Amsoil has conducted 10's if not 100's of thousands of tests over the past 55+ years but you still have to WANT to push the envelope!  AMSOIL is founded on a jet fighter pilot's dreams, aspirations and mentality to be the best and beat the biggest companies.  His name was Lt. Col. A.J Amatuzio.  

Tests includes but not limited to: field studies from fleets of taxi cabs, trucks to wind turbines, comparative test, dyno testing (they have many dynos), head-to-head truck test, and 1000's testimonials.   That's why you pay for what you get.   They have so much info they added a blog site, plus the YouTube channel.
