Review on Synthetic engine oil Takayama 5W-40 API SN/CF, 4 l, 4 pcs by Mateusz Rzeczycki ᠌

Since I've been taking this oil for a second year, everything is satisfactory to me. Since the automobile is quite new and acceptable for all seasons, I only add strictly synthetic 5w-40. Wintertime starts with a half turn at any temperature without thickening. In the summer, there is no overheating at high highway speeds because the engine works so smoothly. There is no soot, thus there is no need to top up.
