Bell Hammer Gold concentrate is a high-performance lubricant suitable for a wide range of vehicles from passenger cars to sports cars and classic models, and it can also be used in kei cars.
For kei cars, Bell Hammer Light is designed with slightly lower viscosity to suit small displacement, high-revving engines, offering optimized starting and throttle response. However, in terms of safety and basic performance, there is no major difference from Gold.
Therefore, Bell Hammer Gold concentrate can be safely added to a kei car such as Daihatsu Taft in the range of about 5–10% of the total oil volume. Please avoid excessive amounts to prevent oil viscosity from becoming too high. It is compatible with both engine oil and transmission oil and can be used within normal oil change cycles.
