"We recommend Motor Defender to our customers during oil changes because it bonds very well to metal surfaces in the engine and helps level out micro-irregularities. This significantly reduces friction, the engine runs more smoothly, and at the same time, it is better protected during normal operation. I see it as a very good combination of regeneration and long-term prevention in one step. In engines where it is used regularly, component wear is noticeably lower, and the entire aggregate runs more healthily and smoothly. I definitely recommend it to anyone who wants to give their engine better protection and a longer lifespan."
Radek Novotný
Fleet manager, Olomouc, Czech Republic
"We use Motor Defender in our company fleet during every oil change because we need the most stable performance and lowest operating costs possible for cars in daily operation. After prolonged use, we can see that the engines run more quietly, have a more balanced performance, and our fuel consumption on long routes has demonstrably decreased. I also appreciate that it displaces moisture and helps protect metal parts inside the engine from corrosion, which is very important from the perspective of long-term protection. Overall, it gives us the confidence that the engines are better protected even under high loads."
Martin Konečný
Equipment mechanic, Třebíč, Czech Republic
"We use Motor Defender not only in engines but also in the gearboxes and differentials of our equipment, where components are exposed to high loads over the long term. In practice, it is visible that friction is reduced after application, the mechanisms run more quietly, and parts wear out more slowly even under demanding operation. From a technical point of view, I also appreciate the formula without Teflon, chlorine, and ceramics, so no substances enter the system that could negatively affect the lifespan of the mechanisms in the long run. For me, it is a functional solution for both prevention and ongoing regeneration. Within the equipment we maintain, Motor Defender has truly proven its worth."
Jiří Holub
Car enthusiast, Liberec, Czech Republic
"I tried Motor Defender in a car with over 500,000 km on the clock, and the result really surprised me. After adding it to the oil, the engine quieted down significantly, the running is smoother, throttle responses are brisker, and the whole car feels much more refined. I feel as if the engine has come back to life and runs almost like new, which I really wouldn't have expected at such high mileage. The difference is noticeable not only while driving but also in the overall performance of the engine. For me, this is a product that makes sense even for older cars, and I would definitely recommend it to other drivers."
