Sta-Bil Marine 360 color?

[jonnied1]

I bought a new bottle of Sta-Bil Marine 360 the other day and once I got it home, I noticed it was Purple - not the normal Blue color.
Did I get an old bottle or did they change something?

Nothing has changed from what I know on formula. Mine are all the dark blue. You might have gotten a bottle that was at the beginning of the line on a new die bottle and got a heavier dose than normal. I wouldn't worry about it.

I had an old bottle (sat on a shelf for a couple years after opening) turn darker over time. It smelled terrible. I chucked it.

I think the label says use within one year of opening.

Went and bought a new bottle at Walley Mart. Used the other bottle to start a fire in my fire-pit.
Found out it was manufactured in 2015 from the code on the bottle. Will not be buying from Auto-Zone any more.
