SAE 30 engine oils are based on high-quality, age-resistant mineral oil raffinates with a good viscosity-temperature behaviour. Additives are added depending on the application. SAE 30 oils for classic cars are mostly offered unalloyed.
SAE 30 is the name of the SAE class according to which the engine oil was classified. These are monograde oils which are mainly used at temperatures above freezing point. SAE 30 oils do not have good cold flow properties. Use them only in spring, summer and autumn. The number '30' refers to the kinematic viscosity at 100 °C.
