Fuel Quality Deteriorates Faster than you Think

Studies carried out by the University of Idaho conclude that the contamination and degradation process of stored diesel is well underway  within 28 days with fuel showing 26% degradation at this point.

These videos courtesy of world leading chemical company Lubrizol, demonstrates the affects low-sulphur diesel has on your engine and how additives can help to control the effects so preventing additional wear & tear on your engine.

Diesel Fuel Treatments & Additives Specifically
for all Diesel Engines

Lower Levels of Sulphur Are Having an Effect on Diesel Engines

Low sulphur diesel is responsible for a range of problems over many sectors including, but not limited to, Marine, Agriculture and Quarries. From leisure users, farmers, work-boat and large container vessels, it affects us all.  At MarShip UK we work with two of the leading chemical additive manufacturers who supply the world’s major oil companies.  Our DieselAid range of treatments are aimed at addressing specific fuel problems as opposed to the commonly promoted catch all, where you could well be buying chemicals that you don’t need.

DieselAid D

Deposit Control - DieselAid® D
Email us for more information Click for Product Data Sheet

DieselAid D is a detergent additive to remove and prevent lacquering or IDID formed from Ultra Low Sulphur Diesel. With ultra fine tolerances found in electronic fuel injectors and common rail systems, fuel delivery is critical to maintaining fuel economy and emissions control. IDID is now a very real issue causing fuel pumps and injectors to malfunction, in some cases within a few hundred hours of running. By maintaining cleanliness in the fuel system, specific fuel consumption is maintained and time between overhauls can be increased. DieselAid D can help with fuel change over in ECA’s by ensuring HFO deposits are quickly dispersed.

Available in 1, 5, 25 and 200 litre containers.    Dose rate: 1 litre to 6,000 litres of fuel

DieselAid Lubricity additive icon


DieselAid L

Lubricity - DieselAid® L
Email us for more information Click for Product Data Sheet

DieselAid L is a lubricant only additive to replace the lack of lubricity in Ultra Low Sulphur Diesel. Lack of lubricity causes problems with sticking injectors and high wear in fuel systems. Most at risk are modern high speed common rail engines that rely on the fuel for lubricity. With fuel system tolerances at a few microns and fuel pressure in excess of 2000 bar., it is critical that some lubricity is reintroduced.

Available in 5, 25 and 200 litre containers. Dose rate: 1 litre to 10,000 litres of fuel

DieselAid LD

Lubricity + Deposit control - DieselAid® LD
Email us for more information Click for Product Data Sheet

DieselAid LD is a blend of lubricity and detergent additives combining the advantages of both the above. If fuel is used regularly and not left standing or stored for long periods this is the simplest and most cost effective additive for modern diesel.

Available in 5, 25 and 200 litre containers. Dose rate: 1 litre to 5,000 litres of fuel

DieselAid Stabilizer icon


DieselAid C

Fuel Stabiliser - DieselAid® C
Email us for more information Click for Product Data Sheet

DieselAid C is a diesel conditioning and stabilising additive. Oil Majors add stabiliser to keep fuel fresh for only a few months. Any fuel that is stored of not used for long periods should always be treated with a conditioner to ensure it remains ready for use.

Available in 5, 25 and 200 litre containers. Dose rate: 1 litre to 2000 litres of fuel
1. Lubricity: To replace the lubricity removed from the Ultra Low Sulphur Fuel
2. Deposit Control : To clean and prevent lacquering.
3. Fuel Stabiliser: Oil majors add stabiliser for a storage life of a few months after which the fuel quickly degrades.
4. Cetane Improver: Degrading fuel loses this all important cetane rating which ensures easy starting.
5. Demulsifier: Fuel is hygroscopic (biofuel 30 times more so), a demulsifier ensures water is separated from the fuel.
6. Biocide: To counter microbial attack in stored (standing) fuel from bacteria, moulds and yeasts.
