Alrighty, firstly some history:

I have never met this person whom supplied this product, nor am I in any way affiliated with the manufacturer in any way.
Roil Diary:
26/3
Roil arrived by mail, had heaps of product endorsing paperwork with it, to which I promptly put in a pile to forget about, sorry but I am after facts of my own.
After stuffing around asking how much to put it because I am a noob, I added 300 mL into a semi-hot motor (been sitting after driving 6 kms home for about 3 hours)
Drove along the highway doing the limits 141 km’s, no noticeable difference, not giving it any time to either, was raining and hit heavy traffic going north from Brisbane.
27/3
“Seemed” to start faster but then again it might be the placebo affect, also added 100mL to my power steering fluid.
Drove home along highway 143 km’s, no noticeable difference, gave it a bit getting onto the highway too.
Total Kms since adding: 287
28/3
Time to give it a bit I go through the gateway toll booths a lot and have roughly guesstimated my speed at certain points and today I got off the mark well and got to the first bump going up the bridge from the gates and hit my markers at around the same time, so no noticeable difference yet.
Did notice that my power steering used to make this awful groaning noise, well not awful, but anyway it made this noise when I was standing still and moving the wheel, and this sound has gone now, so happy with that.

29/3
Road was a bit wet this morning on the way to work, and this road I know very well and did notice that the boost was punching in at around 2k to 2.5k rpm when it used to punch in between 2.5k to 3k rpm. Sweet!

No other differences but the turbo and power steering noise gone noticed.

1/4
Went on weekly cruise and told about the turbo to which everyone had a good laugh and said it was probably my imagination, but I stand by my finding, and tested it thoroughly tonight, yeap defiantly between 1mm before 2k and 2.5k rpm boost punches in.

Again went out cruising and watched the boost gauge and yes defiantly punches in where I am guesstimating it is.

4/4
Did my race to the marker from the toll gates again and noticed that when I hit it I am going about ~10kms faster, but then again I might have got a better start, not too much wheel spin that time, so I am not attributing that to roil.

So basically I own a totally stock car except for the mags so I did not think I would see much difference whatsoever and basically you can all laugh and tell me I am dreaming, but I did notice a difference in the turbo boost time, which I like because I hate lag.
I took the old owner, which I am good mates with and asked him if he saw any difference, before telling him anything. After he had a couple of trips around the block, he thought that the turbo was coming on sooner, not as much as I guessed, but he defiantly said it was coming on sooner, not by much though. He attributed it to a pod, when he asked I told him about roil, and showed him the bottle to which he looked at it and said, “hmmmm well I thought all these did nothing, hmmmm”
I am very interested in what results other people had, especially in a car that has more boost, bigger turbo, bigger everything
Personally I do not think I will be buying this product for the simple fact is other than long term benefits (which are unknown at this time) there is little point in spending the money to get a little less lag, I am more interested in putting it away for an EBC or a 3inch exhaust turbo back.
Anyway that is my independent report. I was a sceptic, thinking that I probably would not see any difference so I was very surprised to see it had some effect!
Today 7/4 I am putting in a highflow filter which I have been wanting to put in but did not want to put it in mid-testing.
All results were measured by the seat of my pants by myself in my own car.
