Its your car and you can try different oils to know which gives the best consumption.
As other post said that not only engine oil is the thing that brings good average, there are many other factors too.
You can try ZIC A+ which is 5w-20 and can notice the average.
But before that I’ll suggest to change company and buy 5w-30 oil from Total (who blends oils for Honda).
Total Quartz 9000 is 5w-30 fully synthetic oil. Give it a try. And don’t forget to add 1/4 of hi-octane in fuel tank with rest 3/4 as regular. I believe it will bring good average for you.
