I am currently 74 years old and was introduced to the OPTI 2 product over 25 years ago when I purchased a 2 cycle outboard motor. I was skeptical of this one size fits all idea, so I used it in all the older 2 cycle engines I had before I used it in my new outboard. Needless to say, I am still running it in a 28 year old Echo weed whip to this day. The greatest feature is, if you are like me, you have an assortment of 2 cycle engines your use and they pretty much have their own default mixing ratios. With OPTI 2, you make up one batch of 2 cycle fuel and it works well in each engine. For example, my grandson paid us a visit this last summer and helped us with the chores around the yard. My peace of mind was that I knew he would not damage any of our weed whips, chain saws, leaf blowers, or 2 cycle ATV’s with the wrong mixture of fuel. It is the greatest way to take proper care of your 2 cycle mixture needs.
