All I am really saying is your "experiment" is not controlled tightly enough to determine whether your additive is making a difference. You are relying on a statistically significant difference that may not manifest because your variables are larger than the potential change.

But, no bold claims that we need to prove or disprove. Just people saying hey, its cheap, looks like a lot of people have tried with different levels of success since at least 2008, so that it seems to be low risk in relation to products people may be spending more money on anyway, which also have a small or non-existent body of evidence for thier claims.
Here is where I disagree. 2% to 5% is a BIG difference for a 0.15% concentration of additive. Unfortunately 2% to 5% is still difficult to measure given your context.

I think the worse it can do is keep things running well, if you believe the reports from others on the internet from the last 6 years. Any MPG gain is bonus. And maybe, the MPG gain is because , over time, the lubricants and detergents are keeping things clean and smooth? Don't know, I hope to see.
Yes, it is common to market a product in such a manner. And I agree, I don't think you will be doing any harm to your vehicle.

This research reminds me of a group research project, with a goal of 'lets see what we find out ourselves', which may or may not pass the level of any particular scientific test protocal. But, we hope it is valuable none the less.

The more we are upfront with the fact that this is an open discussion, with a broad range of people and test or use methods, the more people will hopefully see that we are just trying to add to a body of evidence that already has a positive internet track record.

Someone trying it and saying it made his car run like crap is just as valuable as someone that said it now idles smoother, but no MPG gain. So who knows where this thread will go.

Later!
I appreciate your willingness to read and address differing opinions and trains of thought. Since your thread title invites "open discussion" I am glad to participate.
