For injector- and carb engines. using low octane number gasoline in highly forced engines leads to a engine power decrease ( up to 30%) and engines lifetime also decreases. Detonation occurs and "smoldering ignition" ( engine doesn't stop right after ignition has been switched off). As a result engine parts will damage heavily. piston rings may break , engine resource decreases 2-2,5 times.
especially recommended on to use this additive with four-valve gas distribution system American, European and Japan cars , also also to a turbo engines.
use: pour to fuel tank right after previously mentioned negative events have occured. For regular use pour into the tank before filling up fuel tank, then refuel. packing intended to 40-60 litre fuel.
doesn't damage catalyst, turbochargers neither oxygen sensors.
