Treatment and use
Measure the additive for the amount of diesel being treated and follow the directions on the container label. The warm-weather label lists 1–2 fl oz per 20 US gallons above 32°F (0°C). Boost! can be used at any temperature, including below 32°F (0°C). It does not provide cold-weather anti-gel protection. Use the higher listed rate for maximum cetane boost and quicker fuel-injection clean-up. The “up to” treatment capacity uses the lower listed rate; doubling the dose halves the amount of fuel treated.
Boost! helps clean injectors and provides added fuel-system lubrication. The label states a cetane increase of 7–9 points; results depend on the starting fuel and dose.
The Opti-Box is a bottle storage case. Keep bottles capped and secure them before transporting the case.
For safe handling, storage and precautions, read the product label and Safety Data Sheet before use.
