Review on Synthetic engine oil GENERAL MOTORS Dexos2 Longlife 5W30, 2 l by Mateusz Burzyski ᠌

I took the car from scratch. Up to 70 t. Km I drove this oil. Replacement at 10k. At the next replacement, having driven 2tkm, I looked into the oil filler neck, and there was shoe polish. If, as some write here, I traveled more - hello capital. And leaked just in time. Washed the engine with frequent oil changes. Interval 2-5 tkm. Approximately, after 20 tkm, the engine became quite clean. I tried different oils (total, liquid moth, carry), but returned to the original. Second change, everything is fine.
