1. Fuel Characteristics Have Changed: Diesel fuel characteristics have undergone numerous changes that can have a severe impact on engine operation and performance. Further changes are being forced by emissions regulations. These changes include restrictions on certain fuel components, such as sulfur. Also with the increases in fuel costs, alternative fuels such as bio-diesel are becoming more prominent.
2. Particulate and Debris in Diesel Fuel: When diesel fuel comes from the refinery, it is clean and free from any particulates. However, as it is transported and stored, dirt and sludge can form which causes problems for engine fuel management systems.
3. Water in Diesel Fuel: Poor housekeeping is probably the largest contribution to water in fuel problems. Water enters bulk fuel tanks via condensation, carryover from fuel distribution systems, leakage through the fill cap, and spill contaminant valve or piping. This can allow significant quantities of water to be pumped into vehicle fuel tanks.
4. Microbiological Growth in Diesel Fuel: Water in diesel fuel can allow certain microbes to grow in fuel. Their waste products contribute to the overall particulate contamination. Particulates become trapped in tank walls, fuel lines and system components. The result is dirty fuel tanks, clogged lines, and plugged piping.
5. Develop and Maintain a Luber-finer Fuel System Maintenance Program: The development of a viable scheduled maintenance program and the use of good quality fuel filters are vital to protecting your investment. Luber-finer offers a complete line of filtration products to maintain and protect your fuel system and equipment investment. If you have questions, please feel free to contact a Luber-finer representative.
1. Know Your Coolant Type: Luber-finer provides coolant filters, supplemental coolant additive (SCA), and coolant test strips for conventional coolant. In addition, we provide Non-SCA filters for long-life coolant.
2. Perform Visual Inspection of Coolant and System: Perform a visual examination of the coolant to ensure that it is the proper color and free from debris, rust and lubricating oil. Drain, flush and refill if visual inspection indicates any contamination. In addition, check to make sure the radiator air intake is free of debris and obstructed air flow. Examine hoses for pliability and ensure that they are a safe distance from hot engine components. Check hose clamps for coolant leakage and proper tension. Also inspect for indications of a faulty radiator cap, which can lead to coolant breakdown and boil over.
3. Perform Testing of Coolant: When maintaining systems filled with conventional coolant, it is vital to check for proper SCA level, pH and freeze point protection. This can be accomplished with the use of all-in-one Luber-finer Coolant Test Strips. Be sure to test engine coolant at each scheduled service interval (20,000 miles) to maintain proper cooling system protection.
4. Treat Coolant with Proper SCA Products: Once coolant has been visually inspected then tested with Luber-finer test strips, proper treatment is required. SCA contains inhibitors designed to prevent generalized corrosion; nitrite for protection against cavitation erosion; scale inhibitors that keep hard water scale from depositing on engine surfaces; and buffering agents to reduce the acidity of the coolant. Luber-finer gives you a sensible, economical way to maintain your cooling system with the proper SCA treatment.
5. Develop and Maintain a Luber-finer Cooling System Maintenance Program: The development of a viable scheduled maintenance program and the use of quality coolant products are vital to protecting your investment.
1. Utilize good, clean, quality fuel.
2. Eliminate possible sources of contamination at bulk fuel-storage facilities.
3. Monitor fuel-storage for water, bacteria or fungus. Treat appropriately with preventive maintenance.
4. Drain vehicle fuel tanks on a regular interval. Remember, this should be done at least 24 hours after the vehicle has been idle.
5. Never use gasoline or alcohol alone as a diesel-fuel additive.
6. Do not blend used oil with diesel fuel. It can cause increased wear of injectors and plug filters, and form carbon deposits on piston tops.
7. To help minimize the condensation and water accumulation in vehicle fuel tanks, top off with fuel at the end of the day.
8. Luber-finer fuel filters are designed to last beyond the recommended change interval. If a fuel filter does not last as long as the change interval, it can generally be attributed to excessive contaminants and/or water. Always remember to drain fuel/water separators periodically.
- Consult with engine manufacturers, your oil supplier and Luber-finer distributor for recommendations.
- Use the correct API certified oil and Luber-finer IMPERIAL XL filters.
- Use a high quality oil analysis program to monitor your engine oil condition at every oil change on all vehicles using the maximum oil and filter change interval recommended by the engine manufacturer.
- Review other maintenance practices to be sure they are being conducted according to recommendations.
