Here is a video that will help you understand how to overcome the offset issue when using a crowfoot with a torque wrench.

A good example of over-tightening is the oil filter. However never used a torque wrench for a filter but since I had it out tried on my first oil change using what the 2014 owner’s manual said to use, 24 ft-lbs as I recall. I have a wrench that fits the bottom of the filter with a center location for the wrench so the reading is accurate. As I tightened it “felt” far to tight before I reached the specified torque - significantly from it! I loosened the filter and used what most filters say about tightening, turn ~3/4 from the rubber seal touching. In fact my 2017 owner's manual no longer lists a torque value it says turn ~3/4 from the rubber seal touching.

The drain plugs also have a rubber seal and IMO “feel “ is a good way to tighten it! I use a two step tightening process with a torque wrench for my wheels. I tightened the head bolts, on the 502 cid engine I assembled for my Street Rod etc. But for some bolts “feel” is fine if you have some experiance.

I don't want or need to understand it, as we've said use your torque if you like just stop trying to convince everyone it's needed for oil plugs and oil filters. I've use a torque wrench plenty of times for torquing heads and bearings, but for oil drain plugs and oil filters.

I've been looking for an excuse to buy a set of crow's feet wrenches and this looks like my cue, as my free oil changes are up and I'll be DIY starting with my next change about next January. Don't need them often but when you do it may be the only option that'll work. If would appear a flare-nut variety would be preferable for this application and all others involving a typical hex bolt or nut, and don't see any situation where the square type would work better. Any advice on this?

Agree. If you are concerned about rounding off or damaging the bolts or nuts, the flare nut variety is the way to go.

You ask for advice. Kevin Jones in post #24 shows a wrench to buy or consider the simple 6 sided box wrench I suggested.

However, I have often bought a wrench set for one specific need because I can justify it in my mind! Any rational to buy a wrench- like my wife and shoes! However I tried my flare nut 15 mm wrench and it was rounding the OEM drain plug hex as was my 12 point 15 mm box wrench. In fairness, most of my wrenches are Craftsman, but that metric flare nut set were cheap. If you’re going to buy the set, get quality.

I am really surprised by this response. I am sorry if I offended you. Zjoe6 brought up a valid point (the offset issue) and I provided a solution which was also mentioned by RonC. I very much enjoy detailed technical discussions on automotive issues. I am certainly not trying to convince anyone of anything. People can take in all the information everyone provides and then make whatever choice that suits them. I welcome all inputs and try to understand everyone's point of view.

I have a set of those as well as the flex-head variety, but you can't use a torque wrench with them. I've never used a TQ wrench on a drain plug before but in the past they always screwed into steel threads which isn't so critical. When I had motorcycles almost all bolts screwed into aluminum and I always torqued them. I think doing that as a rule is a good idea.

I can see how a flare-nut wrench might not be as robust as a the conventional open-end type, but I can't see using them for anything requiring high enough TQ values to break them.

But I already do understand it. But thanks anyway. If you need any help with it let me know.

Just adding to this as I just went through this yesterday.

Regarding the size drain plug:
-Tried a 15mm flare wrench (harbor freight, lulz), didn't work, started rounding off
-Tried a 15mm box wrench (Husky), 12point, didn't work, wanted to round
Said screw it and put my 6point socket on with a short extender, all 3/8" drive. Threw a cheater bar (handle from jack) on it and socked it off. I put the socket on first, then the extension. The extender was small enough versus the socket to snake under the oil cooler (it may have put an ever so slight bend on it, but nothing to worry about). A wobbly joint extender probably would have come in clutch, but I didn't feel like looking for it lol.

If it matters to anyone, I'm using 5w-30 Mobil 1 Extended Performance. I have the oil cap for 0w-40 to swap on, but won't until the oil becomes reasonably priced. Cheapest I found was $50 for 6qts. Pretty pricey versus $23 for 5+qts jugs at wallyworld… And I'm sure the dealers aren't stocking/filling with 0w-40. They'd have to be pretty high on Vette servicing volume to stock it and even then there's no way of knowing what's coming out the tank. Just my thoughts.

Also wrecker3, good call on the funnel. Looks nice, wish I saw it a day earlier as it was delivered the day after I did the change.
