any of you using acetone in your fuel?

I don't touch additives. the TSB's as per manufacturers even say not to use them... use of most can and will void the warranty. (assuming your fuel gets tested if it's a major "failure")

Go buy your acetone. I can tell you the only reason your mileage has improved is because subconsciously you are more aware of consumption and are driving accordingly. In that ONE regard, it works.

I agree with this, there was the moth ball theory about a week or so ago.

I don't get it, most of these additives end up costing more money in the long run.

Fuel systems should not be jacked with.

As for racing fuels, those fuel systems are designed for it.
