Choosing the right oil for classic cars

Arguably, the Easter weekend was the first chance for classic car owners to remove the dust sheet, check the vitals of their model, then hit the ground running. As modern engine oils get thinner, questions can arise around suitability for older engines, as Motaquip explains.
The issue, according to Motaquip, lies in oil formulation. Modern lubricants typically comprise detergent and dispersant additives designed to keep engines clean and prevent deposit build-up, but the company says that some classic engines are not designed for these types of additive packages.
It suggests that in certain cases, using high-detergent oils in older engines may lead to problems, as the cleaning action can potentially loosen existing deposits. These could, in some circumstances, contribute to blockages in oilways, increased oil consumption or leaks. Motaquip highlights this as an area where product knowledge and customer awareness are important.
Upselling opportunity
Motaquip believes there is increasing interest in low-detergent, classic-specific oils, which are often considered more suitable for older applications. Products, like 20W-50 multigrade formulations, are engineered with minimal dispersant additives.
Viscosity is a consideration too; many traditional engines were built with wider tolerances than their modern-day cousins. This means they need a thicker oil to maintain effective lubrication – again, the 20W-50 grade delivers. It provides sufficient flow during cold starts while maintaining stability under operating temperatures. Given classic cars spend long periods off the road and stored in garages, this viscosity can be beneficial.
Step forward Motaquip
Motaquip offers a 20W-50 motor oil, a low-detergent multigrade lubricant that is designed for the classic car market. Formulated with few dispersant additives, VOL200 is suitable for naturally-aspirated four-stroke petrol and diesel engines.
This engine oil is recommended in vintage, classic and veteran cars, as well as motorcycles, commercial vehicles and agricultural tractors.
According to Motaquip, for motor factors operating in rural or mixed markets, there is potential to maximise the commercial opportunity that arises this time of year.
A company spokesperson said: “Ultimately, those that stock a classic car oil, like the 20W-50 from Motaquip, will be presented with both responsibility and a sales opening. By bolstering knowledge and understanding, motor factors can better support customers while strengthening their position in a specialist and popular market.”
