Try Archoil, Archoil | The Latest Developments In Nano lubrication http://www.ebay.com/itm/Archoil-AR-S-Kit-for-Car-Truck-ATV-Treat-up-to-8-Quarts-Oil-336-Gallons-Any-Fuel-/140952452580?pt=Motors_Automotive_Tools&hash=item20d16bbde4&vxp=mtr#ht_1040wt_900
I put it in a 2010 Equinox (4 cylinder) only product that stopped detonation. Higher octane was a waste of money, other fuel additives useless. Expensive, but I did notice improvement in mpg, at current useage it would save me about $80.00 a year in gas. Eventually pays for itself. I used the fuel and oil treatment.

Archoil.....interesting product. But I doubt if it would correct an engine mechanical problem. Might be a "Band-Aid" approach, covering the underlying problem.
Excessive valve train, or engine knock (if it is) if far different than spark knock do to low octane or poorly blended gasoline, imo.
