Royal Purple 55484 SAE 0W-40 High Performance Synthetic Motor Oil European Formula 55-Gallon Drum

Royal Purple 55484 is a premium full-synthetic SAE 0W-40 motor oil engineered specifically for European passenger car and light-duty diesel engines. Formulated exclusively with high-quality synthetic base stocks and advanced additive technology, it delivers robust engine protection and sustained peak performance — packaged in a convenient 55-gallon drum for high-volume commercial and fleet applications.

Designed to meet the demanding lubrication requirements of turbocharged gasoline, direct-injection, and diesel particulate filter (DPF)-equipped engines, this European-formula oil delivers consistent protection across a wide range of operating conditions.

Key Features & Benefits:

• Exceeds API SP and ACEA A3/B4-21: Wear protection engineered to surpass the requirements of current API and ACEA specifications
• Outstanding Low-Temperature Performance: Cold crank viscosity of 5,997 cP @ -35°C ensures reliable cold-start lubrication and immediate oil flow
• High-Temperature Stability: Flash point of 232°C (450°F) and HTHS viscosity of 3.6 cP @ 150°C provide a robust lubricant film under extreme heat
• Excellent Oxidation Stability: Low volatility properties reduce oil consumption and extend service intervals consistent with most European OEM recommendations
• Superior Sludge & Varnish Resistance: Advanced additive chemistry prevents harmful deposits during stop-and-go driving and other severe operating cycles
• Corrosion Protection: No rust observed in standard industry corrosion testing
• Optimized Fuel Efficiency: Low coefficient of friction reduces internal engine drag for improved fuel economy
• High TBN: Total Base Number of 12.3 mg KOH/g provides strong acid neutralization for long-lasting engine cleanliness
