Update #2
Dropped the old winter oil and finally got to pour in the 5 Litres of Esso XD-3 15w-40 last night, along with a new to me baldwin filter. Although temps have not been very typical of summer weather as of yet, intial findings are that I have higher oil pressure at startup and hot idle pressure seems better as well! I will get a chance to do some trailering this upcoming weekend so I will post back in a week or two and if all goes well will post a UOA in a few months time. All indications so far point to the truck
(year 2000, Dodge Ram with 49,000 Km) liking this oil so far. Any others of us Canucks added this oil to their ever growing list? would like to hear comments or experiences.
