MA Professional Engine Doktor 444ml - Engine Oil Additive

Purpose and Specifications

MA Professional Engine Doktor is a high-performance oil additive that stabilizes oil viscosity and keeps it strong up to 150°C engine temps, cutting oil burn-off in gas and diesel motors. This 444ml bottle treats up to 4 liters of oil, sealing piston rings to boost compression, quiet engine noise, and restore lost power in worn engines.

  • Reduces oil use by sealing leaks, perfect for high-mileage cars over 150,000 km.
  • Quiets and smooths rough-running motors under heavy city loads or towing.
  • Extends engine life with superior lubrication that fights friction in turbo and LPG setups.
  • Works in new or old engines, including gearboxes and diffs.

When to Use / Replace?

Add at every oil change, roughly every 10,000 km or 12 months. Ideal for engines smoking, guzzling oil, or losing power. Shelf life is 3 years unopened; use within 6 months once mixed. Safe from -30°C cold starts to 150°C high-heat runs.

FAQ

Q: Can I use it in my daily driver?
A: Yes, pour into warm oil at change - one bottle per 4L keeps your engine quiet and efficient for 10,000+ km.

Q: Does it work on turbo diesels?
A: Absolutely, it protects turbos under extreme loads like city stop-go or heavy vans.

Q: How soon do I see results?
A: Notice less smoke and smoother idle after 200-500 km of driving.

Packaging — built to arrive intact

Oil and lubricants are liquids, so we pack every order to reach you perfectly. This is the care that goes into each parcel:

Sealed, leak-proof bagEvery bottle is sealed inside its own hermetic bag, so even a cap loosened in transit can never reach the rest of your order.
Absorbent paper cushioningAbsorbent paper fills the empty space, softens every knock and soaks up any spill instead of letting it spread.
Branded sealing tapeEach box is closed with our own branded tape — a clear sign it left us fully sealed and untouched.
Handled as fragileClear fragile markings tell every courier to carry it gently, so your oil arrives exactly as it left our warehouse.

The result: a clean, sealed, undamaged parcel — because getting the oil to you intact is the whole point.

Returns

14-day right of withdrawal under EU consumer law. Items must be unused and in original, unopened packaging.
