oil changes

If I may ask what is probably a stupid question (not my first!)

What's wrong with just using the old " tighten them as much as you needed to loosen them" method? :dontknow:
Can a 6mm bolt tell the difference between 10 lb/ft and 12 lb/ft?

The torque needed to loosen a fastener can vary a lot from that needed to tighten it. Steel screws into alloy cases usually take more torque to remove than to tighten. Same goes for fasteners with threadlocker on them. In other cases a fastener may have loosened over time, from vibration mostly. That fastener needs to be tightened more than the torque it took to remove it. A fastener cannot tell what it is torqued to, but an inadeqauately tightened fastener can leak, allow the item being attached to warp or be damaged, or it can vibrate loose and back out completely, causing loss of parts and a possible catastrophic failure. An overtightened fastener can strip the threads on the fastener or the item being screwed into, and it can stretch to the point of being weakened, even to the point of failure. Proper tightening is important...and it is a bit of an art. It takes the right tools, used properly, and the proper fasteners and technique. There is certainly a little wiggle room, but a rookie needs to be aware of the possible consequences of straying too far in either direction.

Note to self: Get the plugs; take them to the dealer for the next oil change... :shocked:

The only time I've ever broke a bolt is when I used a torque wrench. nojoke
I do use them on things like head bolts but other than that I go by feel. I would not use a torque wrench on oil filter cap bolts, these have an o-ring so just get it tight by hand. IMHO
