I have been running Shell Rotella in my last 3 Power wagons. Knock on wood but with 5W-40 I have never had the Hemi Tick with over half a million miles logged on all 3 trucks.
I worked in refineries decades ago with a fellow whose uncle was a chemical engineer. Maintenance work done included setting up cracker towers for catalyst renewal. Noted that some refinery companies utilized clay ball catalyst and the oil "jugs" used where motor oil was processed indicated no fewer than 4 company logos on the containers. The packaging plant from one refinery supplied four different brand names from the same source.
There were different catalysts used and one particular refinery used the clay ball catalysts I noted in the cracker towers which required replacement from time to time. The oil from that source had a dark appearance.
I asked my co worker one day about his uncle who was employed by different refineries who had experience in his profession if he ever indicated anything about the competing motor oil companies relative to oil types. He told me that Shell oil used chromium catalyst in the cracking process and some refineries used the clay ball catalyst type instead. His uncle had told him to buy a quart of Shell oil and one of a different brand he specified and to fill a glass of each brand to compare color. He told me the Shell oil was a see through light honey color and the other brand was a dark hue not transparent. I had used both oils and noted this years ago but never questioned it. His uncle had told him the clay catalyst oil had dissolved microscopic particles in it and the chromium type catalyst used by Shell had none.
His opinion as to the best motor oil made was that produced by Shell. At that point I started using Shell oil exclusively in my motorcycles and other vehicles. As time passed I noted the color of different oils and over fifty years later note that there are no more oils I have noted that are dark in color. Whether it is a better refinery oil cracking exclusive use of chromium cracking material or better filtration processes, I do not know but the oil brands I use now that are from different sources are all honey colored.
My use of one brand with a dark color pre Shell oil switch did not cause any engine problems in my experience. Never had an engine go "south" on me except one in an Argo which had extreme use decades ago.
Anyone I talk to tells me that Shell oil is a top grade lubricant motor oil and I do not disagree but synthetic oils have replaced petroleum oils in large part both in Canada and the USA. I use them exclusively in my vehicles and equipment. I have purchased fifty gallon drums of Shell oil for use along the way. I am now curious about lubricants and know the man who can answer any questions I may have on lubricants...it is the same fellow who counsels me on oil grade viscosity to use in my Dodge truck. Lockdown here precludes contact with him but I will see him in the near future and inquire.
Learning is a voyage not a harbor and things change either for better or worse. Technological strides affect everything, mostly for the better, but humanity in its devolution processes seems to be affected negatively in the moral sphere of existence by the Law of Entropy. Proof is everywhere!
