Some time ago there was a long thread about the relative benefits of using octane boosting additives with the usual debate about whether it was a good thing or not (I think the general consensus was that it wasn't)

There is another family of stuff that positions itself as a "fuel system cleaner" which is supposed to give you efficiency through cleaning things up (as well as burning off in huge amounts, I think)- I tried some a buddy gave me, and I have to say, while the stuff is in the tank, I could tell a BIG difference in pull. I'm about to fill up for the first time since, so I'll be curious to see if the difference is lasting.

Has anyone else tried it, and what kind would you recommend? (the stuff I got was called Max 44- I have no idea where you can buy it)

the on-the-shelf stuff is just usually more concentrated, but then you dilute it with 20 gallons of gas

Use it just before every or every other oil change.

was told that it cleans even better on an empty tank.
