Product overview
Viscoplus for Oil is a motor-oil additive that stabilises the oil's viscosity and helps maintain consistent oil pressure as the engine runs. As motor oil ages or comes under thermal stress, its viscosity can drift from its intended range, which affects how well it seals and lubricates moving components.
By supporting the oil's ability to form a stable lubricating film, the treatment helps reduce oil consumption, improve compression through better sealing, quieten engine noise and reduce wear. It is compatible with all commercially available motor oils and is not suitable for motorcycles with a wet clutch.
