I just looking on what sort of oil to use for a 22r motor that is in a 1998 hilux? standard 15w40 be the best? should I use full mineral or semi synthetic? engine is in pretty good condition has only just done 100 000 and has been maintained well as there is no burnt on oil under oil cap or anything like that.
What type of spark plugs should I use standard copper plugs? or should i upgrade to platinums etc? (I am pretty sure the standard listing for them is just copper plugs)
