Lucas Fuel Additive.
I buy it at a local Napa store and it's around $4 for a 5.25 ounce bottle. I like all of Lucas's products and use their oil additive too.

Don't use oil additives.
Your oil is literally a witches brew of different additives. Oil companies spend perhaps millions of dollars in R&D. When you add something to your oil, you will upset whatever chemical balance there is within your oil. It just isn't a good idea.
If you're using an oil additive with PTFE(teflon), stop NOW. PTFE is a solid, and it has absolutely no business being in your engine's crankcase. Your oil filter is designed to remove solids, and it does exactly that. Your oil filter quickly collects all the PTFE particles it can.
Instead of screwing with your oil, focus your concentration on the filtration systems. Afterall, they are your first line of defense. It does not matter which oil you use, or what you put in your oil, if there are solid particles in it. This will much more for the life of your engine than any specific oil or additive.
