3oz per 1gal =40:1 and ive ran mine that way for many years and works great! 50:1 mix with premium gas. period. Only run leaner if you have a modified saw. (if you dont know it its modified, than it probably isnt). so always run 50:1!

40:1 with high quality 2-stroke oil mix would be fine. http://store.chainsawr.com/
With Stihl most Super models have a piston diameter that is 2 mm larger than the other version of the same model. The Super is still an AV otherwise as that stands for anti-vibration, which means that it usually has four shock mount buffers between the engine and handle

A STIHL 045 av is 75cc and the max recommended bar size for it is 32". However... If you have a 045 av Super then it would be 87cc and the max recommended bar length would be 36". So it depends if you have a SUPER or not. It is easy to tell as it will say SUPER on the top tag right below 045 av.
I have written in my Stihl 051 AV electronic Owner\'s manual that its horsepower is 5.8 hp at 7,000 rpm. I don\'t know if that is true for a Stihl 051 super. I have never heard of a Stihl 051 super.

The difference is in the motor size.The 034AV is 56.5cc (cubic centimeters) and the 034 Super is 61.5 cc (cubic centimeters). The 034 Super has a slightly larger motor, and therefore it presumably also has greater speed and power.
