The investment you have made in your boat is significant. You have outfitted it with electronics, life-saving equipment and all the creature comforts of home. You probably have your diesel engine regularly maintained by a qualified marine diesel technician and may carry an engine spares kit onboard.

Fuel treatment for microbial contamination, preventive fuel tank hygiene measures and year-round engine performance improvement may be the most important aspect of boat maintenance – yet is regularly overlooked – until a major problem occurs. Power Service manufactures biocides, water dispersants and performance additives to meet the highest operational and performance standards of the marine diesel industry. Don’t get stranded out at sea. Trust your diesel engine to Power Service.
