From my deceased father I have a few cases of this Pennzoil 30W that has always been in a climate controlled basement (65-75 degrees)
Earlier today I call Pennzoil, the rep tells me the oil pictured was in production from 1988-1996 and to not use it and he tells me > > > "our oil has a four-year shelf life". Maybe he stated that as to not be liable?
I stated it was always stored indoors, no freezing etc. The rep said > > > "the additive package drops out of it."
When I pour out some of the oil I see a dark residue at the bottom... if I shake it up, it's gone.
So, by shaking the bottles isn't that putting the additive package back into suspension and how does an additive package degrade from age?
Anyhow, I hate to toss it and would like to use it in the Lawnmower etc. but won't 'if' it will damage to an engine.
Your opinion is appreciated, thanks!
