I just received my new C4, was wanting to know should I use more oil to breakin the motor or just straight fuel? I use Byrons 25% and have their lube booster, should I go up to an 18% oil content?

I would use the fuel as is, but make sure you are nice and cool during the first 2 break in tanks. Then start to drive it and after several more tanks start to lead the motor out.
