I've had two additive type products work for me; one was a can of Bars leak for a heater core leak; the other was bars leak seal conditioner.
My sister was in college, and drove an AMC Madador (yep, sets the stage on how old we are today). The heator core leaked buckets! I did not have time that weekend to yank the heater core from the dash (back then you could do this without a dash removal), so I tried that rabbit pellet stuff. The pouring water went to a stream, a drip, and then dry. I was amazed it worked, and since there was no internet back then with forums screaming of folks saying the stuff clogs your radiator, I had no worries. She drove that ugly as sin car another year and a half, and it never leaked, nor overheated.
Move on to 2014, and a 2000 Ford Ranger 4x4 with a 3.0 I owned. It had 212K on its original engine; runs great, but the rear main seal leaked about a 2 inch puddle if it sat for two or more days. My buddy accross the street owns an old 63 Pontiac Bonneville. He told me he used bars leak seal conditioner in an oil change a year ago for the same situation I had. His stopped leaking from the rear main seal. I researched this stuff (now have this cool thing called internet with lots of forums), and read some good, mostly "snake oil" articles about the stuff.
I bought it anyhow, and low and behold, the rear seal stopped leaking. I gave that truck to my son (along with a 2005 F150). He uses the Ranger as his weekend 4x4 toy. He's since put on an additional 30K more miles on that truck, and no leaks. Every other oil change, he adds another bottle of it in.
However, with engine oil on my 2007, I don't prefer additives, but rather use an oil with the high mileage additives already blended in. If it developed a rear main seal leak, I'd most likely toss a bottle of the bars leak seal stuff in it though.
