need to change the oil in the old work horse around the farm, its an 85 dodge ram 2500 with the 318 engine, engine has somewhere over 400000km's on it so we were told when we aquired it, (resets every 100k) it has 10w-30 dino in it right now, it leaks a small amount and also burns a small amount of oil, however working the truck hard in the bush today in very hot weather it seems to be blowing alot more smoke than usual....as well as the oil presure seems to be very slow to come up on hot starts. what grade of oil would work best? im thinking of using GTX 20w-50 to try for more oil presure and less burn? make sense?
