Thought you would be interested in this. Berryman still recommends adding to cold oil. It can be added repeatedly without changing oil as long as you let oil come back to cold temperatures.
From Berryman:
“Yes, performing this treatment can address a sticking oil control ring; however, it may take more than one application, depending on the severity of the buildup and the design of engine. I would recommend doing the following…
Before anything else, put a drop of oil on a few different kinds of uncoated paper—computer paper, newsprint, etc. That will be your baseline color. Doing so while the oil is hot will help in comparing apples to apples. Then perform the service as described below.
The colder your engine starts out, the better because this lengthens the time the chemical is in the system. Once the oil has come up to operating temperature, all the solvents in the B-12 will have evaporated and you will be left only with your original oil plus any deposits it removed. At that point, put a drop of oil next to the original drops and see how they compare. If there was cleaning to be done, then you will see a difference in color.
If you do not have a way to visually confirm a benefit, i.e. less blue smoke out of the muffler, for instance, then you may want to repeat the treatment a time or two. Once the engine cools down, you can perform a repeat application and compare drops again. When the color of the drops stops changing, then you know you’ve done all you can do in the crankcase. The key with follow-ups is to let the engine return to ambient temperature each time. You never want to try to put B-12 into a hot crankcase.
Hope that helps. Feel free to call, text, or reply if you have any additional questions.
