Mobil 1 is a brand of synthetic motor oil and other automotive lubrication products. Originally developed by the Mobil oil company, it is now globally marketed and sold by ExxonMobil.
Mobil 1 engine oil was introduced in 1973.[1] The brand range now includes a variety of engine oils, oil filters, chassis grease, transmission fluids, and gear lubricants.[2]
In 1998, Mobil challenged Castrol over the discovery that Castrol was processing conventional oil and calling it synthetic. At the time, Mobil 1 was still created using a true synthetic basestock, which is more expensive. Mobil lost the advertising "complaint", and, as a result, the definition of 'synthetic oil' including Group III heavily refined to the point of considering it synthetic. In response, Mobil allegedly downgraded their process to the less expensive process. Lubes N' Greases magazine reported shortcomings in the ability to pass the tests that the original Mobil 1 formula was able to.[3]
