I played with some old lucas oil stabilizer I've had laying around for a few years. I added to castrol 30HD oil at about a 10% ratio in a used oil analysis sample container. My curiosity was about the aeration effect it has and if temperature played a big part. In Bob's demonstration, which was with gear oil I believe at room temp, it frothed up and turned milky white.
So I heated up the sample in the used oil analysis container, placed in a pot of water on the stove at roughly 170-190F. Wife giving me the
look
Point was to see if the sample would hold air bubbles like it does when cold. I figure the oil temp had to be at least 160F, flowed like water in the container, shook the heck out of it and there were still miniscule air bubbles in it, but not much worse if at all than the virgin 30HD oil. When shaking both at room temp, 65F, the oil with lucas held much larger air bubbles than the virgin oil. Overall, the virgin oil held very very little bubbles both times, and would be unnoticed unless specifically looking for it. The one with lucas held larger air bubbles, which was more recognizable at 160F but still would be unrecognizable unless specifically looking for it. At room temp though, it is very noticeable.
Not real scientific, but I kind of get the impression that the lucas isn't as bad as some make it out to be. Maybe a higher % mix of it would look different. This was also with engine oil, not gear oil like in Bob's demonstration.
In addition, I stuck both samples outside overnight at 5F average temp. Next morning, the virgin 30HD oil was practically solid in the used oil analysis container. I had it sitting upside down on the kitchen counter at 65F for at least a minute, did not move at all. The sample with the lucas flowed. I guess lucas oil stabilizer lowers the pour point or increased low temp flowability, because that's what I observed?
