## Overview

Royal Purple Max Boost Octane Booster is a 16 oz high-performance fuel additive designed to raise gasoline octane by up to 30 points, reduce engine knock, and protect valve seats without lead additives.

## 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.
