Is it possible to use LS Bellhammer by adding it to the engine oil of Toyota Land Cruiser 70 (diesel engine)?

First of all, LS Bellhammer can be used for diesel engines. The recommended amount to be added is 5-10% of the oil volume.
In addition to Bellhammer, we also have Bellhammer Seven, which is mainly designed to reduce mechanical noise for overdrive vehicles, and Bellhammer Diesel, which is a newly released product for diesel engines. For both of these products, 5-10% of the oil volume is recommended, and we recommend the addition of two bottles per oil change.
