Two Simple Ways to Test Your Unused Motor Oil at Home

Oil is the lifeblood of your car’s engine. Does new unused, unopened motor oil ever go bad? One motor oil expert recommends two simple ways to test your unused oil at home.

Buying Oil in Bulk to Save Money

It’s not unusual to buy in bulk to save money. It’s a great way to fight off rising costs and also a way to ensure that something you will eventually need like select parts for your car or truck will be available when the time comes.

Or, what if the Old Man has unopened boxes of oil on the garage shelf that has been there since the Carter Administration? Is it okay to use it in your car? Even in a pinch?

These are just a few of the oil-burning questions many car owners have.

Oil and Oil Product Considerations

In an earlier article we learned about an oil test comparison performed by a well-known engineer/mechanic on the Project Farm YouTube channel who demonstrated how not all oils are equal or live up to their price tag―especially with one motor oil you should not trust for more than 5,000 miles.

Which seems odd today since most motor oils are advertised at least 10,000 miles or higher―along with a price tag to match the promise.

From this same YouTube channel we also learned about some of the consequences of adding an oil-stop leak product to your car to put a stop to an oil drip that is staining your garage or driveway.
