I don't know for sure.. but am about to do the exact same thing you are... as long as it has been sealed up tight, i can't imagine anything in it has changed, but I could be wrong. wait for others to chime in.

Yes shock oil does go bad but not quickly becuase most oils are silicone. Most of the time the oil becomes contaminated and dirty long before the oil breaks down. But since your oil is still in the bottle, it should be good to go. So the oil in shocks should be changed with use not so much with age.

Not sure if it goes bad in the bottle but I had some 40wt trinity silicone oil in the shocks of an old tamiya I have and when I changed it it after 9 years it was sludge. It must have turned into 80wt ahaha

If it seems to thick for the wt it is then more likely its trash.

What weight would you reccommend for a short tight Asphalt course with one 75-80 foot straight?
Do you guys rebuild shocks that often? What do you replace when you do?

I think as long as the shock is still working fine, I wouldn't change. I was forced to rebuild my rear shocks a couple months ago when the right rear decided to put shock oil everywhere onto the car and body.

Hmmm. I figured i should change because i bought the car used a few years ago, and never changed the oil, so i dont know whats in there. I just want to know what i have in it.

I do HATE changing shock oil though......
