Comma's Classic Engine Oil range will comprise a Classic 30, Classic 40 and Classic 20w50 attractively packaged in five-litre 1950s-style tin.
With the country's classic motors estimated to be worth at least pounds 2.5billion, the specially-formulated lubricants are ideal for cars built in the 1960s, '70s and '80s.
Modern engine oil is too thin in viscosity for classic cars and the additives used in modern lubricants can corrode materials used in older head gaskets, such as leather, cork and felt.
In addition, detergent additives in modern oil can cause a lack of compression in classic engines and, although contemporary oil offers better protection in cold weather, most classic vehicles are driven in spring and summer, with over 70 per cent of historic vehicles travelling less than 900 miles per year.
