Is JD  antifreeze worth the extra money? The JD jug talks of low silicate and anticavitation.   JD is green antifreeze.   I bought  Peak antifreeze.  Both are ethylene glycol,  both are suitable for Aluminum radiators. 

JD  is more than 2X  as much but is there anything to be gained by the higher cost?  

Peak is 5 year  150,000 mi.   Is peak really any better than store brand?  2 yr 50,000 mile?  or would 1 dollar worth of rust inhibitor make them equal? 

I would buy distilled water at 88cents/gallon if it was worth the trouble.   I would love facts instead of opinion and I'm not sure I know where to get facts.
