tgdi using 5.6l? is the sump really that big eh?
i guess its normal tho for high performance engine to store more oil. iinm conti cars also use more than 4 liter of eo right

i guess its normal then, cos 1.6 na just need 3.8l of engine oil. turbocharge is another level no wonder my pomen recommended to use oil sump extender for 4g93t. to store 6 liters of eo. maybe better for heat dissipation

port injected no need, if direct then have to check the valve dirty or not.

the truth is I think need to change just like what u said to they just want lower the perceived costs.

just like preve and other proton cars, upon reach 100k km after timing belt change mostly will need to change the water pump and tensioner bearing, cos this two parts is wear and tear parts. some waterpump can holds up to 200k km. but some only lol.
