A lubrication system for a wind turbine is provided, the lubrication system including a lubricant consumer to which fresh lubricant is supplied and out of which used lubricant is extracted, a pump for pumping fresh lubricant to the lubricant consumer, a waste lubricant collector where used lubricant can flow after being extracted from the lubricant consumer, and a plurality of containers delivering fresh lubricant to the lubrication system.

An oil measurement apparatus for an oil-lubricated internal combustion engine has an oil dipstick and a guide for guiding the oil dipstick in an oil pan of the internal combustion engine. A fill level of motor oil in the oil pan can be recorded by the oil measurement apparatus. The oil dipstick has an operating element in a first end region for inserting and removing the oil dipstick in the guide and, in a second end region, has a measurement region for recording the fill level. The fill level can be recorded by the oil dipstick in a first state of the oil measurement apparatus and, in a second state of the oil measurement apparatus, the measurement region is completely drawn into the guide. The oil dipstick has a dipstick stop element between the operating element and the measurement region, and has a dipstick cover, which is movable between the measurement region and the dipstick stop element and is designed to at least temporarily cover the measurement region. In the second state of the oil measurement apparatus, the measurement region is covered by the dipstick cover at least in sections.
