Review on Synthetic motor oil MOBIL SUPER 3000 X1 5W-40, 208L by Nikifor Stoilov ᠌

I traveled 12,000 km in oil as usual, the ride is moderate, I don’t twist it at 4000 rpm. The car does not consume oil, I rarely check the dipstick. During an oil change, I found a film of soot on the dipstick. didn't rub off anything. After some time, washed with new oil. Before that, I flooded ZIC and Hessol, this has never happened.
