Re: How old is too old?
It would totally depend on where and how it was stored. If it was stored indoors, under climate controled conditions,it should be A-1 primo,"nothin wrong with that grade". If it was stored on the back porch floor,and the bottom of the box stayed there when you picked it up, I would have the same question. And here is how to answer it;<br />Get a coffee filter, support it in a funnel,and drain pan, and pour about 4 ounces or so into it.<br />Let it drain thru the filter until it's gone (probably overnight). If you find any specs, or gelly-like nodules on that filter, it's shot.<br />If not, not much else happens to dry-stored, sealed oil.<br />At least, that is how I would decide. But I am no oil guru iether. Still, I wouldn't hesitate to use it if it passes that test.<br />Just thot of something else tho..Make sure it has "TC-W3" on the label.
