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.

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

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.
