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).
-------------------------MORE INFORMATION Octane + E10 Fuels----------------------------. An octane number is a measure of gasoline's ability to resist pre-ignition, also known as knocking or pinging. Octane is a rating, similar to a ratio of measurement, not a substance chemical or product you can add to gas. When E10 gas phase-separates (high octane ethanol drops to the bottom of the tank with water), the upper tank layer octane typically drops 2.5 points. 2  E.G. 87 octane gas purchased now becomes sub-octane 84.5 gasoline.
