What to do with old (but never used) motor oil??
me. My father-in-law had the largest shop I have ever seen. He is no
longer with us and after looking thru his shop I found a ton (and by a
ton, I mean 50-70 CASES) of motor oil. All of it is new and never been
opened. The problem is that it is from the late 1980's. Some of the
quarts have a stamp from 1987. The boxes are dirty and some even have
"dirt dobbers" on them. He had all types, Pennzoil, Q-State, Valveline,
you name it, he has it. SAE 35, 40, 10W-30, it is crazy. Is it still
useable? Could it still be used? I thought that you guys who have some
nice classic and muscle machine would know. Could you use it those type
of engines? Is there anything to the rumor that with the harder engines
you guys need the older oil because the newer stuff does not protect
your engine as well? What the Hades do I do with it?
Any advice would be helpful.
