i was abit wary of oiling mine, but in the end just gave it a few coats of stock oil and went with the grein,rubbed it with the grein untill hot,left it etc. i used ballistol stock oil, brought the grein out,with a matt finish and didnt darken the wood too much all in all,
i was stuck on which oil to use...some darken the whole wood, some dont, some leave a matt finish some dont..just be carefull which you use lol
