In many people with tinnitus, the cause is not known. The ear is otherwise fine. What seems to happen is that signals are sent from the ear down the ear nerve to the hearing part of the brain. The brain interprets these signals as noise. It is not clear why these signals are sent from the ear.
Octane booster is  a product which is designed to rise the octane rating of the fuel. The main idea behind using boosters is to increase power and also vehicleâs efficiency in certain engines. These have anti knock additives which when added to fuel prevent the onset of knock (detonation or pre ignition).
There is a misconception in the world that high octane fuel will make your car go faster or run better. This isnot true. The octane rating only rates the fuelâs resistance to engine knocking. Knocking or pinging is a sound that an engine makes when the air-fuel mixture in the combustion chambers ignites too early.
