Amsoil PII am always a little apprehensive about performance claims on things you cannot physically see or test for. This product defies that... I decided to switch to Amsoil everything on our 2015 GMC Acadia and said what the heck I’ll try this out too. After using it once my 3-4 crank start ups went back to the factory fresh 1-1/2. Went on a family trip that usually uses 1-1/2 to 1-3/4 of a tank and this is where it got really good, went round trip on 1 tank!!! Highly recommended this, can’t say the frequency, but at least once a year. Good stuff!!!Bottom LineYes, I would recommend this to a friend.
