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 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 by-pass filter give me the outstanding
protection I demand and the extended drain intervals
I want. I appreciate the savings in time and money.”
