MotoDoctor™ Engine Protector for Smoother Engine Operation

Help protect vital engine components with FixBlitz MotoDoctor™ Engine Protector, a 325 ml engine oil additive for petrol and diesel engines. Powered by Anti-WearAgent™, this easy-to-use formula is designed to create a protective lubricating film around internal engine parts. The resulting barrier helps reduce friction, wear, and operating noise while supporting smoother engine performance.

Every engine contains moving metal components exposed to repeated heat, pressure, and friction. Over time, these operating conditions can contribute to wear and reduced efficiency. MotoDoctor™ supplements the engine oil already in the system, helping it maintain a stable lubricating layer across vital components. One 325 ml bottle treats up to 6 litres of engine oil.

Protection for Hard-Working Engine Components

MotoDoctor™ is formulated to support the lubrication of internal parts during everyday driving. Its protective film helps reduce direct friction between moving components and may contribute to quieter, smoother operation. By reducing friction-related heat, the additive also supports the conditions needed for dependable engine performance.

The formula can help improve sealing between engine components, which may reduce oil consumption in engines affected by normal operating wear. It is also designed to help engine oil retain its useful performance for longer. Results can vary according to engine condition, mileage, maintenance history, and the oil already in use.

Key MotoDoctor™ Benefits

  • Helps reduce friction: Creates a lubricating film around moving engine components.
  • Supports wear protection: Supplements engine oil to help protect vital internal parts.
  • Promotes smoother operation: May help reduce mechanical noise associated with friction.
  • Supports oil retention: Improved component sealing may help reduce oil consumption.
  • Simple oil-filler application: Add the product directly through the engine oil filler opening.
  • Broad engine compatibility: Suitable for both petrol and diesel engines.

Simple Addition to Routine Vehicle Maintenance

No specialist application equipment is required. Shake the bottle, confirm the engine’s oil capacity, and pour the appropriate amount into the oil filler opening. The stated mixing ratio is one 325 ml bottle for up to 6 litres of engine oil. Avoid overfilling the engine and always check the dipstick or electronic oil-level display before and after application.

MotoDoctor™ has a clear liquid appearance with a light amber tint, an approximate density of 0.85 g/cm³ at 20°C, and a flash point above 200°C. It integrates into the existing engine oil, allowing the lubricant to circulate the additive through the engine during normal operation.

For Petrol and Diesel Vehicles

This engine protector is suitable for drivers seeking an uncomplicated way to supplement routine lubrication in petrol or diesel engines. It can be useful for higher-mileage vehicles, frequently driven cars, work vehicles, and engines where smoother operation and wear protection are priorities.

MotoDoctor™ is an oil additive, not a substitute for the correct engine oil or scheduled servicing. Always use the oil grade specified by the vehicle manufacturer and continue to follow the recommended oil-change intervals. If your vehicle has a known mechanical fault, warning light, unusual knocking sound, or manufacturer restriction concerning additives, obtain professional advice before use.

With a clearly stated dosage and direct-to-oil application, FixBlitz MotoDoctor™ Engine Protector fits easily into regular vehicle care. Use it to reinforce lubrication, help limit friction, and support smoother operation across the engine’s vital moving components.

Customer Reviews

What our customers say

Marco R., 42 ★★★★★
I added it during an oil service on my older diesel estate. The engine seems smoother at idle, and the 325 ml bottle was straightforward to use.
Daniel K., 35 ★★★★★
I used the correct proportion in my petrol hatchback and checked the dipstick carefully afterward. Application was clean, quick, and much simpler than I expected.
Sofia M., 29 ★★★★☆
My commuter car sounded a little less harsh after the treated oil had circulated. I especially liked that the dosing instructions were easy to follow.
Robert H., 58 ★★★★★
I tried this in a high-mileage work van at its regular service. Idle feels steadier to me, although I will keep monitoring the oil level as usual.
Élodie P., 46 ★★★★☆
The bottle covered my engine’s oil capacity with some careful measurement. After several drives, the motor appears quieter when warm.
James T., 63 ★★★★★
I added MotoDoctor™ to my petrol saloon after checking the handbook and oil level. The engine now feels smoother during ordinary city driving.
