Has anyone ever heard of Pro Blend Engine Cool or Tranny Cool? It is an oil or tranny additive that supposably lowers oil and tranny temp up to 57 degrees. They also make it for radiators that lowers temps up to 28 degrees.
Just wondering if anyone has seen it or uses it or has used it or found out bad things about it.

 

Nobody has ever heard of these? That's what I was thinking.

 

i sure havent. im not too educated on the subject but 57 degrees seems like allot to me for an additive
