How Mobil 1 Annual Protection lasts 20,000 miles
Thus begins the second portion of the video: the tests.
One of the many tests was called TEOST 33C. In the test, oil flows around a stainless steel rod with varying heat cycles above 200 degrees to 480 degrees Celsius. Meanwhile, the oil also flows through a reactor vessel where it's bubbled with nitrous oxide and oxygen. In the end, engineers clean off the oil on the rod then weigh it against the rod's original weight to see the deposits left on the component. This is an incredibly difficult test for oil blends to pass and one of many intricate parts that goes into oil development.
Next came the Oxidation Stability Test and the Thin Film Oxidation Test. The Oxidation Stability Test ensures that the oil maintains its proper viscosity over its lifetime. The Thin Film Oxidation Test looks at how much oxidation builds up on parts.
Then came the engine tests. A GM turbo test with a 1.4-liter 4-cylinder Ecotec engine certifies that the oil is compatible with GM's engines. It's a 500-hour test that cycles from high to mid rpm. After the test, the turbo was cut apart and examined, and Mobil 1 Annual Protection passed. Another engine test involved a Toyota 2NRFE engine. It's a 200-hour test and it examines the lifter buckets after the engine cycles from idle to 4,300 rpm 24,000 times. Again, the oil passed.
Next up were the MADS (mileage accumulation dynamometer stand) tests. Using a 2015 Lexus NX 200t, a 2016 Ford Fusion SE, and a 2016 Chevy Malibu, all with turbocharged 4-cylinder engines and each given a different weight of oil, Mobile 1 ran the vehicles up to 120,000 miles and performed oil changes at 20,000-mile intervals. Engineers tested the oil every 5,000 miles and simulated various driving conditions. Once the tests were complete, the three engines were torn down and inspected for varnish, sludge, carbon deposits, and wear on the parts.
In addition, the oil that was removed every 5,000 miles was broken down and analyzed to see what metals were in the oil. This determined what components may be wearing too quickly. This process was also used to ensure that the viscosity and other oil properties remained within the oil's requirements during the full 20,000 miles.
Finally, Mobile 1 used the dynamometers to perform a 500,000-mile highway test with a Chevy Silverado. If any component the oil touches failed during the test, it would be game over. However, the Annual Protection survived. Every component remained within SAE specification in the interval tests and at the end of the 500,000 miles.
There's much more to take in from the video, and after watching it, you'll realize that there's more than meets the eye in a simple bottle of oil.
