Oil Additives

[Dead Eye]

I'm slowly coming round to the idea if this. It's not so much that I doubted their claims as whether I was prepared to fork out the money to verify them

A quick query; how much do you use? Had a quick look on the website and a flick through this thread but couldn't find anything (but I am blind to the obvious sometimes...). Reason I ask is that I would do both the car and bike.

I noted that the 125ml was for cars up to 1800cc and bikes up to 800cc but was curious as to exactly how far it gets you.
