ZIC is good because its synthetic, and high quality, and the most important thing is the chances of geting a fake or used bottle of oil by using ZIC is very low.
Avoid using branded oils such as Honda or Toyota, who knows what kind of crap that is.
If you use ZIC, then you should stick with synthetic.
And any oil change should be 5,000 KM or 3,000 MILES!!! (not 3000 KM). If your using CNG AND Synthetic oil, you can easily make it 7,000 km.
