INNA LILLAHI WAINNA ELAIHI RAJEUUN' I can only pray for the mechanic and your known person.
Brother if engine is absolutely fine, then I would sincerely suggest to use 5w-30 only, preferably Fully Synthetic, meeting API SN / SN Plus, and / or ILSAC GF-5 criteria.
In 5w-30: Total Quartz 9000 Future Series (Best Value for money), ENEOS Sustina (better than Total but a bit expensive), Kixx, and lastly, PSO (the cheapest option in all of these 04)
