No, no need to.

Oils today do just fine without any other additives.

+1 sounds like a scam to me. just buy a good synthetic and you'll be alot better off (amsoil, royal purple, mobil one).

I would use it in an old Detroit V8, but not a Hyundai I4. Think about it: If the wrong brand of filter can mess up your car, why put something in that may affect the viscosity and stuff. Only put in the recommended oil.

oh, okay its like "seafoam".
if you want to run it to clean your injectors, go for it. I used some seafoam on my carb'd bike and...err, umm it runs about the same, lol. but I will say that when I drained the tank, I didnt notice much in the way of "old gas particles"...maybe it helped that, maybe it didnt.

if you use dinosaur oil and dont change regularly...meh, give it a shot, probably wont hurt. if you use synthetic and change your oil on time, I wouldnt worry about it.
