We used to use this two part oil. It was green on top and orange on the bottom. you had to shake it to mix it up. It was basically just 2 different weights of oil. The theory was one was for when the motor was cool and one for when it was warmed up good, much like your car oil. I cannot remember who it was that made it but I still have a little left, I think it was Rev-Tech or Trinity, but not positive. We did some tests at the track and at the time it cut 1 to 2 tenths off your lap times. I think they were called Rev-tech drops will have to look when I get home and see if I can read any of the label. But that is what I been using and so far so good. One drop last quite a while.
