I’ve been using Maruyama Molybdenum, but I’m thinking of trying your product this time. What oil change interval do you recommend? Also, is it necessary to add it every time?

Oil Change Interval Guideline

Bell Hammer Diesel is a high-performance lubricant additive that helps reduce engine friction, improve lubrication, reduce noise, and enhance fuel efficiency.
As for oil change intervals, it is generally acceptable to follow the vehicle manufacturer's recommended oil change schedule.
However, for older or high-mileage vehicles where condition may vary, an earlier oil change interval (e.g., around 5,000 km) may be advisable in some cases.

Additive Application Frequency

Adding Bell Hammer Diesel with each oil change helps maintain consistent and reliable lubrication performance.
Since the lubricating film degrades and is flushed out along with the oil over time, we recommend adding the product at every oil change.
While many users notice benefits from just one application, continued use provides stronger long-term effects and enhanced engine protection.
