Frequently Asked Questions
What is Delo oil and who makes it?
Delo is a line of heavy-duty engine lubricants made by Chevron. The name stands for "Diesel Engine Lubricating Oil." Introduced in 1935, Delo is engineered for superior protection in both diesel and gasoline engines, and is a trusted choice for marine, commercial, and off-highway applications.
Is Delo oil suitable for marine diesel engines?
Yes. Delo motor oils are well-suited for marine diesel engines, including both two- and four-stroke applications. Products like Delo 100 SAE 40 are specifically recommended for marine use, while Delo 400 series oils cover a wide range of four-stroke diesel and gasoline engines operating under severe conditions.
What is the difference between Delo conventional and Delo synthetic oil?
Delo conventional motor oil uses advanced additive technology to control deposits, sludge, and oxidation in older engine designs. Delo synthetic oil is formulated for newer, low-emission engines equipped with advanced emission control systems such as Diesel Particulate Filters (DPF), Selective Catalytic Reduction (SCR), and Exhaust Gas Recirculation (EGR) — where tighter tolerances and longer drain intervals are required.
Which Delo oil viscosity grade is right for my engine?
The right viscosity depends on your engine's OEM specification. SAE 30 and SAE 40 grades suit older four-stroke diesel and gasoline engines. SAE 15W-40 is the most widely recommended grade for modern diesel engines and offers improved cold-weather pumpability. Consult your engine owner's manual or contact Fisheries Supply for guidance specific to your application.
Can Delo oil be used in both diesel and gasoline marine engines?
Yes. Delo 400 series oils are mixed-fleet formulations, meaning they are suitable for use in both four-stroke diesel and four-stroke gasoline engines. This makes them a practical single-oil solution for vessels with multiple engine types or for operators managing a mixed fleet.
Does Delo oil protect against deposit buildup and sludge in marine engines?
Yes. Delo oils are formulated with advanced detergent and dispersant additives that control piston deposits, disperse soot, and minimize sludge formation. This helps reduce oil consumption, protect turbochargers, and extend engine overhaul intervals — important factors for marine engines operating in demanding conditions.
