Hi all Looking for a bit of info on oil grade, my APY S3 is due a change and a quick google search has brought up ALOT of different opinions. In the past i have topped up with edge 5w30 fully but looking online it seems a few people are running 100k plus 1.8 20VT lumps on 10w 40 semi? cars got 113K on it which i know isnt a million miles for a vag lump i just wanted to check before i go spending out on some potentially rubbish stuff cars used on a 30 mile comute everyday (motorway) and a quick b road blast to the grand parents at weekends im used to n/a cars and allways used to run mobile one 10/40 semi or millers on my high mileage ZS180 whats the general thoughts on the above? car does need a top up every now and then on the old 5w30 so should i be going thicker? Thanks in advance all!
