I put this information together by editing a Cummins Bulletin covering the use of Fleetguard injector cleaner.

Hope it helps owners of a different manufactures diesel engines get an understanding of why one needs to use an injector cleaner and how it helps to maintain engine performance.

You may have an engine built by a different manufacture, requirements and preferred products might very. So one should fallow the procedure set forth in there owners manuals and there preferred product.

When one decides to run this procedure a little for planing would be good. For me it would be driving from the Northeast to Florida and stopping at Gaffney, SC, Freightliner service to have the filters changed. Millage and hrs. work out right.

In regard to the Diesel Generators using the same fuel source. The injector cleaner will go through that engine as well and will clean its injectors. The fuel filter could be effected the same way as listed below, in filter changes. The fuel amount and running time is less in most cases, but in hot weather when one is running it to power and AC units. The greater the running time, the greater the effect on this filter.

Note! there is a chart included with this information and they do not always post or copy well, if this happens I will see if I have enough allotted space to attach a PDF copy of the information.

Diesel Fuel Injector Cleaner
Removes Deposits and Restores Performance
Fleet Pride Cleaner:
In today's high-performance diesel engines, fuel and other contaminants can combine to form harmful deposits especially when exposed to the high temperatures and pressures associated with advanced fuel injection system equipment. Traditional fuel additives may not be effective in removing or preventing such deposits, which may in turn affect engine and fuel system performance. Including:

Increased white or black smoke

Power loss

Reduced injector life

Reduced fuel economy






Superior Performance
Fleetguard Diesel Fuel Injector Cleaner is an ultra-concentrated detergent additive that uses a technologically-advanced formula to remove traditional and soap-based deposits, which helps restore fuel injector performance.
Designed for year round use, Diesel Fuel Injector Cleaner’s proprietary mixture of advanced additives is specifically formulated to clean fuel injectors. When used continuously, it also prevents new deposit formations thereby enhancing engine performance and maximizing injector life.

Benefits to Your Bottom Line
Diesel Fuel Injector Cleaner provides a wide range of comparative benefits that help reduce maintenance costs and increase vehicle up-time, including:

Restores injector performance

Restores power

Prevents new deposits from forming

Effective on both traditional and ULSD-based soapy deposits

Optimizes Fuel Economy





Reduces white and black smoke

Product Usage Recommendations

Cummins Filtration strongly recommends that an initial treat rate of 1:1000 (see table below) be used for the first 48 hours or 2400 miles (whichever occurs first) under normal operating conditions to ensure injector performance is fully restored. To achieve superior cleaning, the initial 48 hours should not include idle or down time. Diesel Fuel Injector Cleaner is a powerful cleaning agent which removes existing fuel system deposits, asphaltenes and other residue during initial use It is therefore, recommended that the initial 48 hour cleanup is performed prior to a scheduled fuel filter service interval to avoid degradation of engine performance due to the possibility of filter plugging. Following clean-up, a treat rate of 1:5000 should be used on a continuous basis to prevent deposit information. Diesel Fuel Injector Cleaner is fully compatible with all ULSD fuel, #1 and #2 diesel fuels, combination fuels and with after market treatment devices including EGR, DPF SCR





Treatment Ratio
1: 1000 ratio = 1oz. to 7.8 gal., 6.4oz / 50 gal and 12.8oz. / 100 gal.

5: 1000 ratio = 1oz. to 39 gal., and 2.56oz. / 100 gal.


1 qt. 1 gal. 5 gal.
CC36095 CC36096 CC36097
Initial use 1:1000 250 1000 5000
Maintenance 1: 5000 1,250 5,000 25,000

Maintenance
The use of this product does not eliminate the need for hydrocarbon injector/dowser cleaning as required by Cummins Heavy Duty engines with the Cummings Particulate Filter (EPA 07 and later). Please see your owner's manual for more details.

Product Specifications
Diesel Fuel Injector Cleaner is designed to treat bulk diesel fuel storage tanks, as well as vehicle diesel fuel tanks. Simply add the proper amount to the tank first and follow with diesel fuel.

The product was designed by the Cummins Filtration (Fleetguard) Chemical Products group. Before retiring from CF as a field engineer, I worked with the Chem Products group in getting some field testing started. The explanation that there is deposits is accurate. The issue was most notable in High Pressure Common Rail fuel systems that had frequent and repeating injector failures due to the build up of gum deposits that are removed from the fuel system especially since the advent of ultra low sulfur diesel fuel. That fuel is easily capable of removing old gum deposits from every surface it comes in contact with. This would include the pipelines, tank farms, vehicle fuel tank and fuel lines.

The importance of the initial treat rate is to provide an intense cleaning of the surfaces within the system. Removal of those deposits has been known to cause filter plugging. It would be a good idea to carry spare fuel filters when doing the initial cleaning.
