Review on Synthetic Motor Oil Gaspromneft Premium N 5W-40, 4 l by Mateusz Majchrzak ᠌

Without chemical analysis, it is impossible to judge the whole oil picture, but some conclusions can be drawn from subjective (and some objective) parameters. For example, it is clean under the valve cover, the engine whispers, winter launches do not disappoint, for the SN-class the price is just a fairy tale, there is an authentication code (via SMS or via the website). Got pros: 1. Prevalence in sales 2. Anti-counterfeit protection (factory) 3. Excellent price/performance ratio 4. Has the conformity and approvals of a wide range of car manufacturers. Got cons: Not a drawback, but an unpleasant feature - GPN oils at branded gas stations are more expensive than at other points of sale.
