Review on Synthetic engine oil MOBIL 1 FS 0W-40, 4 l, 4 kg by Mateusz Roczon ᠌

I've been pouring only it into my old w203 for about 10 years. when I bought the car, I remember the oil was always black as soot. just fill in a new one - you will drive 100-200 km, at least go to the replacement again. I even took it off, cleaned the pan and washed it with a spindle. helped a little, but not so much that it became completely clean. Recently, I began to notice that it seems like the color of the oil lasts longer. from replacement to replacement, the color practically does not change. black but transparent. Apparently they pressed the basement production :)
