harbor freight 1/2 metric impact socket set has a 30 in it and is less than @25 for the whole set! Nice deal.

But really, if the bolt is that big, you could use an adjustable on it or even a monkey wrench and not worry about stripping it.

Little late, but for anyone looking in the future, I've used OTC 5060 for these exact drain plugs. It's actually a socket for 6.2/6.5 GM Injectors, but it's a 30mm, 3/8s drive (or 7/8 hex) and it's about halfway between shallow and deep.

30mm for an oil drain plug????

You've gotta be kidding me.

I do the oil on a car that requires a 46mm socket.
Bonus points for whoever guesses the brand and/or type of engine...
and just to say, it's a commercial brand of vehicle, not a giant caterpillar of some sorts. Granted though, it's not a daily driver...

Will take pics to prove it next time he stops by...

I'm talking oil drain plug, and I seriously doubt any of those have a 46mm plug... I can believe they use a large socket to remove the oil filter though? Wouldn't know, as the cars from audi/VW/seat/skoda I work on have an oil filter with "wings" on the bottom.

If all you're doing is oil changes, those brands are big time overkill. They're made for cranking down with serious muscle. Go as cheap as possible.

Are you sure its not 1-1/4" ? Alot of the british stuff (old) was whitworth then just regular SAE. I work on alot of jaguars and dont really see tons of metric fasteners

It's what I was told by a knowledgable friend on a Jaguar forum. I can't swear by it on personal experience. My XJS is a late model so the SAE was slowly going away. For instance, most to the screws in my car are Pozidriv but a few are Torx as the transition was done later in the year.

30 mm is a common size for axle nut sockets. A drain plug is not a high torque issue, so any good socket that is sized correctly will do the trick. I would buy a decent socket and use it. Craftsman, almost anything. That is a thick head on the plug. Many drain plugs are thin, and would need a socket with little or no chamfer, but for a plug with a head as thick as this one, it really doesn't matter.

This monkey wrench works perfectly:

In my case..... and speaking from experience. I would buy the Snap-on 30mm and a Craftsman 18" breakover.

Keep the two mated and in my "oil-change" drawer in my tool chest. Wrapped in a rag, to catch any oil.

Since I'm the only one touching the car.... lossening/tighting the bolt, I don't worry too much about needing a lot of torque, reducing the worries on rounding. So a short breakover works just fine. But I want a good socket.

The $20 additional for a good socket spread over the 10 years you own the car is worth it.

Yep, know about that 8 qt thing.

Again, thanks for all the input.

Nice XKR in your avatar Mike14k. I tend to agree with you on the get a good socket. I got the Stahlwille because it was a pretty good price (half a Snap-on) and seemed to be good quality from what I read on here. Also curious about the slightly different form factor that it has.

Went ahead and got a CDI torque because I needed it for something else. I probably won't use it often but might be helpful to help learn the feel of what the correct torque is.
