Has anyone used the engine oil drain valve sold at the following site?
QuickOilDrainValve.com - the best way to change oil
A friend who has a couple classic Minis swears by this. One version has an adapter for a hose connection. I was wondering if this device might make it much easier to change oil? I have had my new Z for about two weeks and haven't been underneath yet. Would you still need to remove the cover under the engine to change the filter?
Thanks
