Why Do We Have 0W-40 ESP?
The 0W-40 began in Europe but in the USA we require the ESP spec oil for GM vehicles.
What is the ESP part of the Mobil 1 Oil specification? Low Sulfur & Phosphorous Content: Helps To Reduce Poisoning Of Gasoline Catalytic Converters. This is a major problem for newer cars. In the past high Phosphorous oils were destroying catalytic converters. In response to this manufactures have lowered the additives to extend the life of emission systems.
High Phosphorous oils attack the converter matrix coating and requires replacement of the converters when they fail. This is typically detected from the monitoring O2 sensor downstream of the Catalytic Converter.
On the flip side, older engines that depend on the additional phosphorous content to extend the life of metal to metal contact parts such as camshaft lobes began to fail. If you own an older engine without roller camshafts pick your oil wisely!
The 0W-40 oil has a weight of SAE 0W-40, meaning it has an SAE viscosity rating of 0 in cold temperatures and a rating of 40 at normal operating temperature. A numerical code system created by the Society of Automotive Engineers (SAE) grades motor oils according to viscosity--the higher the number between 0 and 60, the more viscous (thicker) the oil is. Most consumer motor oils are graded by two numbers, with the first number indicating cold weather (Winter or "W") performance.
