Can you really trust the oil in your car for up to a year? @Jalopnik /Twitter:

Jason Fenske took to his YouTube channel, Engineering Explained, to break down exactly how much goes into a high-mileage engine oil. Fenske had the opportunity to visit the creators of Mobil 1’s Annual Protection motor oil and study the huge amount of testing that goes into making sure the oil can withstand 120,000 miles.

Of course, the process of creating the oil begins in a lab, where the professionals at Mobil 1 combine a variety of chemicals to make sure that the resulting product is reliable and capable of achieving the goals they’ve assigned to it. After that, some interesting methods of testing take place.

The oil is pumped through engines to test how well it protects each motor. That’s pretty standard stuff, but following that stage, the MADS testing begins. This stage requires the oil to be tested on cars running 120,000 miles on outdoor dynos. The engines of the cars are then taken apart to study how well the oil performed.

It’s an interesting dive into the development of a product that is too often taken for granted. And don’t forget, even the best oil in the world will be no good if the filter isn’t up to the task.
