If your power steering is leaking oil or the reservoir constantly needs refilling, the cause is usually aged or hardened seals. Due to pressure and temperature, these seals lose their sealing ability over time. With LecWec, you can restore the sealing effect directly during operation without removing the steering rack or pump.
✓Oil leak stop for power steering systems
✓Fast and reliable sealing effect
✓Oil sealing additive without chlorine
✓Seal leaks without removing the steering rack
In power steering systems, polymer seals inside the steering rack, pump, and hoses keep the hydraulic fluid contained within the system. Over time, pressure, temperature, and aging cause these seals to lose their elasticity. The result: fluid leaks at sealing points or the fluid level drops continuously. This is exactly where LecWec takes effect during normal operation.
After being added, LecWec circulates through the power steering fluid and reaches all sealing points within the system. The active formula is absorbed by the seals and helps restore the material to a flexible, smooth, and tightly sealing condition. This allows fine gaps between the seal and metal surface to close again.
In practical use, this means that fluid loss in the power steering system is significantly reduced or completely stopped. LecWec restores the sealing performance of the existing components and enables reliable operation without removing the steering rack or pump.
"I have to report positively that the level matches the oil... unbelievable. [...] I wouldn’t have believed that the steering gearbox would be sealed again after just under a week."

"...nothing was leaking anymore!!!
I am truly very satisfied. At first, I did not believe the product would work, but now I am completely convinced and also saved many hundreds of euros!"

Oil leak at the cylinder base gasket
Verified review (Learn more)"I did not believe it at first, but your product is excellent! [...] I ordered just one can and everything is sealed already, even though you recommend 2 cans, meaning 200 ml, for 6 liters of oil. Many thanks!"

Oil leak problems at the oil flange gasket
Verified review (Learn more)"...which made it even more satisfying when, after around 3 weeks, I noticed that the oil loss had gone down to zero – the steering rack was sealed again!! Even now, after 4 months, the reservoir is still at the maximum level."

Oil leak at the steering rack
Verified review (Learn more)"There was always a small puddle of oil collecting underneath the vehicle. I added 100 ml of LecWec to around 4 liters of oil. Since then, I have driven many miles and was surprised to find that there was no more oil on the ground at all."

Leak at the oil pan
Verified review (Learn more)If your power steering system is leaking oil, this is usually noticeable through oil spots underneath the vehicle, a dropping fluid level, or stiff steering. The cause is usually aged polymer seals. Instead of removing the steering gear, you can address the issue directly within the system.
Step 1: Check the fluid level in the power steering reservoir and determine the total fluid volume.
Step 2: Add LecWec directly to the power steering reservoir at a ratio of 3% of the total oil volume.
Step 3: Turn the steering wheel while stationary and during driving – the additive will circulate throughout the entire system.
The seals absorb the active formula, become flexible again, and fit tightly against the sealing surfaces once more. This stops oil leaks at the affected areas. You avoid removing components and restore the power steering system to a sealed and fully functional condition.
Identify the exact leak location
Clean the hoses and steering rack thoroughly and turn the steering wheel while stationary. This helps determine whether the oil is leaking from hoses, connections, or the steering rack itself.
Check the fluid level regularly
A fluid level that is too low can damage the power steering pump. Keep the level within the specified range at all times.
Inspect hoses and connections directly
Leaks often occur at fittings or porous hoses. Inspect these areas carefully and thoroughly.
Restore seals directly
Power steering systems use polymer seals that harden over time. Through targeted treatment within the system, the sealing performance can be restored.
Use LecWec correctly and monitor the results
Add LecWec to the system at a ratio of 3% of the total oil volume and turn the steering wheel several times. Afterwards, check the sealing performance. In many cases, the oil leak is significantly reduced or completely stopped.
