In 1965 Comma Oil was born and quickly became the major supplier to the Independent Vehicle Workshops and DIY motorists of the time. The motor oils that Comma produced then have, over the years, been updated to meet the demands of the newer technology engines leaving the Classic cars of the 60s, 70s and 80s without the motor oil for which they were designed.
The Comma Classic Range re-introduces not only the original 20w50 Motor Oil for the period but also includes the SAE 30 and SAE 40 non-detergent mono-grades formulated as they were in the past.
Why do Classic cars need classic oils?
Modern Oils (= fully & semi synthetic oils), especially lower viscosity grade oils are often too thin for engines in older cars. Oil additives in modern oils tend to dry up old gasket materials like leather, cork & felt - Resulting in Oil Leakage. Whilst modern engine oils do offer benefits in cold weather conditions, most classic & vintage cars are driven during spring/summer.
Detergent Additives in modern oils can clean up old engines which can lead to lack of compression and other engine issues!
