What It Does

Bardahl Engine Stop Leak stops oil leaks and seepage by restoring gasket and seal elasticity.

How To Use

Add to engine oil after oil and filter change. One bottle treats up to 6 litres of oil.

Problem

Oil leaks and seepage reduce engine oil levels, increase contamination and can lead to serious engine damage if left untreated.

Possible Causes

  • Hardened or shrunken seals
  • Aged gaskets
  • High engine temperatures
  • Seal material degradation

Solution

Bardahl Engine Stop Leak restores the elasticity of rubber and synthetic seals, stopping oil leaks and preventing further seepage without the need for dismantling.

What are Bardahl oil additives and why should I use them?

Bardahl oil additives are formulated to enhance engine oil performance, reduce friction and wear, protect engine components, and help restore or maintain engine efficiency. They support smoother running, reduce mechanical stress and extend engine life in both petrol and diesel engines.

What is the difference between oil boosters and oil treatments?

Oil boosters and treatments both improve lubrication, but with different focuses.

Oil boosters such as Plasma LXR Oil Booster are designed to strengthen the oil film, reduce friction and improve engine responsiveness.

Oil treatments like Bardahl B1 Preventive Oil Treatment and Bardahl B2 Oil Treatment provide long-term protection against wear, heat and mechanical stress, helping maintain engine reliability.

How do Bardahl oil additives help protect engines and turbochargers?

Products such as Anti Wear Treatment and Turbo Protect are designed to reduce metal-to-metal contact, protect heavily loaded engine parts and safeguard turbochargers from heat and oil degradation. They help maintain lubrication under extreme conditions and support component longevity.

Can oil additives help restore engine performance and reduce engine noise or smoke?

Yes. Maxi Compression helps restore compression and reduce oil consumption in worn engines. No Smoke Treatment reduces excessive exhaust smoke caused by oil burning. Hydraulic Valve Lifter Treatment helps clean and lubricate hydraulic lifters, reducing tapping noise and improving valve operation.

When should I use Engine Flush or Engine Stop Leak?

Engine Flush is used before an oil change to dissolve sludge, varnish and deposits, ensuring cleaner oil circulation and better performance from fresh oil. Engine Stop Leak is designed to recondition seals and gaskets, helping to reduce or stop oil leaks and prevent oil loss without dismantling the engine.
