Yes dear you can use ZIC A+, API SM, SAE 5W 20 in Honda CIVIC, with out any problem , and i assure you that there is no any temprature restirction in using ZIC A+ , it is tested in the hottest weather condition of UAE too and more over when you see the recommendation of HONDA JAPAN , she recommends 5W, and even 0W oils , Further more CIVIC engine is I-VTEC, in which oil also perform like hydrolics in it, and civic engine designe is more compact compare to any other engines so it origanally required lighter lubricants in it .
At the end ZIC A+, is Fully synthetic engine oil and has the best high sheer , high temperature , high load stabality indeed
