Comma Classic SAE 30 Mineral Engine Oil

Engine oil is vital for a smooth running engine and vehicle. From lubricating the various moving parts, to cleaning, cooling and protecting the engine, choosing the right oil can make a huge difference. For Classic and Vintage cars from a wide range of eras, it is even more crucial to ensure the oil you use is of the highest quality and viscosity which is recommended by the manufacturer.

Comma's Classic 30 Motor Oil is a traditional, non-detergent motor oil for 4 stroke petrol engines specifically for classic and vintage cars. This oil is designed to stabilise oil pressure at high operating temperatures and is suitable for use in many manual gear boxes from across a range of classic periods. This monograde oil is specially designed for winter/cold temperature usage, and has a lower viscosity to allow for easy flow in a colder engine. It is advisable that this type of oil is changed every 600 miles. A basic winter essential for any classic car owner.

Comma Oil and Chemicals was founded on a real 'passion for performance' in 1965 as a UK-based, independent oil 'blender'. Quickly establishing their products as being the first-choice supplier of engine oils to independent workshop mechanics in the UK, Comma has recently grown to distribute to more than 40 other countries around the world
