Octanium Unleaded is formulated to provide an octane boost – up to 7 numbers (70 points), increasing horsepower. It is safe for use in cars and trucks with both catalytic converters and 02 sensors. Octanium Unleaded eliminates knocking and pinging, cleans fuel injectors, eliminates gum and varnish build up, and improves throttle response and acceleration. 32oz treats up to 10 gallons. (38 liters) If you use VP Octanium Unleaded octane booster in vehicles with emission control devices (ECD), dosage should be limited to 2.6 ounces per 10 gallons of gasoline. Non-ECD vehicles can utilize up to 5.3 ounces per 10 gallons of gasoline for long-term use, or 32 ounces per 10 gallons of fuel for short-term use. However, this will require more frequent maintenance to prevent damage or coating to engine parts.
