BJ8 Oil Drain Plug

[Scot]

What socket/wrench size is everyone using on this plug?? A 1 1/8" is too large and 1 1/16" is too small. A 1 3/32"? Very uncommon but may work. My plug is pretty rounded off from using the larger one over the years. I want to give my new drain plug a good start in life! An internet search reveals the same confusion! TIA

A Whitworth wrench will do.

Thank you! Looks like a 5/8' Whitworth or a 28 mm would do the trick as well.

Crescent wrench works every time.

Crescent wrench works every time.

Probably a lot of operator error, but that's what mostly caused a rounded off plug!
