having got an oil temp sensor fitted to one engine but not the other i struggling to work out if i want one of these so could someone help me out - if my oil pressure light came on i would engine off immediately pretty much regardless. if i hit too oil oil temps i would stop fast but not immediately especially as oil temp in the sump is going to have a time lag behind the hottest parts of the engine and if i'd just climbed a serious hill.. so if the oil light comes on with this installed how do i know which is the problem..
