Which engines would use Millers Classic Sport 20w50?

Vintage cars/bikes, ie. pre-WW2, had very primitive oil filtration systems and used non-detergent oils, such as our Millerol range. The Millerol range contains anti-wear and anti-corrosion additives, but does not contain detergents which can attack yellow metals.  A lower viscosity oil would be needed in the winter, such as Millerol 30 and a higher viscosity…

Do you have a 2-stroke oil suitable for older 2-stroke engines?   Yes.  Traditionally, the most popular oil for 2-stroke engines, was an SAE 40 mineral oil.  However modern 2-strokes require a low smoke, semi synthetic 2-stroke oil with a much lower viscosity, SAE 15.  Older 2-strokes, do not appreciate these thinner oils, so Millers produce…

Viscosity is a measure of the thickness of an oil.  The viscosity (thickness) of the oil at low and high temperatures is measured on a scale determined by the Society of Automotive Engineers and given a number known as the SAE number.  Therefore SAE 30 oil will be thinner than an SAE 40.
