Marvel Mystery Oil (gas additive) make your engine knock?1
My gf got me this stuff called Marvel Mystery Oil (some stuff in a red bottle you can get just about anywhere that sells oil), it's this oil/gas additive incase you didn't know, I added 8 oz of it to about 10 gallons of gas (I use Sunoco 93 octane) and my engine seems to be knocking a bit! No CEL, but I'm not putting this stuff in there ever again. Has anyone else used it and had problems? Or good results maybe?

Your engine shouldn't be knocking at all unless you've done a knock sensor bypass. Even if your knock sensor is dead, the car would go into "safe" mode and not knock unless you bypassed the sensor with a resistor.
I know of the additive you're talking about, I've never seen it for fuel though, I thought it was just an oil additive... hence the name.

Also, not ALL additives are bad. I like Zmax and have had good experiences with it. I've used it in all my cars and no problems so far.
There was a street once where they were repaving it, so they strip the old pavement off first. My mom drove her car over a manhole cover that now sat higher than before due to the missing asphalt and it hit her oil pan. She spilled out all her oil and didn't even notice. She made it home (about 5 miles) with no problems or noises. She only told me that her oil light had come on. I went to check and after some checking, saw that she had gouged a nice hole in the oil pan and made it home with zero oil. I replaced the oil pan, refilled the car with oil and Zmax and started it, no problems.
I really think that if it weren't for Zmax, the car would have exhibited some sort of problem other than the oil light.

But we're talking about opinions, aren't we.... or are we?
http://www.ftc.gov/opa/2001/02/zmax1.htm
The agency alleges that enhanced performance claims for the product are unsubstantiated, that tests cited to support performance claims actually demonstrated that motor oil treated with zMax produced more than twice as much bearing corrosion than motor oil alone, and that the three different products - an engine additive, a fuel line additive and a transmission additive - were all actually tinted mineral oil.

Additives are crap.

Or you can go by this...
Bardahl, Rislone and Marvel Mystery Oil, etc... All of these products will strip sludge and deposits out and clean up your engine, particularly if it is an older, abused one. The problem is, unless you have some way of determining just how much is needed to remove your deposits without going any further, such solvents also can strip away the boundary lubrication layer provided by your oil. Overuse of solvents is an easy trap to fall into, and one which can promote harmful metal-to-metal contact within your engine.
I know you're some kind of engine expert and can measure engine crud to the 1/1000th of an inch, but the rest of us shouldn't be using these bottles of cra.....I mean 'additives' in our cars.
