Excellent Oil
Castor oil is still the standard by which all other petroleum and synthetic oils are judged. I've used 927 in every type of two-stroke application possible and at every mix ratio possible. By far, it is my favorite oil and the smell is classic two stroke. If castor isn't your thing, check out SuperM - I've gone through a few dozen gallons of that stuff too, excellent oil.
