To permit engine oil levels to be checked accurately and cleanly without the need for a rag or other such wiper, a housing adapted to be attached to the dipstick tube, or other engine or engine compartment part, contains a body of wiping material having a slot therein through which the dipstick may be inserted and removed clean of oil so as to be ready to be inserted into the dipstick tube again to check the engine oil level.
