Not only are testers against it, so are companies, Amsoil, Valvoline, etc.

Here is another quote from a chemical engineer-
"Increased Standard Additives, (More Is Not Necessarily Better)

Though some additives may not contain anything harmful to your engine, and even some things that could be beneficial, most experts still recommend that you avoid their use. The reason for this is that your oil, as purchased from one of the major oil companies, already contains a very extensive additive package.
This package is made up of numerous, specific additive components, blended to achieve a specific formula that will meet the requirements of your engine. Usually, at least several of these additives will be synergistic. That is, they react mutually, in groups of two or more, to create an effect that none of them could attain individually. Changing or adding to this formula can upset the balance and negate the protective effect the formula was meant to achieve, even if you are only adding more of something that was already included in the initial package.
If it helps, try to think of your oil like a cake recipe. Just because the original recipe calls for two eggs (which makes for a very moist and tasty cake), do you think adding four more eggs is going to make the cake better? Of course not. You're going to upset the carefully calculated
balance of ingredients and magnify the effect the eggs have on the recipe to the point that it ruins the entire cake. Adding more of a specific additive already contained in your oil is likely to produce similar results.
This information should also be taken into account when adding to the oil already in your bike or when mixing oils for any reason, such as synthetic with petroleum. In these cases, always make sure the oils you are putting together have the same rating (SA, SE, SC, etc.). This tells you their additive packages are basically the same, or at least compatible, and are less likely to upset the balance or counteract each other. "


From a Quaker State Engineer-

"The potential zinc downside is that in theory, an engine with blow-by could accumulate zinc deposits in the combustion chamber, potentially becoming a detonation magnet."

Now as we all know additives are high in zinc content. This could be good, for a engine in brand new condition and a flat tappet cam. Not our XJ's though.

Just so you know, rednekwizard, the quote from a "chemical engineer" was actually from Fred Rau, a motorcycle journalist that probably doesn't even have a degree in Journalism because he started writing back in the late 60's. I question the validity of his other "intelligent people" quotes, I think they are just opinions, not facts... probably not from factual people either... just roll with it.

And to the OP, it was a fluke if you haven't guessed with all the other stuff happening here. Unless you put seafoam in the antifreeze that is.
