synthetics are the real deal. You can actually pick up a few whp by using all synthetic fluids(engine oil, gear oil, tranny fluid) as it requires less power to get it to flow. For those tuneup in a can things, some of them have their uses but they are generally BS.
Synthetic oils are unlikely to give you any measureable performance increase. The viscosity of the oil is what matters, not whether it's synthetic or not. And even then, you're not going to notice the difference.
even with the same viscosity index synthetics flow faster, because of the lack of waxes and paraffin in it, if i remember correctly. I remember a test done where all the fluids of(i think it was a foxbody) were drained and replaced with redline synthetics, and it picked up 7 rwhp
It will not give you a measurable dyno increase, trust me. I dyno my car and I'd know if something made a difference.
You also need to look at the source of where you get your information, since most of the time the people publishing the info have something to gain/lose by posting the results. Make sure to only trust objective information, not info published by the manufacturer of a product, its competitor, or a magazine that gets advertizing revenue from them.
Those are a little different. I was mostly referring to oil additives.
They could certainly be beneficial, and aren't going to hurt anything.
It's not only the viscosity. We're also talking about friction, and synthetic = less friction. That's where the power increase comes from. Less friction = less heat, which means more heat-energy is being used to drive the engine.. which means more power. Of course, it isn't going to be more than a few percent, and I agree you aren't going to notice it in everyday driving.
If you replace all the lubrication fluids in your engine with better ones, it isn't much of a stretch..
Yeah, it will have less friction, it's just that if you ever dyno'd a car you'd see how the numbers vary on each run. You might see a 10rwhp fluctuation between each dyno run on the same dyno, same day, same temp, etc. The increase in power you get from synthetic won't be noticeable since the variations between dyno runs will mask the power increase you got from using synthetic. Trying to find a 2 hp difference in the dyno results when the readings may vary by 10 hp will be pretty tough.

Well I wasn't really referring to race-my-car kind of performance enhancing - poor choice of words... I guess I meant life-extending... good-for-your-everyday-vehicle kind of thing.
Someone explain gas = liquid to me. I guess I need that clue also. This better not be that "technically it is" horse manure either.

Nobody is saying that gases are liquids. It's just that both gases and liquids are fluids.
fluid
1 a : having particles that easily move and change their relative position without a separation of the mass and that easily yield to pressure : capable of flowing b : subject to change or movement <boundaries became fluid>
yes, there are some fuel additives which can actually weaken the integrity of the nylon sock over the pickup tube of your fuel pump, and should the pump suck that sock up when it breaks, you'll need to replace it.
Engine oil additives like ZMax have been proven to actually cause more bearing and component wear, the WTO had a suit against them.
