HI,

For clarification, do you mean for noises such as noisy lifters or valves

HI,

If so, then the best is Liqui Moly MOS2 Anti-Friction Engine Treatment

What’s the difference between liquid Moly and Lucas, because I add Lucas and thicker oil and nothing better happens
BMW Mechanic: Eric, Automotive Repair Shop Manager replied 10 months ago

HI,

Lucas is a close 2nd to liquid moly. There are some competitive differences in formulation. If the Lucas did not help at all, the Liquid Moly wont make a difference, which means that whatever is the cause of the noise - lifter, valve, cam, crank or rod bearing - will need to be repaired
