If you have an RC car that has shocks on it then you likely have shock oil inside (shocking right?). One issue with shock oil that many people wonder about is there are a bunch of different \u201cweights\u201d (yes I know it\u2019s actually viscosity but everyone uses weight so don\u2019t yell at me) and brands and that leads people to wonder whether they can mix them or not. \n\n\n\nYou can mix RC shock oil without it causing any problems to your shocks or RC car. If you mix a 30wt oil with a 50wt oil you will end with about a 40wt so the viscosity is something to keep in mind but mixing different brands won\u2019t harm anything. \n\n\n\nBefore you start mixing the shock oil make sure you know what viscosity you are aiming for so you can put the right amount of each into the mixture to end with the right weight oil in your shocks. \n\n\n\nNow that we know that you can mix different brands and weights of RC shock oil there are some other important questions that you will likely have about your RC shocks and their oil so we will try to cover the most common questions about shock oil in the rest of this article. \n\n\n\nWhat shock oil should I use for my RC car?\n\n\n\nThere are tons of different shock oils on the market and then if you check out some message boards or forums you will find many people even recommending using dish soap or other random things in your shocks! \n\n\n\nDo you know what you should really use in your RC shocks? \n\n\n\nYou should only use silicone shock oil in your RC shocks if you don\u2019t want to take a chance on damaging your shocks. You should use 30-40wt. shock oil in your shocks but depending on how stiff you want your shocks to be you can use different weights. \n\n\n\nThe higher the viscosity (weight) of your shock oil the stiffer your RC\u2019s springs will be so if you start with 35wt. and it is too stiff then you might want to go down to 25wt. and see if you like that.\n\n\n\n If 35wt. doesn\u2019t make your shocks stiff enough then just go with a 45-50wt. shock oil. \n\n\n\nCan I use motor oil in my RC shocks?\n\n\n\nAnother common question we hear quite often is whether you can use motor oil in your RC shocks. Afterall motor oil is something that most people have lying around in their garage so why not use it? \n\n\n\nMotor oil will likely harm your RC shocks as the petroleum in motor oil could react badly with the plastic of your RC\u2019s shock. RC shock oil is silicone based and only silicone based oil should be used in your RC shocks. \n\n\n\nIf you absolutely have no choice then you could probably get away with using motor oil and honestly if everyone used motor oil the only people who would complain are those whose shocks were destroyed! \n\n\n\nWhy would you take the chance of destroying your shocks and possibly something else on your RC car if the shock breaks on a landing? \n\n\n\nRC shock oil is cheap and can be found virtually anywhere (even online here) so why would you risk damaging your car? \n\n\n\nWhat kind of oil goes in Traxxas shocks?\n\n\n\nSince Traxxas is a super popular brand right now with many hobbyists owning one (or more) Traxxas RC vehicles many people often ask what they need for their Traxxas cars specifically. \n\n\n\nAs long as you use RC shock oil (silicone) you can really use any brand that you want. You don\u2019t have to buy Traxxas\u2019 shock oil (although it\u2019s not a bad choice). \n\n\n\nAs mentioned earlier you will want to make sure to find the right viscosity (weight) shock oil that you prefer but that is something that is a personal preference and will also vary from model to model and depend on where you are using your RC car. \n\n\n\nFor most people just getting the cheaper RC shock oil that is the weight you normally run will work perfectly. \n\n\n\nHow do I add oil to my RC shocks?\n\n\n\nSo we covered a decent amount of common questions about RC shock oil but this is the biggest one. How do you do it? \n\n\n\nIf you are brand new to RC vehicles or you\u2019ve never had a hobby grade car before you might not know how to even add RC shock oil or how to change yours out. \n\n\n\nThankfully it\u2019s pretty simple. \n\n\n\nTo add or change your RC shock oil you simply have to take the shocks off the RC car, remove the springs from the shocks (on some models), and then unscrew the cap at the top. \n\n\n\nMost of the time you will want to actually change your shock oil rather than just adding oil to it but if the oil is brand new and you want to stiffen or soften the springs by adding different weight oil this is how you do it. \n\n\n\nOnce you have filled the shock back with oil simply screw the cap back on, reattach the spring, and boot the shock back onto your RC car. \n\n\n\nTo see exactly how to add oil to your RC shocks you can also check out the video below. \n\n\n\n\nhttps:\/\/youtu.be\/1_d1nEquS6Y\n\n\n\n\nWhat weight is Traxxas shock oil?\n\n\n\nIf you have a Traxxas RC car then you have likely seen Traxxas shock oil while you were searching the store. One issue that many people run into with the Traxxas shock oil is that it doesn\u2019t give the weight (viscosity) of the oil! \n\n\n\nThat seems like a pretty big thing to omit especially since every other shock oil says what weight the oil is while Traxxas doesn\u2019t. \n\n\n\nThe standard Traxxas shock oil is actually 30wt. if you go to your local hobby shop or online and find Traxxas oil that doesn\u2019t give a weight on it that is what the weight of the oil is. \n\n\n\nNow just because that is the standard weight of the Traxxas shock oil that doesn\u2019t mean that is what weight oil you should run in all of your Traxxas RC vehicles. Most people actually prefer to have a little bit stiffer shocks so they run 40 weight oil in them.\n\n\n\nHow stiff or soft you want your shocks is difficult to determine if you are new but most people prefer using 30-40 weight shock oil. \n\n\n\nHow full do you fill RC shocks?\n\n\n\nThe last commonly asked question we will cover today is how full you should fill your shocks. Many people get their RC shocks all the way off, apart, and drained and then have no idea how full they should refill them! \n\n\n\nRC shock oil should be filled right up to the top of the shock. That will give you a little bit of extra room (space in the cap) but will still keep your shock working properly. \n\n\n\nIf you do end up with too much oil in the shock it will just leak out and won\u2019t harm anything so it\u2019s better to have it too full than not enough. \n\n\n\nIf you just fill it to the top everytime you really can\u2019t go wrong. \n\n\n\nConclusion\n\n\n\nI hope today\u2019s article about RC shock oil helped answer any questions that you had about whether it can be mixed, what weight oil to use, and even how to put the oil in. \n\n\n\nRC shock oil is really quite simple and cheap as well (although not as cheap as motor oil). It\u2019s easy to change out your shock oil as well so it should be done regularly to keep your shocks and your car running down the road properly.
