Why is there blue smoke from the exhaust sometimes when I accelerate hard in my Oshan X7?

Occasionally, I see bluish smoke from the exhaust when I accelerate aggressively. Could this be due to oil burning inside the engine? What are the most likely causes for this in a relatively new Oshan X7?

Blue smoke indicates burning engine oil inside the combustion chamber. Possible reasons:

Worn piston rings o r cylinder walls allowing oil leakage.

Faulty valve stem seals leaking oil into cylinders during combustion.

Turbocharger oil seal leaks, common in turbo engines like the Oshan X7.

Blue smoke is a serious sign and shouldn’t be ignored, as it means oil is not staying in the lubrication system but being burned, leading to engine damage.

Action:

Get a full engine check including compression test.

Inspect turbocharger seals and valve seals.

Use recommended oil and ensure timely servicing.
