I try to reuse by sucking it up into an old bottle and then re-squirting it into the shock…

Unless it's like new oil I just put in where I need to change the valving, I usually just dump what's in the damper and refill with new.

I capture it in a small glass dish.   (I think it's for candles or something, not sure).

Usually after some use (especially on off-road cars with aeration shocks), the oil in the shocks accumulates some dirt/dust and gets dirty. When you see that, replace it by fresh oil.

[Wheel_Nut]

The potential problem is dirt contamination.   It will become abrasive, so its probably not very helpful to maintain the life of shock seals.

I never reuse oil, it always looks dirty. I rebuild my offroad racers shocks every few months and the oil is always filthy. The onroad cars get done every 6 months (I probably should do them more often, but you know, lazy and maintaining 10 race cars is a lot) and the oil is cleanish but I still replace it

I have a big range of oils which hurt when I bought them but they last ages as you don't use much so it isn't actually a big cost to replace the oil. 

In saying that, I have cars that were built 4 years ago and I haven't had to do anything as they are still running fine. I expect the oil in them will be pretty clean but if I check then I have to rebuild the shocks so, you know...

You should have seen the oil on my shocks on the FoxShot when I rebuilt it after standing for 28+ years. It had seen "quite" a bit of use in its old days too!! Just a little grey!!

Now if only they will give more of their grease in the kits as well. 😁

If you want some extra grease then give me a shout, I use Labelle 106 so have a spare tube or two somewhere.

There’s a really good thread on here about different greases, it’s my handbook basically. You have to be careful of automotive greases and lubes as they will often eat plastic over time. 

I use WD40 for degreasing only and wash it off afterwards as that stuff is evil. Labelle 106 for plastic and an rc moly grease for metal to metal. To stiffen diffs I used to use Tamiya AW then switched to 3Racing 2 million Wr diff oil and am planning to replace that with putty when I can get the energy to rebuild all gearboxes. 
 

I try not to be too worried about cost of greases/lubes as you don’t really need much and if your going through it too fast you either have way more models than my 15 or so, or are being far too liberal with application. 
 

I tend to use graphite powder for locks as a dry lube on my CVDs/XVDs etc on my clods and things as I’m only just getting my head round dry lubes. 
 

edit :- 3in1 old school oil is great on motor bushings and bearings too, less wear and bound to be a couple more rpm.

Thing is, my 12 years old oil still is golden yellow, like new. 🤔

I have half a bottle of Tamiya shock oil from 1983 and it still looks like new.

I used some ‘old’ yellow oil from the late 90’s I found the other week.  As far as soft damper oil with standard CVA-Mini one hole valve setting, it still worked just fine.   

I’m concentrating more on not leaving air inside the damper housing, I suppose.

I use old schools 3in1 on brushed motors all the time , and wheel bearings ( blow off excess with air gun ) 

recently I found 3in1 makes a formula for electric motors so I bought that when my last of regular formula ran out. So far so good.

If they are the 'basic' CVAs with the metal one piece shaft/damper, the coating can wear off and go into the oil.  My DT-03 is ~5 month old and I decided to change up the shocks with better o-rings and different oil viscosity.  I popped the fronts (minis) open and they were fine, and I saved that oil.  The rears (shorts) had a lot of particulate floating around in them.  I didn't save that oil.  You could see that it had worn off of the shaft.
