I have tested Shell Helix Plus 15W-50 semi-synthetic for my B16A, and it sucks. Sometimes the VTEC didn't even engage!. It sure is smooth, but it's too thick.

I'm back using Idemitsu 15W-40 mineral which I've always used all these while, definitely much-much better... but needs some running first. Most important, it's cheap.

There is no 1 engine oil that is good for every engine. Every engine might have different taste.

I don't know about your place, but here in Miri... Idemitsu can be found easily.

Honda VTEC oil = Idemitsu semi-synthetic 15W-40
