Why Do Motorcycles Need Dedicated Additive Chemistry?

A motorcycle engine is quite unique by itself. It has the engine, transmission and the clutch all working together and lubricated by the same oil. Though the needs of each of them could be different and often competing. Let’s look at the engine compared to a passenger car which uses a coolant to cool the …

A question of base stocks

“Unravelling some of the uncertainties” Base stocks are the main constituent by volume in lubricants, accounting for anywhere from 75 to 90% of a passenger car or heavy-duty engine oil formulation. The properties of base stocks can vary enormously from one to another, and they can have a major impact on lubricant performance. Additives are …

PIBs – Polybutenes in Two-stroke oils

Polybutenes used in lubricants are mainly composed of isobutene and often referred to as polyisobutenes, or ‘PIBs’.Polybutenes are produced by polymerisation of a hydrocarbon stream containing isobutene, other butene olefins (butene-1 and butene-2) and butanes. By modifying the temperature of the polymerisation it is possible to produce polybutenes with molecular weights of 260 up to …
