Why? 0w20 is just fine for that engine? Do a UOA and see if there is any fuel dilution, if not just use 0w20. Once I use up my PU 5w20 in my 2006 Accord with the K24 engine, I am going to start running PP 0w20 in it. And my engine has 113K miles on it. I am not worried. Sure you can run a 5w30 in it if you want, but there will be no real benefit. That car will last 200,000 mi or more with the 0w20. Plus you WILL get poor gas mileage with the 5w30. The shop put 5w30 in mine once and I lost MPG big time.
