The Oldsmobile Omega engine lineup focuses on dependable gasoline power. A 5.0-liter V8 paired with an automatic transmission delivers strong acceleration and smooth cruising, especially for highway merging. A 4.1-liter inline-six offers a balanced blend of efficiency and everyday usability. Both send power to the rear wheels, giving the sedan a classic, predictable driving feel.
