Shell Rotella 550019921-3PK T6 5W-40 Full Synthetic, Heavy Duty Diesel Engine Oil - 1 Gallon (Pack of 3)

This is good oil, and is a Group Three "synthetic" which means it is a highly processed "regular" oil which performs as well as a "full synthetic" and thus, by legal decision, can be called a synthetic in the US. It would NOT be called a synthetic in Europe. Wnat to know all about "Group III," try the "Bob is the Oil Guy" website... (BITOG.com) Using this oil has eliminated the little start up puff of smoke on my high miles Toyotas and reduced oil consumption to almost nothing. - Customer Reviews
