Shell Rotella Engine Teardown

This table had parts from the experimental oil, which had a high-temp/high-shear rating of 3. Lubricant engineers believe the new category will call for a range of 2.9 to 3.2.

A North Carolina fleet has been running a group of trucks on three different Shell Rotella oils -- a 15w-40, a 10w-30, and a 10w-30 that's been altered to provide a lower high-temp/high-shear number than is currently approved. A teardown of one of each after more than half a million miles shows virtually no difference in wear among the three engines. Learn more here. (By Deborah Lockridge, Editor in Chief.)
