Review on Enhance Your Engine'S Performance With Rislone Hy-Per Lube HPL201 - 32 Oz,1 Quart by Roberto Nastanovich

I will say that this stuff is at least somewhat effective and because of that it does represent at least a marginal value for the money spent. Archoil 9100 or what we that scam is called costs 5x more and did absolutely NOTHING when I tried it out.This product sells fo $7-8 everyday at W@1mar+. These Walmart vendors are currently asking almost double.This is a good but specialized product most folks will never need. I wanted to see if it could quiet down some of the NVH from a ford 7.3 powerstroke. Engine sounds like a box of hammers in a paint shaker. It did a little bit, maybe, but I think I’d rather spend $$$ on "better” oil. It’s a 15qt oil system so 2 bottles may have done more but I wasn’t gonna drop more than $9 on an experiment plus $18 extra bucks for an additive more than pays for the extra cost of full synthetic for my application.
