mk4 golf 1.6 8v 1999 auto
Hello all,
Basically the car went in for a service today and I have 5 litre of car lube
10/14 semi synthetic oil which has been used for the last 3 years in it. Its first service was done at a vw specialist and they used this infact it was quantum oil but same spec.New local garage I'm now using said I've been using the wrong stuff and reckon it should be 5/30 fully synthetic ?
Can anyone confirm which grade goes in ?
I asked them to hold off on the oil change while I dug in to it, they weren't best pleased to be questioned but hey ho..
