Rislone Engine Treatment is a lubricating oil that cleans and protects. It penetrates the areas of the engine where deposits form, such as the valve seats, piston rings and bearings. The treatment works against the deposits and allows them to be trapped in the oil filter. Engine deposits work negatively on parts, causing altered tolerances, stuck parts and noisy lifters.

Liqui-Moly Tappet Stop Noise works in a similar way as an oil additive. It works for all types of engines, including diesel. It also works with any type of engine oil. It cleans engine parts, including worn lifters, and dampens the noise these parts can make.

A noisy lifter typically makes a knocking or pinging sound in the engine compartment. The noise is caused by a loss of oil pressure within the lifter. This can happen from not changing the oil at regular intervals or from using the wrong weight of oil. It can also happen from lifters simply being worn. Oil additives, such as Rislone and Liqui-Moly, protect worn parts and help stop leaks.
