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.
The current XL label includes preventive anti-gel support. Cold-flow results depend on the base fuel and treatment conditions; do not assume a guaranteed low-temperature limit or use it to restore fuel that has already gelled. Choose a suitable cold-weather treatment for the conditions and follow its label. XL may be mixed with other Opti-Lube diesel fuel additives as stated on the label; follow each product’s directions.
Refilling and dispensing
The included refill bottles are supplied empty. Their capacities do not add to the quantity of XL in this kit. Refill from the bulk container, measure the required dose and keep all containers clearly labeled and securely closed.
Read the product label and Safety Data Sheet for complete handling, storage and safety precautions. Continue normal fuel-filter and water-separator maintenance.
