Delo® 1000 Marine Marine Engine Oil – Reliable Power for Every Operating Hour

In an increasingly demanding maritime industry, trunk piston diesel engine oils must meet numerous stringent requirements. One of the most critical needs today is a diesel engine oil capable of maintaining engine cleanliness, minimizing wear, and ensuring consistent performance throughout the operating cycle.

Delo® 1000 Marine is the trusted solution, designed specifically for medium-speed trunk piston engines using distillate fuels with sulfur content up to 1.5% in marine applications.

Optimal Protection – Sustained Performance
Helps maintain engine power output thanks to an advanced detergent and dispersant additive system that effectively controls high-temperature deposits on components such as piston undersides and ring belt areas.

Extended Oil Life – Reduced Wear
With a stable Base Number (BN) and excellent retention capability, Delo® 1000 Marine helps neutralize corrosive acids formed during the combustion of sulfur-containing fuels, thereby reducing cylinder liner wear and significantly extending oil service life.

Superior Water Separation Performance
Another major advantage of Delo® 1000 Marine is its effective water separation without additive loss, helping maintain centrifugal filtration performance under harsh operating conditions.

Versatile Applications
Suitable for medium-speed diesel engines using distillate fuels in marine vessels (main or auxiliary engines), and trunk piston engines without crossheads using distillate fuels in power generation plants.
Compatible with marine reduction gears requiring the same type and viscosity grade of engine oil – do not mix with EP gear oils.
Can be used in stern tube systems requiring engine oil of the same viscosity grade – avoid mixing with compounded oils.

Usage Considerations

• Base Number (BN) Selection
Lubricant selection should align with engine manufacturer recommendations, fuel characteristics, and application severity. Using an oil with a BN lower than required can cause rapid corrosive wear. Conversely, a BN significantly higher than the sulfur content in the fuel can lead to ash deposit buildup on exhaust valves, potentially causing damage.

• Oil Filtration System
Engines typically use centrifugal and self-cleaning filters to remove combustion-related deposits. Therefore, trunk piston engine oils (TPEO) are formulated to suspend deposits and remove them via filtration while retaining detergent and dispersant additives. TPEOs differ from automotive or locomotive engine oils – they should not be interchanged.

To maintain effectiveness, the additive system must be properly balanced. Adding fresh oil to a system with high contaminant levels may disrupt this balance, especially if filtration performance is compromised. It is recommended to check oil levels daily and maintain at least 95% of tank capacity.

Introducing oil with different characteristics may interfere with dispersant functionality. Oil changes should be carefully managed. Water can be removed via centrifuge without additive loss, but oil should not be water-washed.

Some medium-speed engines, such as Glacier types, lack advanced filtration systems and rely solely on centrifugal filters. In these cases, oil must suspend deposits until removal. Standard TPEOs are not suitable for such engines – specialized oils should be used according to manufacturer instructions.
