Car:- 07 Alto LXi
Mileage:- 15k kms

Just noticed when I took out car to highway this weekend. Constant knocking whenever accelerator is depressed. Especially after 80. Had to continue by journey at 60-70 till I reached my destination.
Car doesnt knock much when not fully warmed up. But starts doing it after a few kilometres.
Will knock in 1st gear also on sudden acceleration. Sometime if you pump the throttle hard while engine is idling, you will feel a faint knock sometimes.

Car was serviced one month ago. Injectors were cleaned.
I always use IOC xtra premium 91octane.
Tanked up before this drive. Fuel Pump is the same from where I always fill.

Any possible causes?

P.S.>> When I drive alone, knocking is reduced. But goes up to alarming levels when friends/family travelling alongwith.
