What is ZDDP?

What is ZDDP? (Zinc Dithiophosphate) Zinc Dithiophosphate is an anti-wear additive used in lubricants.  It is required to protect high load contact points such as camshaft lobes and followers.  It also acts as an antioxidant to extend oil life under harsh conditions.

What is the difference between a mineral and synthetic oil?

What is the difference between a mineral and synthetic oil?

Both types begin with crude oil.  Mineral oil is obtained directly from the refining process, whereas synthetic oils are subjected to chemical processing which alters and improves its chemical structure. Synthetic oils therefore have better performance than mineral oils at higher and lower temperatures, but are inherently more expensive. Millers Oils produce many different mineral,…

Do you have a 2-stroke oil suitable for older 2-stroke engines?

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…

Which oil should I use in my vintage car or bike engine?

Which oil should I use in my vintage car or bike engine?

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…

Is it possible to use a more modern type of oil in these very old engines?

Is it possible to use a more modern type of oil in these very old engines?

Not at all. Modern engines are designed to run on an oil with very low viscosity (thin), such as 0W and 5W. These are too weak for older engines, which have been designed to operate with a viscosity of 20w in winter and 30 or 40 in summer. However, our later formulations, Pistoneeze and all…

What are the specific characteristics and advantages of synthetic oils?

What are the specific characteristics and advantages of synthetic oils?

Here we try to summarise what are the specific characteristics and advantages of synthetic oils? As with mineral oils, there are differing levels of quality within the definition of synthetic oils, but the general advantages are: Better flow at low temperatures enabling thinner oils to be manufactured.
