Hi marios221,
Should be the oil, not the gas.
From what I understand, synthetic oils are not recommended for this engine, it will cause the hydraulic lifters to go bonkers.
Oil treatments will make the matter worse.
Servicing or replacement of the lifters is the best way but you can try replacing the oil and see if it helps. It might take quite some time before the lifters gets to perform well again.
