If Level of Engine oil is OK, check with these priorities:
1. Your clogged Air Filter
2. Clogged Oil Filter
3. Clogged Fuel Filter
4. Check your Clutch plate
5. Check pressure plate
If any one of them will be weak or not O.K, then car will be felt heavier + more sounds will emerge out.
I hope you will find issue from one of above 5 factors
77K mileage is more referring to problems and issues which many users have previously experienced or faced in Cultus
