PROFI-CAR Hydraulic Lifter Additive 300ml

PROFI-CAR Hydraulic Lifter Additive is a fast-acting, semi-synthetic cleaning additive for engine oil, specially developed to clean and help restore the function of hydraulic valve lifters (hydraulic tappets) affected by impurities and deposits. The manufacturer describes it as a treatment for reducing rattling caused by deposits and improving the functional reliability of hydraulic lifters.

Deposits and contamination inside the engine can interfere with the proper operation of hydraulic lifters and may result in characteristic rattling or ticking noises. PROFI-CAR Hydraulic Lifter Additive is formulated to help dissolve and remove these deposits, supporting smoother operation of the hydraulic lifters and the engine’s valve train.

In addition to cleaning hydraulic lifters, the additive helps clean valves, oil passages and bores, as well as piston-ring grooves and their surrounding areas. This makes the product suitable not only for hydraulic-lifter contamination but also for cleaning deposits within the engine interior.

The formulation also contains high-pressure and anti-wear additives, providing additional protection for components exposed to mechanical loads. PROFI-CAR further specifies corrosion and oxidation protection, while the additive remains in the engine oil during the treatment period until the next oil change.

The product can be used when hydraulic lifters are rattling because of impurities or deposits, as well as as a preventive treatment to help maintain their functional reliability. The manufacturer also identifies contamination around the piston-ring area and general cleaning of the engine interior as application areas.

PROFI-CAR Hydraulic Lifter Additive is therefore intended as an engine-oil cleaning treatment for hydraulic lifters and internal engine deposits, helping improve cleanliness and support proper component operation without replacing the engine oil itself.

FAQ:

What is PROFI-CAR Hydraulic Lifter Additive used for?

It is designed to clean hydraulic valve lifters and help restore their functionality when deposits or impurities cause rattling or improper operation.

Can it reduce hydraulic lifter ticking or rattling?

Yes. PROFI-CAR specifically states that the product helps reduce rattling of poorly functioning hydraulic lifters caused by deposits.

Does it clean the engine oil system?

It is added to the engine oil and helps clean deposits from hydraulic lifters, valves, bores and piston-ring areas.

Can it clean piston-ring deposits?

Yes. The manufacturer specifically lists cleaning of piston-ring grooves and their housing among the product’s functions.

Does it provide anti-wear protection?

Yes. The formulation contains high-pressure and anti-wear additives.

Does the product remain in the engine oil?

Yes. PROFI-CAR states that the additive remains in the engine oil and should be left in the oil until the next oil change.

Can it be used preventively?

Yes. The manufacturer states that it can be used for functional reliability and prevention, in addition to treating existing deposit-related hydraulic-lifter problems.

How much engine oil can one treatment cover?

The official data sheet specifies one treatment for approximately 3–6 liters of engine oil.

Does it replace engine oil?

No. It is an additive used together with the engine oil and does not replace the correct engine oil or the vehicle manufacturer’s oil-change schedule.
