Review on Semi-synthetic engine oil GENERAL MOTORS Semi Synthetic 10W40, 4 l by Micha Bukowski (Pax) ᠌

Mitsubishi Carisma 1.6 At high engine speeds, it burns out strongly, with replacement intervals of 7-8 thousand km. dirtied the engine terribly (sludge). It is possible that it is impossible to roll it over 5 thousand. km, but in such conditions with a short change interval it is useless, there are a lot of options for other more stable and strong oils. I switched to Idemitsu 5w40 synthetics (I don’t think it’s ideal) and I ride with a level from replacement to replacement for 8 thousand. km.
