Castrol Power1 A747
Castrol Power1 A747 is a low ash, part synthetic racing lubricant specially formulated for use in multi-cylinder, water- cooled two-stroke engines fitted to road racing machines, where combustion chamber deposit control is essential. It also contains special additives to prevent throttle slide sticking in wet weather conditions and may be used at fuel/oil ratios up to 40:1.
Reliable performance at elevated operating temperatures helps Castrol Power1 A747 maintain consistent lubrication where heat stress would otherwise shorten fluid life.
The formulation is engineered to maintain engine and component cleanliness, helping to prevent deposit build-up and supporting efficient operation throughout the service interval.
Castrol Power1 A747 is intended for racing applications only. It is not suitable for autolube systems and should not be mixed with any other oil, whether mineral, vegetable or synthetic.
Castrol Power1 A747 is manufactured to Castrol’s standard tolerances; users should consult the safety data sheet for handling, storage and disposal guidance.
