Castrol act>evo 4T is a modern mineral 4-stroke engine oil suitable for large mono and twin cylinder Touring, Custom and On and Off Road bikes with air cooled engines. It is also suitable for the majority of Classic bike requiring a product with a strong resistance to evaporation.
Castrol act>evo 4T employs the very latest Trizone Technology that gives optimum protection to the engine, clutch and gears even under the most arduous conditions, including sustained operations at high rpm.
The high combustion temperatures in modern 4T engines can cause the oil to oxidize and thicken resulting in starting difficulties and reduced oil circulation; this effect is particularly relevant to air cooled engines where the oil is subject to high thermal stress.
The test below evaluates the resistance of the oil to high temperature thickening in an air-cooled engine. act>evo 4T resists thickening better than conventional oils, offering extra engine protection.
- Trizone Technology for protection of the engine, clutch and gears
- Special wear protection additives for continuous Start Go protection
- Outstanding oxidation and wear control throughout the drain period
- Complies with requirements of catalyst equipped engines
