Does fork oil have a limited shelf life?

As the subject says....

I have little bits of fork oil that I accumulated over the years(maybe 4years)... all the same oil... Putoline synthetic fork oil. So I was just wondering if the oil has a limited shelf life?... Can I add the little bits together and use it?

Then, how much oil is needed for each RVF fork? I don't remember the exact amount... but I think it's around 450ml?? is that right for each fork??

I think your thinking of brake / clutch fluid which is hygroscopic, an unsealed container will attract moisture from the atmosphere, which then boils when you heat the brake fluid up, resulting in crap brakes.

Engine / Fork Oils vary by their makeup, the more complex an oil the less time it is good to keep, a general rule of thumb is 2 - 5 years.

Engine Oil Bible

Have a read of that, theres a paragraph specifically dealing with oil lifetime.

not mistaken it for brake fluid neo,im well aware of the brake fluid not being as effective over time.

i just remmeber the tutor at college mentioning oil not being as effective if left over time.his example was if you have oil sitting in the garage for a very long period of time and then decide to go do a oil change then don't,he then went into the reasons why and what happens but sadly i can't remember all of that.

Thanks.

I assume that's per fork leg. Also the 74mm level is measured from the top of the fork leg to the top of the oil... I did this before just not 100% sure of the measures...
