So, I have put it in 3 cars, engine and gearbox, it made the gearboxes smoother, especially in a Peugeot 206 that had an issue, it wouldn't shift gears easily, especially the outer ones. Lately, it was added to a Corsa D and in the engine, even though I used 5-40 instead of 5-30 due to the mileage, it had an instant idle consumption of 0.4-0.5 compared to 0.6-0.7 it had before

It is not a chemical additive with anti-friction additives that usually alter the viscosity of the oil.

It polymerizes and adheres to the metal, creating less friction. Ideal for those with old engines, they become quieter.

I imagine it does what it is intended for. I didn't notice anything different in the motor anyway, I don't know if anyone understands anything, as long as it works.

I tried it and I was very satisfied! It reduces friction, wear, noise, temperature, it is not affected by oil changes, and it has a long lifespan. I tried several additives but didn't see any differences, like Militec none!!!

It's not wow and great!!!! Does it really improve the engine's friction... okay... not much of a difference... like all the other oil additives from other companies in terms of nanotechnology... A German one that I tried, for example, had completely messed up my travel computer... it was stuck at 5 liters per kilometer... it only got unstuck after 5000 kilometers!!!!!
