent flow characteristics ensure rapid oil distribution and immediate wear protection during cold morning ignitions.
- High Thermal & Oxidation Stability: Maintains a consistent, stable viscosity across wide temperature ranges for long service endurance.
- Robust Wear Protection: High abrasion resistance ensures vital internal components are shielded under varying driving loads.
- Convenient 1-Litre Size: Perfect for routine fluid top-ups, keeping in the boot for journeys, or completing smaller capacity changes.
