Favorite gas additives

Torco is the best fuel additive you can get. It actually works exactly as advertised unlike those other cheap options in part stores that don't work. I used to run it all the time in my '05 Legacy GT. Car was originally tuned on a full tank of 100 octane. Since that was a very expensive fuel to run daily I decide to run Torco all the time. I add Torco filled up with 93octane and ran the car on the 100octane map and it ran perfectly with 0 knock. I was actually able to get a bit more aggressive with the timing map when I ran it.

I'm in the same boat as a lot of people.You have modified your car and are running a higher octaine map.Can not buy high octane fuel at pumps.Have bought VP race gas from stealer in town.$13.00 a gallon.I can get cheaper online but shipping makes it a wash.
So the much debated fuel additives.Have tried Lucas,Boostane,NOS,Royal Purple and was using Torco.
Started useing Race gas additive last summer.Liked the power,seemed to run smoother.The stuff is not cheap though.I would like to know who else is running race gas additive.
I like Race Gas and Torco.A lot of the other additives are junk.
