Shelf life of gear lube?

[therealjoeblow]

Hi,

I have 2 one litre bottles of Quicksilver High Performance Gear Lube (lower end lube) that my dad bought and stored before he passed away. They are about 10 years old, never been opened, the foil seals on the bottles are still intact, and they have been stored year-round in the boathouse, so would have gone through seasonal temp swings of +35 to -35 degrees celsius.

Are these still good to use, or should I discard them and buy new? Not a huge deal to me cost wise (they are about $20 CDN each), but I'd rather not waste them if they are still as good as new. Conversely, I don't want to ruin my mercruiser bottom end if they are not.

cheers

I doubt there is an issue with that gear oil. I would use it.

If you don't want to use it, send it to me.

Oil does not have an expiration date, use what you have and go boating.

It is fine/safe to use.
