The 2 or 3 brands of octane booster that really work are no substitute for real high octane race gas available from tracks and some race shops.
Their real value is for 94 tuned cars in areas where 94 is not sold or when it is out of stock in your locality , or when high octane race gas is unavailable to mix in lower octane fuel.
I've used TORCO in my FRS since 2012, stock and boosted, when I got a bad batch of 94 that showed knock, in travel through areas with no 94, or at Mosport , Cayuga etc. when the pumps are closed. The small amount (of TORCO) required to bring it up to 94 makes it economical.
In those conditions of over 7 years use, no problems were caused. All it did was leave an orange colour to the plugs and cat, and the cat did not plug up.
I am assuming the new competitors to Torco are similar.
