### ⭐⭐⭐⭐⭐ Less ping better performance
*by T***N on March 24, 2022*

Well its not cheep. But it really does what I need it to do. I have a 67 built triymp spitfire that can run on 101 but can only get pump gas. It keeps the pre igniton to a min . I use one can for 10 gall. The funnel is worth keeping for other additives

### ⭐⭐⭐⭐⭐ It works, at least for me
