Compatible with a wide range of engines including turbocharged and nitrous-injected, it enhances power and fuel economy while protecting catalytic converters and oxygen sensors. Ideal for professional-grade performance tuning and racing applications. ## Description Royal Purple Max-Boost - 16 fl oz Can is a high-performance octane booster with fuel treatment that increases gasoline octane, reduces emissions, and enhances engine performance while stabilizing fuel. Max-Boost is formulated with MMT, which delivers the best octane enhancement to help eliminate engine-damaging detonation, pre-ignition, and pinging or knocking from low octane gasoline. Max-Boost is formulated for engines equipped with carburetors, port fuel injection and direct injection, as well as turbocharged, supercharged and nitrous-injected engines. Safe for use in leaded and unleaded gasoline's, and alternate fuels like gasohol, reformulated gasoline, and all ethanol blends. Max-Boost is safe for oxygen sensors and catalytic converters. Performance engine oils contain higher levels of phosphorus as an anti-wear additive, which can accumulate in catalytic converters and reduce their effectiveness. Max-Boost protects against phosphorus poisoning of catalytic converters.

Attenzione che essendo un booster a base di MMT, pur essendo un ottimo innalzatore del numero di ottano, può lasciare depositi di ossido di manganese, sporcando candele, valvole, catalizzatore e sonda lambda. Gli additivi detergenti aiutano tuttavia a pulire gli iniettori, e l'effetto antidetonazione in proporzione alla quantità di prodotto è sensibilmente superiore a molti altri prodotti. E' quindi indicato all'utilizzo su autovetture più a indirizzo sportivo che utilitarie modificate (quindi senza catalizzatore e utilizzate saltuariamente) e magari da usare solo in occasioni specifiche ove si prevede di tirare l'auto e si vuole ridurre al minimo il rischio di detonazione anticipata, oppure come soluzione di emergenza qualora ci si dovesse trovare in luoghi sprovvisti di distributore con 100 ottani. Ne sconsiglierei l'utilizzo continuativo. ## Frequently Bought Together - Royal Purple Max Boost Octane Booster - 16 oz. - Royal Purple 18000 Max Atomizer Fuel Injector Cleaner, 6 fl. oz. - Royal Purple Max-Clean Fuel System Cleaner and Stabilizer 11722 20 Ounce --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/224763262-royal-purple-max-boost-octane-booster-16-oz](https://www.desertcart.co.uk/products/224763262-royal-purple-max-boost-octane-booster-16-oz) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-24*
