Wait up guys, all solvent containers in laboratories and all of the red
plastic gas cans are made of linear polypropylene, ethylene or a copolymer
of both. Polyethylene is more resistant to chlorinated solvents and ethers
while polypropylene has more resistance to acids, bases and alcohols. The
charts list resistance of PP to gasoline as good at 20°C and fair at 50°C.
Hope this helps...
