honda's own patented blend was formulated by Idemitsu lubes Japan, Between oil blending companies - the formulation is bought by others to service local industry (called royalty if you are confused)
just like Valvoline (USA) pays BASF (DE) to use their Glysantin formulation coolants that are sold in USA.
On the same coin - the blending additive is bought by local oil blenders/fillers and added to the specified base stock then packed and sold. - Simple operation.
Please dont try to overthink this - Honda civic is a cheap car with a cheaply made engine which requires cheap maintenance otherwise the entire worldwide sales of the civic will come to a halt if they started to specify zeus piss as engine oil.
Read the user manual provided with it, It has the oil performance specifications written in it - just follow them.
