2.4 liter knocking noise below 10 mph

Hey, just curious what this could be or should i bring it in? Been about 2 and a half years with this vehicle and there seems to be a steady knocking noise when accelarating in drive or reverse at low speeds (below 10 mph) and has been doing so for quite some time. Never really put much thought into it and im at 25k miles. Is this something major i should bring back to the dealership? Im on basic warranty 30 k miles

In Oz the recommended fuel for the 2.4L TigerShark is Premium (92 or 93 RON - high octane) using the lower octane fuel results in the pre-ignition of the fuel & valve knock.

FIAT but the MultiAir on the Chrysler 2.4L TigerShark engine.
Oops! OZ Premium fuel is 95 or 98 RON.
It's the same engine, BUT I don't understand why Australia & USA have different recommended fuels!?

BUT use what your manual states. 87 AKI.

When did you start to notice the knocking? (a thud or more of a tick?)
Is it getting louder?

Does it get faster with the revs?
Dose it disappear as the revs increase?
Have you done the specified oil & filter changes?

Have you been topping the oil up for 2 and a half years?
Are you using the recommended 100% synthetic oil? Or something cheaper?
Are you needing to top up more now?


There are too many variables!
Perhaps a visit to a mechanic is required?

Knocking notice: almost since the beginning of owning the car

Appears upon accelaration steadily and does not seem to dissappear

Specified oil changes, yes

Topping off oil, one time in the winter it went below fill line during warm read at tip of dipstick. Immediate oil change the following day as low oil came on during a turn.

Always used full synthethic 0w-20
