More power. Lower fuel consumption. Longer time without repairs. Longer engine life. These are the four reasons why SMT2 synthetic metal conditioner is used both in brand-new cars as prevention and in high-mileage cars — and why it is also used in motorsport, where every lost horsepower is felt.

SMT2 is not an oil additive. It is a metal treatment. The oil is only the carrier here — the friction surface itself does the work. Under heat and pressure (the process starts at 40–65 °C) the formula penetrates the porous surface of ferrous metal and forms a thin, self-renewing protective layer that smooths micro-cracks and prevents metal-to-metal contact. That is why SMT2 does not change the oil's viscosity, pH or additive package — and why it keeps working when the oil film no longer helps: on a cold start, under full load, uphill with a trailer.

More power and better response

Part of the engine's power never reaches the wheels — it is eaten up by friction within the engine itself and lost as heat and noise. In the manufacturer's tests, SMT2 reduces the average friction coefficient by 13 % and increases the critical load by 50 %. In practice it feels like a more responsive accelerator, more stable compression and the ability to stay in a higher gear uphill or with a trailer. That is exactly why it is also chosen by those who want to get more out of their car — including in motorsport and training vehicles, where the engine works at high revs and full load.

Lower fuel consumption

Less friction means less fuel spent overcoming the engine's own resistance. The manufacturer states savings of up to 10 %. In practice, users most often report 3–8 %, and some notice no change at all — much depends on the engine's condition and driving style. The fairest way to check it in your own car is to measure the mileage on a full tank before and after treatment.

Longer time without repairs and longer service life

The protective layer stays on the metal even after the oil has drained into the sump — so it works on a cold start, where most engine wear occurs. Manufacturer data indicate up to 97 % less wear in the friction test and 2–2,5 times longer engine and gearbox service life. Less wear means less metal in the oil, fewer unplanned services and a later overhaul.

What the manufacturer's tests show

• 13 % lower average friction coefficient — less power lost to friction (Stribeck curve)
• 50 % higher critical load and seizure index (GOST 9490-75)
• Up to 10 % lower fuel consumption (manufacturer data)
• Up to 97 % less wear in the four-ball friction machine test (ASTM D-4172)
• 2–2,5 times longer engine and gearbox service life (manufacturer data)
• The protective layer on the metal lasts 8000 km and more (manufacturer data)

Suitable for both new and high-mileage cars

For a new car it is prevention from the very start. The protective layer forms while the friction pairs still have factory clearances and keeps them closer to their original condition for longer. It is the cheapest way to extend engine life — while there is still nothing to fix.

Higher-mileage cars notice the change fastest, because the clearances in the friction pairs have already increased and the protective layer partly evens them out. A quieter engine and smoother gearbox are more often felt there.

For heavy-duty vehicles — diesels, trailer towing vehicles, minibuses, sports and training cars — the benefit is greatest, because it is precisely at full load and high revs that the oil film helps least.

What users notice

The most common observations in user reviews and car forums: a more responsive engine and more pulling power under load, a quieter engine (usually 300–500 km after adding), a smoother gearbox, more mileage on a full tank and easier cold starts in winter. Some users notice no change — most often those whose car was already in very good technical condition and who expected a dramatic change in one day. The real benefit is gradual and long-term.

Which volume to choose

How much to add

The simplest and most correct way is to add SMT2 to fresh oil at an oil change. You can also mix it directly into the oil can and stir thoroughly for 3–5 minutes. After adding, you can continue using the vehicle immediately, without any restrictions. Repeat the treatment roughly at every second oil change.

Is it safe for the engine

SMT2 is compatible with all motor and transmission oils, including energy-saving ones such as SAE 0W-20 / API SN, as well as with modern greases and internal combustion engine fuels. At the recommended concentration, it does not change the basic properties or physico-chemical parameters of lubricants and fuels. The formula contains no solid particles that could clog the oil or fuel filter, and it does not settle even during long periods of standing.

Important: SMT2 is not recommended for final drives with limited-slip (LSD) differentials and similar mechanisms.
