Operation of P 18

- Ensures anti-wear function and high pressure lubrication, before the creation of the oil film.
- Dramatically reduces engine wear during start-up (the first 500-1000 rpm).
- Reduces ring vibrations and increases compression.
- Extends the life of mechanical parts

- Hyperlubrication of rings, cylinders, piston shaft, turbo, connecting rod, connecting rod bearing, bearing, camshaft, camshaft and hydraulic lifters.

- Hyperlubrication of bearings and teeth in gearboxes and bridges.

- Anti-breakage and anti-wear treatment for racing engines (see dosage).

P 18 : Híbridos y Stop and Start 

Hybrid vehicles and those equipped with the Stop and Start have great advantages when operating with P18

Toyota Hybrid de Hi-TecEngines always generate more carbon at start-up. C 99 limits these effects in new or older vehicles and contributes to lower fuel consumption (see anti-pollution testimonials).

The first cause of engine wear is generated in the first 500 / 1,000 rpm, during start-up.

1 - At each start-up, Mecarun P18 protects the engine against wear and seizure, as it does in racing engines, at critical moments (rupture of the lubrication film). It allows a significant reduction of the oil temperature and of the friction energy generated by the deposits of rubber, varnish and oxidised oil (contributes to fuel savings).
2 - P18 reduces vibrations (second cause of wear). The engine runs better and is quieter.
3 - P18 is combined with the metal of rings, pistons, cylinders, camshafts, connecting rods, etc....
P18 fuses with the crystalline layer of the metal, allowing the metallics to interpose themselves in the friction between engine parts, considerably reducing wear.
The investment in the P18 is more than recouped, due to savings in consumption and maintenance operations.
Mecarun P18 is recommended for all 2 and 4-stroke engines, petrol or diesel, for gearboxes, axles, for degreasing injectors and hydraulic tappets and to prevent seizure of racing engines. Le P 18 is suitable for passenger cars and commercial vehicles, for transport vehicles, for agriculture, industry, marine ...

Annual overhaul of outboards, Volvo Penta 2 and 3 cylinder turbo engine 2000 series.

Here, 6 engines: 2 treated from the beginning with Mecarun and 4 untreated.

The 4 engines without Mecarun show significant scoring on the top of the cylinders (wear of 9 and 12 hundredths of a mm)..

All 6 engines had been ground on the same date. The 2 treated with Mecarun P18 still show traces of machining. The wear measured with the dial gauge is considered negligible compared to the other engines.

Mecarun P18 is a permanent treatment of the metal surface

Mecarun P18 follows the reaction of synthetic hydrocarbon metallizers. At the beginning of its manufacturing process, Mecarun P18 is a blend of EP (Extreme-Pressure) metallics composed of natural anti-corrosion ingredients, anti-wear components and antioxidants.

It is equally important to know what Mecarun P18 does not contain. It does not contain chlorinated paraffins, PTFE (Teflon), fluorine, solvents, viscosity optimisers, molybdenum disulphide, zinc, sulphur, graphite or any other solids.

SUMMARY : Le Méca-Run P18 augmente le rendement, la durée de vie et réduit les coûts de maintenance non prévus des moteurs et boîtes de vitesses. Le Mecarun P18 reduces the energy lost in friction and contributes to protecting the environment.

Mecarun P18 is a state-of-the-art permanent anti-friction surface treatment.

Metasliding agents are carried by the oil and adhere to the carbon of the metal, modifying the amorphous layer of the metal (crystalline layer). The layer resulting from the P18 treatment does not exceed one micron, although it maintains its super-sliding and anti-wear function.  The P18 particles in suspension will always make up for the possible detachment of molecules from the layer created when it is subjected to certain circumstantial cuts, so that the engine elements will always remain new..

Benefits of Mecarun P18 in the engine

- Permanent sliding of any metal surface (even without oil pressure).

- Reduced operating temperature at all friction points.

- Rise in compressions as a result of reduced ring vibrations.

- Reduction of oxidation, thermal decomposition, corrosion and wear.

- Low energy demand in hot and cold start-up and under all weather conditions.

- It does not impair the viscosity and does not age the lubricant.

- It has a long-lasting effect.

- Longer adhesion to the metal between oil changes.

- Maintains its protection even when the oil loses its properties or is cut off by the presence of water

- Prevents deposits, combustion residues and abrasive particles from adhering to treated surfaces.

- Reduction of the number of abrasive particulate pollutants in the exhaust, for all types of engines.
