Help WD 40 OIL might be bad

[ACTION JACKSON]

I bought a gallon of WD 40 from harbor freight.
The outer handle started to rust so I put the oil in a plastic jug that won't rust. JUG WAS CLEAN.
The next day I noticed a separation. at the bottom was a look like a thicker creamy substance while above was the normal clear wd40. My question is, is this normal & I'm wondering if harbor freight is stuffing the can with some kind of a filler to give the buyer less wd40 making us think we're getting a full gallon. This creamy substance isn't water & feels slick like oil.
I flush my carb out with wd40 on my gas boat. I also shook the jug to mix & it's separating again.
ANY HELP WILL BE APPRECIATED. THANKS.

Id throw it away,WD40 in a gallon can will attract moisture and grow bacteria over time

Sounds like that can may have been sitting in a damp warehouse for a while and absorbed some moisture. What you describe is when WD40 absorbs moisture. I pulled a green head apart last night and noticed a Vaseline like jelly in the cooling jacket. That was WD40 sprayed in there probably 10 years ago.
