Review on Semi-synthetic engine oil IDEMITSU 5W-40 SN/CF, 200 l, 199.6 kg by Celina Kedzierska

Even though the oil could have been used for 10,000 kilometers, just like oil from other manufacturers, it had to be refilled multiple times, which was a major inconvenience. It sounds as though there is no oil in the engine at all, and the engine is very noisy. It does not have a synthetic odor; rather, it smells like mineral oil. It is no longer relevant because it has been superseded. My Honda will never again be filled with oil of this "Japanese" variety!
