Customer Testimonials: 

Mooney Boats
“We have seen a reduction in fuel consumption, our vehicles are running smoother with no smoke".

Chief Engineer Antartica
"I have been using MarShip DieselAid products during the last fishing season.  We had the diesel bug, it has been killed and has not returned.  The engines are running smoother.  We installed the dosage pump which makes the DieselAid cost efficient.  I will not go to sea with out having the MarShip DieselAid on board."

Nick Fox - Owner FV Green Eye
"I have been using DieselAid LDB to prevent carbon build up on the injectors and to prevent diesel bug. Since using the additive, we have had no diesel bug and after 8000 hours on the engine, it's running smoothly"
