Oil....
Who ever did the job for you, probably sent you a bottle of a special formulation of an injector oil. If not, then run with your regular injector oil and add about 10 ounces of your injector oil with 5 gallons of gas. SO, your running your injector oil and your premix in the tank, that should make your fuel/oil ratio about 38/1.
The reason you use more oil is to help seat in your new rings. Vary the throttle a lot, never stay in one place often and avoid WOT for the time your breaking in the engine. You can wind it up to WOT, but only for a couple seconds.........then, after you've gone through that fuel, just fill your tank with regular fuel and go for it.............you should be fine by then.:cheers:
