Mobil Delvac 1™ ESP 5W-40
High performance heavy duty diesel engine oil
Mobil Delvac 1™ ESP 5W-40 is a synthetic, heavy
duty oil suitable for a range of US-style marine
applications. These include selected deck
generators, lifeboat engines onboard ocean-going
ships, and main engines of harbour craft and high
speed ferries, dependent on API rating and fuel
The oil is recommended for US-designed low
emission engines, including those with Exhaust Gas
Recirculation (EGR) and after-treatment systems
with Diesel Particulate Filters (DPFs) and Diesel
Oxidation Catalysts (DOCs). It is designed to
protect engines operating in both high and low
speed/high load conditions.
Mobil Delvac 1 ESP 5W-40 is suitable for a range of
engines including ones made by Detroit Diesel,
Deutz, Mack, MAN, MTU and Volvo.
Positive performance under
extreme conditions
Mobil Delvac 1 ESP 5W-40 provides excellent
performance under the most severe operating
conditions. It offers:
•Exceptional protection against soot-related
viscosity, reducing component wear
•Outstanding wear protection, reducing engine
scuffing and bore polishing
•High performance at significantly higher
temperatures than other diesel engine oils
Cleaner engines
Outstanding thermal and oxidation stability helps
to reduce low temperature sludge build-up and
high temperature deposits. This offers vessel
operators the potential for cleaner engines, longer
component life and up to 10 times longer drain
intervals compared with mineral-based alternatives.
Longer service life
Mobil Delvac 1 ESP 5W-40 is engineered to improve
equipment reliability, helping maximise component
life and lower operational and maintenance costs.
This includes:
•Excellent low temperature properties protect
against start-up wear
•Outstanding resistance to corrosion extends life
of critical wear surfaces
•Component compatibility to support longer
gasket and seal life, as well as extended service
•Enhanced BN quality reserve leads to deposit
control and extended drain periods
•Advanced detergency and dispersancy abilities
help promote longer component life
Lowers overall operating and maintenance costs
Compared with conventional oils, Mobil Delvac 1
ESP 5W-40 reduces oil consumption, provides
improved fuel economy, reduces waste oil disposal
and lowers overall operating and maintenance costs.
