| Woah, very helpful shock tip if you have no oil to fill them!!
Hey guys i recently busted a shock and had no oil and ive been running hydralic steering fluid in my shocks and they run like theres 30wt oil in them! haha just FYI if you dont have oil, power steering/hydralic fluid WORKS good! ( and dont bash me for doing this, it worked for me and im sticking with it, i dont care if it harms my shocks or not lol jk ) Last edited by shadowrejects; 06-10-2010 at 08:29 PM. |

I'm sure it will work for some length of time, but I can foresee issues arrising in the future. Hydraulic oil is not designed with the same intention as shock oil. It is designed to be compressionless, lubricate internal working components in hydraulic systems, and prohibit rust in hydraulic systems. I personally think it would be OK in an aluminum shock, but I'm not sure how well it would work with plastic. Then again, if it does play well with plastic, you should be good to go. Assuming the weight is what your looking for.

Better than me, I once used cooking oil in my shocks when I was stuck. Worked OK but pretty light for shock oil.

Steering fluids (brake fluids) are available, or used to be available, in different grades. I once put the wrong grade into a Chevy S10 Blazer and fried the brake system. That was 30 years ago or so. Not sure if grades are different today. Back in the day, some plastic compounds (O-rings) did not like some hydraulic compositions or visa versa. Damn, I'm an old "fawk".

I have used power steering fluid and auto tranny fluid interchangeably for years and I know for a fact that there is all kind of plastic inside a transmission. Brake fluid is a whole nother animal though. I have used it to stip paint off styrene bodies though, so maybe it's safe for plastics, or maybe just safe for short times.

I would be concerned about the petroleum base of the oil and degradation of the rubber components in the shocks. Silicon oil is used for a reason in RC shocks. I'm sure it will work just fine for a temp fix till you get the right shock oil though! |

Dude!! HYD oil is perfectly safe for o-rings and plastic..what do you think is in valves,cyls and pumps?? And not for compression?? Theres hyd systems that run upward of 3,000psi?? Now brake fluid I wouldnt suggest,it will swell normal o-rings and soften plastic and powersteering fluid is a hyd fluid..

A buddy of mine used vegetable oil once for a temporary fix... but real shock oil is like $3 a bottle or something close. I'd say that using the real stuff is always the best bet for the long run Especially when replacing 4 shocks will cost around $30 for cheapies. |

| Silicone oil is used mainly because it's more impervious to temperatures than petro based oils. That is it doesn't change viscosity as much with changes in temperature.

Well I blew a hose off the Jeep steering this weekend and just used 27 bottles of Axial shock oil because it's all I had. Should be same thing then....
