8. Kill Mange, Mites, and Fleas

If you have pets, then you have probably also encountered flea infestations. Chances are, you have also felt quite helpless when your pets developed allergies to modern flea medications, or worse yet, got very sick from them.  Surprisingly enough, motor oil can be used to get rid of fleas, mites, and mange.

Just be sure to wash it off thoroughly and use with caution.  Motor oil can be used both in a crisis and in these times if you have no other remedy available for these problems.

9. Keep Hand Tools Clean and Rust Free

Hand saws, drills, and many other hand tools require cleaning and oiling in order to keep them in the best possible condition. No matter how much lubricating oil you keep on hand, chances are your stock pile will run out long before your hand tools need to be discarded.

You can always try used motor oil to keep your tools free of dirt and rust.

10. Filter and Reuse as a Lubricant

Once motor oil is too dirty for use in an auto engine, there is no point to trying to filter it and reuse it for that purpose. There are still many other devices that build up less heat or have less stringent tolerances between parts that may still benefit from used motor oil as a lubricant.

Just be sure to filter out the oil so that you remove as much debris as possible.

When using discarded motor oil as a lubricant, it is also important to bear in mind that the oil itself may have broken down a good bit from heat generated by the engine.

Even if you filter the oil, it will not alleviate this problem.

You may need to change the oil more often, or pay more attention to device operation in order to avoid the kinds of damage that would normally be avoided by using oil as a lubricant.

11. Mix With Gas to Run Tractors

Unlike motor vehicles, older style tractors can run on a surprising number of different fuels without being damaged.  In this case, you can stretch fuel reserves for your tractor by adding some motor oil. You may be well served by filtering out the oil so that stray bits of metal or other contaminants do not damage the tractor engine.

Since every tractor is a bit different, you should start off with small amounts of oil and then see how the engine performs.  The last thing you will want to do is add too much oil and wind up with a seized engine.
