I've ran this 2 cycle in my Yamaha CV80 since I got it with 300 miles. Recently the oil line popped off.. like about every other line on the darn thing.. and had to borrow some from a shop along the way. I want to say it was Motul ashless but not certain. The scoot stunk with whatever it was and smoked to! Finally ran through it and got back to the Pennzoil but there a drop or two that's still in there. Guess I haven't been around 2 cycles enough to play with different oils.. but I'm going to stick with this Pennzoil!
