I understand that. I've been around long enough to assume like anything else there is probably a decent amount of snake oil out there and I was looking for specifics on what additives if any people are using and if they are happy with the results. I'm assuming the more reputable companies like Redline, AMSoil, etc... are good but, some of the others I've never heard of.
