ENGINES OVERVIEW
The Oliver 550 tractor features a 2.5L 4-cylinder engine option available in both gasoline and diesel variants, offering versatility in fuel choice. The gasoline engine provides quicker start times and smooth operation, while the diesel variant is more fuel-efficient and offers better torque for heavy-duty tasks. However, the diesel may come with higher initial costs and maintenance complexity compared to the gasoline model; thus, selecting the right fuel type will depend on specific application requirements and operational budgets.

ENGINE DETAIL 1
The Oliver 550 tractor is powered by a gasoline 4-cylinder engine with a 155 ci (2.5 L) displacement, providing moderate power suitable for general agricultural tasks. With a bore and stroke ratio of 3.62 x 3.75 inches and a compression ratio of 7.75:1, it delivers optimal torque at a rated RPM of 2000, making it effective for implements that require sustained power. The oil bath air cleaner and 4 qt (3.8 L) oil capacity ensure efficient filtration and lubrication, but operators should be aware of the potential for increased maintenance needs typical of older models.
