The gasoline paste is a light sky blue paste that turns a darker blue when immersed in gasoline, diesel, kerosene, naphtha, #2 heating oil, light crude oil, jet fuel, plant oils, and numerous petrochemicals. It has a thick, toothpaste-like consistency and is packaged in a 4 oz. /113g. Net Wt. jar.
Spread a smooth, even coat of the product on the bob or gauging device where you expect the air/product interface to be located. Once entering the product, leave immersed for approximately five to ten seconds and the paste will turn a dark blue. (Please note that some heavier products may require a longer immersion time.) When reading the results, note a straight, sharp demarcation on the gauging device, light blue above/dark blue below.
Note: If the gasoline paste separates over time, stir to remix to its original light sky blue color with a thick, toothpaste-like consistency before use.
Keep the caps tight. Store between 45 – 85°F /7 -29 °C
