Where does the 2 stroke oil go in a 1995 Suzuki - RM 80?

You mix 2 stroke oil with your gas, slosh the can lightly to mix it good, then pour it in your gas tank. The proper ratio will depend on what type of oil you will be using for your premix. The oil base stock is either petroleum, semi-synthetic or synthetic oil and is mixed with gas at a ratio ranging from 16:1 (petroleum) to as high as 100:1 (synthetic). My 2 stroke I have is a 2001 Kawasaki KDX200 that I run Yamalube 2R at 36:1 with no problems. Although synthetics say you can mix them at 100:1 I would not, that seems way too lean to me.
