Mineral Engine Oil

Mineral engine oil is refined directly from crude oil rather than chemically engineered, and it remains the recommended lubricant for plenty of older engines, classics and general-purpose machinery. Where a handbook specifies a mineral oil, using one is usually the right call. Enter your registration into our oil finder to confirm what engine oil your vehicle needs.

Mineral based engine oils have a less uniform molecular structure than synthetic stocks, so they thin out sooner under sustained heat and need changing more often. On an older engine with generous clearances and a shorter service interval, that trade-off is often perfectly appropriate, and it keeps the cost of a service down.

Mineral oils are most commonly found in the thicker multigrades used by older engines. Browse 15W-40 engine oil and 20W-50 engine oil, or see 10W-40 engine oil for a middle option. 

It is typically specified for older petrol and diesel engines, classic cars, agricultural and garden machinery, and applications where a straightforward, frequently changed lubricant is preferred. Some engine rebuilds also start on a mineral oil during running-in before switching.
