Torque wrenches and floor jacks...
So I have a few questions on these two items. Currently I have a craftsman low profile 2.5 ton floor jack (I think it was around 50 bucks) and a craftsman "digitork" torque wrench. I have had these for quite a long time...I believe they are both around 6-7 yrs old. I do not wrench on my car all that often as I do not mod as much as before. But I will be installing H&R springs soon (they have been sitting for the past 3 weeks) on the M3. So here are my questions:
1. Would the craftsman torque wrench even be accurate anymore? I have heard the craftsman wrenches suck and are a throw away item and that it is far better to buy an expensive torque wrench. 2. How often should you "service" the floor jack? I take it the only thing that needs to be replaced is the oil? Or would it be better to invest some money into a spendy aluminum floor jack (I think they are a few hundred bucks)? Sorry if these questions sound noob-ish, but I really have not considered the maintainence these tools may need before. I figure it is better to be safe and have them serviced accordingly or replace with newer better units for my own safety and also to be sure all the bolts/nuts on the M3 are tightened correctly! Hope to get some good input on this.

On the torque wrench, you are ok. They do not go out like that with out a lot of use.
I have a torque wrench since 2000 and I only inspect the torque quality one ttime.

Tool maintenance
Quote:
My philosophy is to buy the very best tools I can, as they will last a lifetime, in many cases. I've got some Snap-On sockets I got in college 35 years ago which are still perfect. I ve never broken a Snap-On tool. When you can afford it, you may want to upgrade items and donate your old ones to your nephew. Precision Instruments makes some nice torque wrenches (The Tool Warehouse), and you can find some cool low-profile Euorpean jacks at The Ultimate Garage. Most jacks are Chinese-made now, okay but nothing special. I've got an older American-made Walker floor jack that will outlive me.

Having been an FAA Airframe and Powerplant mechanic in my previous life,
we always ensure those high precision tools were periodically calibrated, oiled and stored at their lowest settings. But on yours, I wouldnt worry about it, since you use them for very low torque settings anyway, and just release the pressure on your jack when you store and you'll be fine
