can i put fully synthetic in the copen or does it have to be semi? only asking as i am struggling to find the reccomended 5w 30 in semi other than halfords crap. thanks neill
I've checked the service manual, it reads; 5W-30 (API grade SG or higher) I have a 3L bottle of Magnatec fully synthetic 5W-30. I had bought it for my old Cappuccino. In a couple of weeks it'll go into the Copen instead. Looking on the label it says API grade SL. A quick check on the Internet shows that SL is higher (newer) than the SG. Another quick check on the tinternet tends to show that fully synthetic oils are a better quality, than the semi.
just wanted to know if i could put fully synthetic in without any problems as the service manual says semi synthetic.
