AMSOIL Products for Diesel Marine Applications

Engine Oil

AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil (PCO) provides the ultimate in diesel engine protection. Specifically formulated for long-life, it resists oxidation and thermal breakdown, retains viscosity and eliminates sludge and varnish formation. Outstanding lubricity provides unbeatable wear protection and maximum fuel efficiency. It contains special performance additives for acid and soot control. Extended drain capability reduces downtime and oil expenses.

AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil (HDD) has a fuel efficient formula for gasoline and diesel engines. It contains the beefiest additive package of all AMSOIL motor oils and delivers better wear protection than other popular diesel oils, effectively reducing fuel consumption. These oils contain anti-rust agents that shield engine metals from water. They are formulated with 12 Total Base Number for dependable, long-lasting acid inhibition and corrosion protection needed in the operation of diesel marine engines. Generally, motor oils average 7 TBN, offering significantly lower corrosion protection than AMSOIL diesel oils.

Fuel Additives

AMSOIL Cetane Boost Additive (ACB) improves ignition, combustion efficiency and power. AMSOIL Cetane Boost also raises cetane by three to seven numbers and reduces white smoke emissions.

AMSOIL Diesel Concentrate (ADF) compensates for the quality variances of different fuels (including biodiesels) and the deficiencies of today’s ULSD for better engine operation. It reduces cylinder wear, retains TBN longer and minimizes soot loading. AMSOIL Diesel Concentrate improves fuel economy and restores horsepower to like new. It is also a fuel stabilizer.

AMSOIL Diesel Cold Flow Improver (ACF) lowers the cold filter plugging point by as much as 20° and decreases the need for #1 diesel fuel that is diluted with kerosene. It contains jet fuel-type deicer to help prevent ice formation in fuels contaminated with water. AMSOIL Diesel Cold Flow Improver is excellent for use with AMSOIL Diesel Concentrate and AMSOIL Cetane Boost Additive.

Fisherman Saves Time and Money

Commercial fisherman Paul Daniels switched his Detroit Diesel 525 hp 12V-71T boat main engine over to AMSOIL Synthetic 15w- 40 Heavy Duty Diesel and Marine Oil and an AMSOIL Dual Gard By-Pass Oil Filter to increase engine life and decrease maintenance.

Daniels had been changing his conventional oil at 250 to 300 hour intervals. With AMSOIL products on board, he conservatively increased his change intervals until he reached his present 2000 hour oil changes with sampling and filter changes at 500 hours.

"We fish three to six days at a time, sometimes trawling 24 hours a day. The engine runs at continuous load most of the time, which is ideal for a Detroit Diesel. But there's no getting around it - we really work that engine.

"AMSOIL Heavy Duty Diesel and marine Oil and the AMSOIL Dual Gard filter have given me the outstanding protection I demand and the extended drain intervals I want. I appreciate the savings in time and money."
