Shell Lubricants has launched the new “Shell Rotella Energized Protection portfolio,” featuring a new synthetic-blend engine oil and a new formula for its full synthetic. As well, all Shell heavy-duty engine lubes have been consolidated under the Rotella brand, meeting all on- and off-highway needs. All multi-grade engine oils in the line meet API CJ-4 standards while CI-4 PLUS products have essentially disappeared.

The Shell Rimula, Pennzoil Long Life and Quaker State HDX product names will disappear as of this month, their applications covered by one of the Rotella lubes in six performance and quality tiers.

The lineup is led by the new formulation of Shell Rotella T6 full synthetic 5W-40 that’s said to offer superior fuel economy plus protection for the latest low-emissions engine technology.

The others include the new Rotella T5 Synthetic Blend and Rotella T with Triple Protection (taking the ‘T4’ place but not called ‘T4’). Then there’s Rotella T3 15W-40 (taking the place of Pennzoil Long Life Gold) and Rotella T1, described as “a quality straight grade engine oil” in 10W, 30, 40 and 50. In Canada there’s no T2, that being the old CI-4 Plus grade still offered in the U.S.

The new Rotella T5 synthetic blend 10W-40 and 10W-30 are said to offer increased protection and value, and Shell claims they deliver better fuel economy than conventional SAE 15W-40 oil. A large fleet trial earlier this year demonstrated that trucks using this lube showed a 1.6% improvement in fuel economy, the company says.

There’s also and a new performance claim for Shell Rotella T Triple Protection, said to have shown a 22% reduction in engine wear in recent tests.
