Mobil 1 M1-103A
Size: 64mm x 14
Fits Perfect on Mobil 1 M1-103A.. for 2010 Scion XB. Snaps on and doesn't fall off, easily removed after the oil filter is loose.. Very happy with the fit, function and quality!

Works perfect for BMW S63 engine.
I used this to change the oil on my BMW M8 with the S63 engine. It was a perfect fit. It extended far enough onto the filter housing to be quite secure with no risk of slipping off and stripping the housing. It was snug on the housing and did not bind up due to having a loose fit. The tool feels well-built and I suspect it will outlive me given my occasional personal use. It would still probably hold up well even for daily shop use as long as it was not abused (repeatedly dropped, slammed around, etc).
