Hello, I has ea 2011 cr-v and I want to use only Honda oils. So here is my question. Honda uses 0w20, there bulk is Petro Canada and there bottle i'mnot to sure of because every forum I've read here says its either idemitsu or cp. I know for my motorcycle there 10w40 is still idemistu. Is it worth the extra $40 for the bottle oil whether it's idemistu or not or just go with the bulk. I change the oil twice during the 100% once at 50 then agian when the mm gets to 15. Thanks for your help.
