Do the Caldera 10e shocks ship with oil already in the shocks (original shocks with the vehicle, not replacement). I've read where people have received RC cars with oil-filled shocks that shipped without any oil. When just pushing down on the chassi, my shocks stick some around the middle of the shocks' extension (doesn't seem to stick at the point where the shocks are fully-depressed, but somewhere in the middle between fully depressed and fully extended). I understand how to adjust the shocks, but wondered if I needed to fill with oil. I would check myself, but don't know how to and don't know what type of oil to add if there was no oil. Also, how firm should I set my shocks?
its hard to explain how to fill shocks with words, but there are youtube vids showing how.
I doubt that your shocks are empty, but many RTR models ship with shocks not 100% full. Even 5% of the oil missing will cause the shocks not to work properly.
Shock oil can be bought online or at hobby shops. 35-40weight is common for 1/10 scale RC's.
Once you find a video on youtube showing how, you will see its not hard to do and you can top off the fluid yourself.
