This is what happens when you use wrong oil weight.
Due to adoption to hybrid power trains and constant change in technology using correct oil weight is critical than ever before.
This is what happens when you use wrong oil weight or viscosity oil:
.Engines operate under a wide range of temperatures and wrong viscosity oil leads to engine damage and seizure if it's too thick to flow to galleries where it's needed on time
.High oil consumption and increased fuel consumption.
.Engine overheat because oil helps in cooling engine.
.Vehicle system faults,eg VVT.( variable value timing.
Make sure to use correct oil as per Manufacturer specifications.
