Been using this fuel injector cleaner off and on for a while.

Usually I'd add an ounce every other tank (about 30-35 liters).
I noticed on the fills that I DID NOT use this cleaner the idle was poor again, *slightly* longer crank times, and an overall harshness to the engine's performance. Continuing this trend lead to terribly poor performance but nothing abnormal compared to other Focuses of this generation. Focuses in general are known for having a lack of refinement compared to, say Honda.
Since there's measurements on the bottle of .5oz 1.0oz and 1.5oz, I decided to put in .5oz every tank to keep performance consistent.
As a result the performance has been amazing. Every fill with it the car runs amazingly smooth and more powerful than it's every been since I purchased it in 2013. I am convinced that every other Focus out there runs worse than my car (it's that good).
Oh, I forgot to mention I also run regular 87 grade fuel (what's been spec'd for per the manual).
In terms of the math per dose, it works out to 32 tanks of fuel I can treat (473ml=16oz/.5=32) at roughly $7.00 per bottle (when I get them on sale), that works out to roughly an additional $0.22 per treatment...far cheaper than buying mid or prem grade fuels...especially here in Canadaland.
Any downsides to this small amount? am I hurting anything in the process?
thanks
