What’s the best oil for older engines?

Castrol Classic XL 20W-50 is a conventional multigrade engine oil of good all round performance, formulated with high
quality mineral oils plus selected additives, ideally suited to older technology and classic car engines.
Castrol Classic XL 20W-50 is designed to meet the motor manufacturers’ requirements for passenger cars and
motorcycles running under normal service conditions, but excluding those equipped with catalytic converters.
The prime recommendation is for pre-1980 petrol engine vehicles requiring a high quality product but with an older
technology additive formulation.

If you are unsure which grade of oil you require, and do not have a handbook, then you can use our Oil Finder to find the original recommendation for your vehicle.
