I have not tried the 2 Stroke Oil as of yet. I have used the Ford Cetane Booster and found it helps some with throttle response and the seat of the pants dyno.
I recently tried the Red Line Diesel Fuel Catalyst and it has a better feel than the Ford Booster. I had some in and was low on fuel and added only $10 at $2.89 and I could tell it was not performing as well. Filled it up with 1/2 a bottle and it was back to the Wow factor.
Runs about $7 to $9 depending where you can find it. My local O'Reilly Auto Parts.
