Schaeffers is a super high quality product. Along with Amsoil, Petro Canada is another with very high quality products. I have been running schaeffers soyshield fuel additive for years and love it.

Yeah I've heard of a lot of guys running it. We used to put it in a lot of the farm tractors I worked on. Just depended on what the customer wanted to use. As far as I know, it's good oil!

I have heard nothing but GOOD about Schaeffer's oils. I wanted to run it in my 98 on the last change but funds didnt permit.
