Castrol , Pennzoil & Valvoline) also making D1 Gen 2 now ?
There may have been some truth to that with the older Mobil formulations, SM for example. When Katrina knocked out their PAO production plant and Mobil was scrambling to meet demand, there seems to have been a problem with the formulation. Valvoline, then Castrol used this in their marketing. Valvoline said they had 4 times the wear protection of Mobil 1, and Castrol said they had 8 times the wear protection.
With the latest formulations of Mobil 1, I don't think there is any issue of wear protection. In fact, on Mobil 1's website, they talk about how their oils provide unsurpassed wear protection according to the Sequence IVA test.
Here is a copy of what they say, and the link to their website.
"What is the difference between Mobil 1â„¢ Extended Performance High Mileage motor oil, Mobil 1â„¢ High Mileage motor oil and other high mileage motor oils?
Wear protection starts with reducing metal-to-metal contact. According to the industry-accepted Sequence IVA engine wear test, the Mobil 1â„¢ family of motor oils offers unsurpassed wear protection. Mobil 1 Extended Performance High Mileage and Mobil 1 High Mileage oils are part of our line of advanced full synthetic motor oils using the latest in additive and base oil technologies. In addition, Mobil 1 Extended Performance High Mileage oils are the only high mileage motor oils that guarantee 15,000 miles of protection. "
