I bought a pack of 6, I’m down to two….hehe....this is how I use it, take out all the spark plugs pour a bunch in each (you should have 2/3 left), put back spark plugs, put 1/3 in the oil and the rest in the fuel tank. Sit for 20-30 min, turn on the engine (will take a few turns) rev it, and drive the piss out of it.
If you have heavy carbon deposits and it shoots a think black smoke then you need to change the O2 sensors.
with a second bottle pour half into the intake
