Qualube Classic Monograde SAE20

Qualube Classic Monograde SAE 20 is a non-additive treated engine oil based on carefully selected base oils. This engine oil is a meticulously crafted lubricant designed specifically for vintage and classic engines. Formulated without additives, this engine oil offers simplicity and purity, providing effective lubrication for engines that require a non-additive treatment.

Suitable for older vintage vehicles where an additive based fluid is not required. Commonly used in pre-1950’s applications where modern additives would be unsympathetic to vintage applications and in certain instances cause irreversible damage. Qualube Classic Monograde SAE 20 has been manufactured by our company since 1921 to the tried and tested formula of their day. The absence of detergent & dispersant additives ensures that unwanted “scouring” of the internal components does not take place which can lead to elevated oil consumption and loss of oil pressure.
