Why Choose Castrol Classic XL?
- Tailored Viscosity: Engineered to maintain oil pressure in older engines with larger internal clearances, preventing the "thinning out" issues of modern lubricants.
- Low Detergent Formula: Specifically designed to avoid the aggressive cleaning of modern oils, which can dislodge old deposits and lead to blocked oil galleries or seal leaks.
- Maximum Wear Protection: Contains high levels of anti-wear additives to protect flat-tappet camshafts and heavy-load valve trains from premature wear.
- Optimised Consumption: The heavier base oils help reduce oil bypass and consumption in high-mileage engines, keeping your classic running cleaner for longer.
Installation Tip: For best results, always change your oil filter when switching to Castrol Classic XL. This oil is ideal for summer use in most classic engines or year-round use in temperate climates where superior film strength is required.
Key Point: Designed specifically for pre-1980 vehicles to ensure maximum engine longevity.
The Castrol Classic range is designed for vintage/classic vehicles and helps to ensure peak running conditions and maximum wear protection for your engine, where modern lower viscosity oils would fail
