Treatment and use
Measure XL for the amount of diesel being treated. The standard label rate is 1 US fl oz per 10 US gallons. For maximum lubricity and deposit control, use the premium label rate of ¼ US fl oz per gallon or more. For example, 20 gallons requires 2 fl oz at the standard rate or 5 fl oz at the listed premium rate. All volumes are US measures.
XL does not contain anti-gel and does not provide cold-weather anti-gel protection. For preventive cold-weather protection, choose XPD All-Season or Winter as appropriate for the conditions and follow the selected product's label. Preventive anti-gel must be added before fuel gels. XL may be mixed with other Opti-Lube diesel fuel additives as stated on the label; follow each product’s directions.
The Opti-Box is a bottle storage case. Keep bottles capped and secure them before transporting the case.
Read the product label and Safety Data Sheet for complete handling, storage and safety precautions. Continue normal fuel-filter and water-separator maintenance.
