Are you talking about Uncle Scottys cocktail? If so either use the search function here, or on for it.

That sounds like a horrible idea. I don't think you should ever add oil to your gas tank. Subaru WRX/STis run bad enough when people (for whatever reason) put regular 87 octane in the tank. Stick with premium unleaded and call it a day.

The mix you might be referring to could be some kind of mixture of race gas and premium unleaded - some cars might be able to get away with running slightly higher octane gas, but Subarus are picky and must be specifically tuned for such things.

Any car needs to be tuned for higher octane to reap the true benefits.And if they are just using an "octane booster" they are just wasting money.

just remember, "points" on those cans are most of teh time TENTHS of octane. "5 points!" means .5 octane.

Of course, most of em are even over spec'd at that. Also they're not always clean burning. Also, they don't do shit anyway unless your car is tuned to use the higher effective octane.

If you put in 14 gallons of 92 and want 93 out of, say, a 12 oz can? The shit in there better be 242 octane. That's 1 octane boost. Most of the shit in the cans ain't 242 octane, I assure you. If you want regular gas to be like race gas from a can (say 14 gallons of 93 into 100 octane from a 12oz can), it'd have to be an eye poppingly ridiculous 1146 octane.
