Antiwear additives help protect metal surfaces against impact friction and wear between moving parts in an engine. Such additives work by adhering to metal surfaces and forming a protective film between moving surfaces. The most widely used AW additive are chemistries containing phosphorus and zinc. Some lubricant manufacturers also employ the use of antiwear additives containing boron, molybdenum and titanium among others.
Using a lighter weight oil than specified by the manufacturer will fail to fully protect against wear, while using a heavier weight oil than specified will overstress internal engine parts. Both can Castrol GTX trigger expensive repairs, so it’s best to choose the engine oil specified by the vehicle manufacturer for your climate and usage. Synthetic and conventional oil both start life as crude oil.
With its enhanced frictional properties, you get to save more money not only on fuel but on oil changes too. Despite that, still refer to your owner’s manual for the interval and frequency recommended by the manufacturers. In this review, we’re going to “go back to basics” and take a look at one of the primary motor oils in the Mobil 1 lineup, the Mobil 1 Advanced Full Synthetic Motor Oil.

With Amsoil vs Mobil 1 independent test results, ambient temperatures, driving habits, change intervals, and budget taken into account, either oil brand proves suitable for your four-wheeler. If you are open to recommendations, experienced car owners and enthusiasts strongly suggest Mobil 1 for high-mileage vehicles and Amsoil if you are looking for a premium synthetic oil variant.
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. 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 Castrol GTX would be game over. Every component remained within SAE specification in the interval tests and at the end of the 500,000 miles. Engineers arrived at a formula using these additives and created a test sample. The sample was sent to lab screening to determine if the formula would pass the required tests.
