Conventional Motor Oil
Sinclair Conventional Motor Oil is designed for older vehicles and/or high temperature climates, whenever thicker oil is preferred or recommended.
The additive system is technologically advanced and includes detergents, dispersants, viscosity improver, anti-wear and anti-friction agents, as well as oxidation and corrosion inhibitors.
The Sinclair Protection Your Vehicle Deserves
Sinclair Motor Oil has been meeting the challenges of balancing protection, endurance and toughness for over 100 years. Today, as always, it provides outstanding protection at a great value.
Sinclair gives you reliable protection against friction, wear and thermal breakdown mile after mile.
