Used previously, it's time for an oil change, and since I'm in a hurry, I purchased a budget version of the Takayama. Over time, noises began to occur. I checked the oil level and was simply surprised to see that there is practically no oil in the crankcase. I topped off the oil to the level, ran the car for 400 kilometers, and it's gone again. At first, everything appears to be fine; there is no noise in the engine, and there is no soot. Everything appears to be normal. I went to the gas station closest to me and bought the first synthetic (zik) that I saw. Since then, I have not had any issues when driving. After that, I had the impression that the piston was already covered. I would not suggest using this oil under any circumstances.
