Again, my mileage and yours may differ and it's my choice, not yours. Don't much care if you urinate in your engine, only you and your engine knows...
Stuff works for me and there is plenty of scientific evidence as to the cleansing properties of nano-borate, of which Archoil AR5000 additive is comprised of.
Besides if Jay Leno says it's good, it has to be. After all, Jay is a gearhead, rich gearhead.
Not sure if it's a feel good thing or not. All I know is my engines are very clean inside but then I change the lube oil regularly and I don't use cheap lubricants anyway. You usually get what you pay for and that applies to most things in life (except marriage).
