Gasoila Gas Gauging Paste, Detects Water In Fuel, Gasoline, Diesel, Kerosene, Petroleum, 2.5 oz. Jar

says a paste but mine was like chocolate syrup

It works...you can see the fuel level clearly...you just have to wipe and reapply often. Beats using chalk.

Works well enough.

it is ok for a standby.when kolor kut paste arrived this product put away.gasoila would be better if it was not so sloppy.

Use this to test for jet fuel in oil water separators at our fuel farm. Works good.

Great product

Great product! Awesome quality!

Great stuff!

great

It doesn’t work as well with diesel fuel. Got it to sound the tanks on our fireboat.
