This kit includes EVERYTHING you need to make oil analysis simple and easy.  It includes the vile for obtaining the oil sample, it includes instructions, a return shipping label, and USPS priority box, and even a rubber glove!  Make these a part of every oil change to ensure your engine is running at peak performance!  Knowledge is power, and knowing what goes on inside of your engine is the best insight you can have to determine proper oil change intervals, catch injector or head gasket issues before they cause damage.

The box is already addressed, so you only need to place the sample in the box, seal, and ship. The box can be dropped off at any USPS post office or handed to your local mail carrier.
