Octane boosters from companies such as Lucas Oil and Torco are good options to avoid potentially damaging sensors.

It’s worth noting that unleaded octane boosters can be “healthier” for your car, since leaded fuel has a tendency to affect or even harm oxygen sensors. Products will vary on the blend of these ingredients, but these are normally the base for most octane boosters. They are typically a blend of tetraethyl lead, alcohols (including ethanol), traces of methylpropyl, manganese, toluene, and ethers. When you’re shopping for octane boosters, you’ll notice the ingredients used in most of the products are fairly straightforward. This results in a higher compression ratio and better vehicle performance. Generally, as octane ratings increase, pre-ignition becomes more difficult. Octane boosters are a fuel enhancement product by increasing the octane rating of the fuel, enhancing a vehicle’s performance. Octane boosters are part of the “fuel additive” category, which typically includes fuel enhancement and fuel stabilization products. Safe for oxygen sensors and catalytic converters, this octane booster is safe for use in leaded and unleaded gasoline, along with alternative fuels such as gasohol, reformulated gasoline, and all ethanol blends.

It’s formulated to work on engines equipped with carburetors, port fuel injection, direct injection, turbocharged, supercharged, and even nitrous-injected engines. It also serves the purpose of reducing power loss caused by knock-retard in computer-controlled vehicles.Īvailable in a 16-ounce can, Max Boost is formulated with MMT, which delivers the best octane enhancement to help eliminate engine detonation, pre-ignition, and pinging or knocking caused by low-octane gasoline. Max Boost replaces lead additives for the protection of non-hardened valve seats, allowing it to restore power and fuel economy while cleaning deposits from fuel injectors. This racing formula raises octane rating up to 30 points or three numbers, so it’s worth mentioning that it’s not street legal. Our top-performing octane booster is the Royal Purple Max Boost, designed to increase horsepower and stabilize fuel while reducing knocking and pinging.
