OILSTAR ELITE SERIES – SAE 10W-40 Performance Street Engine Oil - 5 Litre
Premium Protection for Serious Drivers
Oilstar Elite Series SAE 10W-40 is a high-grade synthetic engine oil engineered specifically for enthusiasts who demand superior protection and performance from their vehicles. Designed to handle the extreme demands of modified engines, classic muscle cars, weekend track warriors, and everything in between, Elite Series delivers professional-level protection for any petrol or diesel engine on Australian roads.
From factory-fresh daily drivers to heavily modified performance machines, Elite Series provides exceptional defence against wear, heat, and deposits. This advanced formulation features an elevated concentration of zinc and phosphorus-based anti-wear compounds, making it the ideal choice for engines with aggressive valve train configurations, forced induction systems, or high-revving naturally aspirated setups that push conventional oils beyond their limits.
Advanced Additive Technology
At the heart of Elite Series is Oilstar's exclusive ProShield additive package—a scientifically developed chemistry that dramatically strengthens the oil's protective film barrier between metal surfaces. This technology minimises direct metal-to-metal contact, substantially reducing friction and wear throughout the engine. ProShield also delivers outstanding resistance to heat-induced breakdown, maintaining superior lubrication even under extreme operating temperatures whilst preventing harmful deposits and extending service intervals.
The synthetic base oil blend combined with ProShield technology provides exceptional oxidation resistance and natural cleaning properties, keeping internal engine components remarkably clean throughout the oil's service life.
Elite Series outperforms conventional and competing synthetic oils in both petrol and diesel applications, including turbocharged and supercharged engines. This premium formulation is specifically developed for vehicles outside manufacturer warranty periods or for drivers seeking maximum engine protection without the chemistry limitations found in mainstream oils. Meets ACEA E9-16 performance standards.
KEY PERFORMANCE BENEFITS
Ultimate Wear Defence – Provides industry-leading protection against engine wear, exceeding the capabilities of standard street oils
Enhanced Power Output – Superior lubricity and reduced friction coefficient, combined with improved piston ring sealing, translates to measurable gains at the wheels
Extended Service Life – Exceptional resistance to oxidation allows for longer intervals between oil changes without compromising protection
Extreme Temperature Capability – Synthetic base stocks and ProShield technology maintain integrity under severe thermal stress
Superior Engine Cleanliness – Advanced synthetic dispersants prevent deposit formation and maintain pristine internal surfaces
Modern Engine Compatibility – Specifically formulated to minimise Low Speed Pre-Ignition (LSPI) in turbocharged direct injection petrol engines
APPLICATION
Suitable for all automotive petrol and diesel engines. The perfect choice for performance vehicles, modified engines, dual-purpose street/competition cars, and stock vehicles requiring maximum protection. Available in 5 litre containers.
