Review on Semi-synthetic engine oil ZIC X7 LS 5W-30, 4 l by Micha Kamierczak ᠌

I used to buy zic oil 4 liters. everything is fine on the market, now I decided to take 6 liters, according to external signs it differs from a 4-liter canister in terms of casting, the measuring strip on the canister has irregularities, the date stamp is not clear on the bottom, all other signs of the canister correspond to the original, the smell of oil is identical. I compared canisters in other places where zic oils are sold, there are also flaws, perhaps the quality of the production of the canisters themselves has decreased.
