What types of fuel additives does everyone use? I haven't been using any but I was told that I need to, is this true?

Most guys use a mix of about 8 oz of Power Service and 8 oz of 2 stroke oil per tank. I've been using it since last fall and can't honestly say that I've seen any real improvements in performance or mileage. Other guys who religiously track their mileage have some proven numbers for increased mileage using this mixture.

Lots of guys use Stanadyne products. They are a little more expensive and a little harder to find and questionable if any different or better than Power Service.

This thread will likely get moved over the the "Fluid Discussion" area. There is numerous on-going threads about this topic.
