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).
What is octane rating? Octane rating is the measure of a fuel's ability to resist knocking or pinging during combustion, caused by the air/fuel mixture detonating prematurely in the engine. In the U.S., unleaded gasoline typically has octane ratings of 87 (regular), 88â90 (midgrade), and 91â94 (premium).
