LS+ oil is a mix of mineral and synthetic oils. Low smoke and has extremely good lubrication qualities on high load enginge components, such as the connecting rod and bearings. It is best used for chainsaws and clearing saws with a cylinder volume up to 55cm³. It also lowers the engine temperature which extends engine life and gives a very good seizure protection against lean mix as well as carbon related piston seizures. VEF approved.
