CASTROL CLASSIC XL 20W-50

Why Choose Castrol?

Castrol Classic XL 20W-50 is a conventional multigrade engine oil that offers strong all-round performance and is precision-engineered for older technology and classic car engines that demand higher viscosity. This 20w50 engine oil has been formulated with high-quality mineral oil plus carefully selected additives, meaning that it meets the needs of classic engines from the base upwards.

Choosing Castrol Classic XL 20W-50 for your vintage or classic car means you will benefit from premium engine wear protection and optimal performance, both of which are vital to the longevity of older engines. If 20W-50 engine oil is the right grade and consistency for your vehicle, there is no better product to meet your needs than the Classic XL 20W-50 formulation from Castrol.

To further protect classic engine components, the oil includes anti-wear additives that reduce metal-to-metal contact under load. This extends engine life and maintains performance, especially under the stop-start conditions common in classic motoring.

Castrol Classic XL 20W-50 offers higher viscosity when cold compared to modern low-viscosity oils, which makes it ideally suited for petrol and diesel engines in classic cars and motorcycles. This high viscosity delivers superior oil pressure and film strength on start-up. Castrol Classic XL continues to offer effective lubrication in warmer temperatures without excessive thinning, which helps reduce the high oil consumption and leakage that are common issues in older engines.

For classic vehicle owners, selecting the right oil is a crucial part of engine maintenance. Castrol Classic XL 20W-50 supports older technology and classic car engines with the confidence of a heritage brand that understands period formulations while also delivering quality mineral oils for modern engines.
