Ok thankyou its just i need to add Wynns Hydraulic Valve Lifter TreatmentI know on the Z12XEP it held 3.5 Litres with Filter. I assume the A12ZER is the same or similar? 4 Litres should be enough.
Hmmm :/ i had first service last month and just wondered how much addative to add to my oil?? And hmm yer it could but vauxhall say they dont know what to do and they cant hear anything so i guess its up to meWhat info do you need? If your talking about sticky lifters try changing the oil and filter first. I don't agree with all the additives you put in. Some can be harmful to rubber seals over time..
