11. Is Shell Rotella® T motor oil going to have less zinc in 2007?

Yes. The API CJ-4 (next generation) Shell ROTELLA® T multigrade motor oil will have a slightly lower level of zinc than the current API API CI-4 PLUS Shell ROTELLA® T. Zinc is typically used as part of the anti-wear system within the oil. However, less zinc in API CJ-4 oils compared with API CI-4 PLUS oils does not mean increased wear. In fact, wear protection is one of the key areas where the API CJ-4 category provides improvements over API CI-4 PLUS. (Other areas include; oxidation stability and soot control). The new API CJ-4 Shell ROTELLA® T multigrade motor oil also meets the requirements of earlier API performance categories such as API CI-4 PLUS, CI-4, CH-4, CG-4, as well as others, and can be used in engines specifying any of these performance categories.
