What is Clean Diesel? 

Clean diesel is free of the contaminants that harm modern diesel engines. Today, there is a gap between ASTM diesel standards and the ISO cleanliness standards needed for use in high pressure common rail engines. Anyone operating a modern clean diesel engine is seeing the effect, including injector replacement, DPF regeneration, and a host of other fuel quality related maintenance concerns we never saw twenty years ago. On top of all of that, today’s refined diesel fuels are less storage stable than ever before. What is on the bottom of your bulk tank can also complicate matters further. When diesel is bought wholesale, it typically meets and exceeds ASTM required industry standards, but almost always requires additional filtration to avoid excessive engine wear and premature part failures.

Having clean diesel requires an additional amount of care. Namely, you need to make sure that the fuel is aggressively filtered at 4 microns to catch the microscopic particles that are big enough to damage your modern diesel engine’s high pressure fuel rail system. Furthermore, clean diesel is fuel that is free of water and stabilized with Premium Diesel to guarantee no bacteria, yeast and other creatures can grow and further contaminate the saddle tanks on your trucks.

For more on clean diesel, see Donaldson’s description of “The New Clean” for an in-depth explanation of what ISO cleanliness and filtration mean for your diesel fleet.

Making Diesel Cleaner!

Knowing the quality of your fuel is the first step. This is done by taking samples off of the bottom of your bulk storage, as well as a representative sample from your fuel dispenser. Lab tests of those samples will tell you if you have water, biological growth, or dirt issues with your storage. The contaminants in the tank being sampled are almost always visible, which is to say that they look horribly ugly. If your fuel quality assurance has been on autopilot, do not be surprised if you find this. After gathering knowledge about your fuel, the next step is to get your fuel quality clean.

Filtration and tank bottom sampling is the start. Beyond that, the only way to improve your fuel quality performance is to filter your fuel, ensure water is not getting into the tank through condensation, and additize it with a Premium Diesel additive to upgrade the performance of the fuel. Many fleets today are seeing injector wear and continual problems with particulate trap maintenance. This is a combination of water in fuel and microscopic particles not captured by a 10 or 30 micron filter used at most diesel dispensers. You have to filter more aggressively than this.

Clean, Dry, and Premium Diese

Where To Start?

The first step is sampling your bulk diesel tank. We check your bulk tank for water and dirt to make sure and meet the specifications your engine is built for. Star Oilco can help by providing a complementary diesel test for those fleets interested in taking control of their fuel quality assurance. Usually when testing fuel, we take a sample off of the tank bottom as well as a representative sample out of the fuel dispensing nozzle.

What we usually find is ASTM specification diesel fuel (it meets ASTM spec) that is higher than you’d want (still in spec) for water with far more dirt than the OEM’s would want to see in your engine. This dirt fails to be within the “ISO Cleanliness” specifications recommended by engine manufacturers. Usually, we also see water on the bottom of the fuel tank, which is a likely source for future or current biological growth in your fuel tank.

Star Oilco can help you fix this! The first step is to sample your fuel tank.

NOTE: If you have a current biological growth problem in your bulk fuel tank or fleet, your first step is to treat that effected fuel with a diesel microbiocide to kill the bugs growing in your tank. For more on this, see our Valvtect Plus 6 Diesel Microbiocide page.

Call Star Oilco to get your diesel tested. 

This winter, Star Oilco is offering complementary diesel fuel testing for any fleet operating in our service area. We are providing fuel quality testing in partnership with Hydrotex to assist fleets in our area struggling with containing the cost of fuel related maintenance.  Typically a diesel lab test costs over $200 depending on the lab.  Don’t let the hurdle of a scientific analysis stand between you and full knowledge of what is effecting your fleet.

Since the move to Ultra Low Sulfur Diesel in 2007 along with moving changes in diesel refining and biodiesel mandates fuel quality has been a moving target.  More importantly petroleum refiners and distributors follow an ASTM specification for diesel which is not as stringent as the ISO standards demanded by OEMs making the trucks on the road today.  Water and dirt in fuel are robbing your fleet of money.  Get a handle on it and move forward armed with that knowledge.

Star Oilco and Hydrotex can help you understand what is going on, what the quality of your tank bottom is, and what you need to do to reduce the cost of operating your fleet as it relates to diesel fuel.

Call Star Oilco and state you want to get your fuel tested for both ASTM and ISO specification. A member of our team will help you take the sample off of the bottom of your tank as well as from your dispensing nozzle.

Fuel Filtration-Clogged Filters-Cleaning Them Up.

Has your fleet experienced black diesel fuel or clogged fuel filters?  
Do you wonder what makes diesel go bad or cause further issues?  

contaminated_diesel

In most cases, it’s water and dirt in the fuel leading to further degradation over time. If gone unchecked it will lead to mechanical failures in your fleet.

 

Donaldson Filter has a great educational video about the high stakes importance of aggressive filtering of your diesel prior to going into your fleet. Today aggressive filtering and ongoing quality assurance of your fuel is a must. Star Oilco calls this Precision Fuel Management and we offer it to all of our bulk fuel customers.

Precision Fuel Management is the ongoing improvement of your diesel fuel quality.

This is done by adding aggressive Donaldson filtration to the dispenser on your diesel tank or filtering fuel on Star Oilco’s Mobile Onsite trucks when wet hosing our customers). For bulk storage tanks, we include a Donaldson desiccant breather to the vent on your tank to scrub moisture from the air as it is pulled into your tank, as well as Hydrotex PowerKleen Premium Diesel Additive. In addition to these best practices Star Oilco will also sample your tank bottom, as well as take a representative sample out of your diesel nozzle and lab test this fuel according to the ULSD ASTM standard D975, as well as check for the ISO cleanliness level of your fuel. We test twice a year going into Summer and Winter to confirm if there is water on the bottom of your tank as well as any worries about dirt, biological growth, or any other recurring, but preventable fuel quality problems.

NOTE: ASTM D975 is the specification for ultra low sulfur diesel in the United States. ISO Cleanliness is a standard to check for microscopic dirt that can harm the performance of your engine systems long term if it’s getting past your engine filtration.

Diesel technology has advanced a long way in the last decade to meet the extremely high emission standards of the EPA and CARB for diesel engines. What this advanced diesel tech means is that your engine has extremely high-operating fuel pressures and extremely tight tolerances for the fuel acceptable to the long term use of your engine.

What does this mean in a nutshell?

High operating fuel pressures and tight tolerances in the fuel rail mean dirt and water can destroy injectors and affect the operation of your fleet. These two contaminants (dirt and water) are the source of most other fuel-related problems and therefore your highest exposure to preventable maintenance cost. If you have experienced unexplained fuel filter spinning, failed injectors, and DPF maintenance that is more than normal, it may be fixable with Precision Fuel Management.

Precision Fuel Management is aggressive filtration at the fuel dispenser combined with PowerKleen Premium Diesel and a clean dry tank bottom that is sampled and tested regularly. If you want to look into cleaning up your bulk fuel, give Star Oil a call. Our first step is a complementary test of your fuel.

If you have an immediate concern about biological growth and long-term storage with your diesel, we recommend an alternative stopgap measure. Treat your fuel with Bioguard Plus 6 to kill the bugs growing in your diesel fuel.

Fight Humbug in your Diesel Tank!

Fall weather is around the corner and moisture is depositing in your diesel tank.

Treat your diesel; keep things from growing in your diesel.

Prepare your diesel fuel, heating oil, kerosene, or boiler fuel for storage.

Make sure your fuel works when you need it. If you have a bulk diesel tank, stop stuff from growing in your diesel before it starts.

Star Oilco provides complementary diesel fuel quality testing for tanks in our service area.

Valvtect BioGuard Plus 6

Valvtect Plus 6 – Stabilizer and Biocide

Use every spring and winter to guarantee your tank is not providing a habitat to fuel system spoiling microbes.

Water in diesel is a fact of life these days. Biological growth spoiling your fuel quality does not have to be. Ultralow sulfur diesel and biodiesel have water in them. Over time, water entrained in your diesel fuel can fall out of solution. Add to that they condensation that will natural develop in your fuel tank and you have an environment for hum-bug to grow in your heating oil, diesel, or boiler fuel storage tank.

 

If you are storing diesel for longer than six months you want to stabilize that fuel.

In the summer when temperatures swing at night, your tank is breathing air in and out.  If it is raining, your tank is likely also breathing in the water. With the rainy season and long after it passes, be aware that water is everywhere unless you work to seal it out of your fuel storage system.  You can use a desiccant breather as a way to filter moisture from the atmosphere from getting into our tank.

If your tank does not have a desiccant breather on it, your fuel tank can collect condensation. As air moves in and out of the tank with temperature changes, moisture will collect on the wall of the tank. Yeasts, bacteria, fungi, and algae can grow in that water which collects on the bottom of the tank. Make sure your tank is not a habitat for growing bugs every spring and winter.

Microbiological growth in diesel fuel, also known as “humbug” in fuel, can start growing and if unchecked, will wreak havoc with your fleet. Once it starts in your fuel tank it will spread throughout your fleet. If you see a random need to spin filters between services or odd fuel-related maintenance issues, you likely have bugs growing in your fuel tanks.

Star Oilco recommends BioGuard Plus 6 as a regular biocide for routine maintenance.  

BioGuard Plus 6 is the only EPA certified biocide product that has both a biocide as well as a fuel stabilizer with detergent in one product. This detergent stabilizer acts as an aggressive tank cleaner (NOTE: BioGuard available without Plus 6).

When using Valvtect BioGuard, treat first with a kill, done in your bulk diesel storage. That will spread and kill the growing bugs in your fleet. Maintenance will clean up any remaining bacteria. If you do not have a known or seen problem, a kill twice a year is a great way to guarantee it does not appear and treat the individual tanks of your fleet.

Fixing the problems with bugs growing in your diesel

What to do about Biological Growth in Diesel Fuel.

Fuel Marketer News has two great articles on biological growth in fuel tanks. Star Oilco as a diesel fuel delivery provider in Oregon and Washington is all to familiar with this emerging problem with ultra-low sulfur bio-diesel blend fuels.

Where there is water, bugs can grow in diesel.

The Fuel Marketer News articles below:

Fuel System Bugs Drain Revenue, and
Bugs Cause Fuel System Damage (part 2)

These articles in a nutshell are about the costs, impact, and ongoing effect of bugs growing in fuel as a real industry issue. If you have filters clogging in your fleet–much like a heart attack–it’s not a symptom, it’s a late-stage problem. Clogged filters slow down your fleet fueling and add serious cost to your vehicle maintenance. Lost power on the highway also slows your drivers down, escalating the drain on efficiency fuel that bugs may be causing.

Star Oilco can cure these problems, both with stopping hum-bug growing in your diesel tanks, as well as ensuring that the water those fuel bugs live in stops migrating into your tank. We will help you solve diesel fuel quality issues.

The first step is for Star Oilco to test the bottom of your fuel tank, as well as take a representative nozzle sample that would go into your trucks. We will show you where your fuel quality is today and come up with a collaborative way to move that into exceeding ASTM diesel specification, as well as aligning with engine manufacturer’s ISO specifications for diesel fuel cleanliness.

If you have questions about fuel quality assurance, Star Oilco has solutions. Left unattended, your diesel fuel will grow bugs, alga, yeasts, and other biological active destroyers of fuel quality. If you need to treat your fuel to kill humbugs like these, Star Oilco recommends Bioguard Plus 6 as your go-to solution. It is both a biocide that kills the bugs growing in fuel, as well as a heavy duty detergent to clean up other deposits as well.

Tier 4 Engines and Diesel Contaminants – Donaldson White Paper 683 1024 Star Oilco

Tier 4 Engines and Diesel Contaminants – Donaldson White Paper

Managing bulk diesel fuel storage has become more complex in recent years. Especially in Oregon and Washington the chance of water finding it’s way into your fuel tank is a real concern. If water gets in your bulk fuel biological growth or “hum bug” won’t be far behind.  Donaldson has positioned itself with real concrete solutions for for fuel quality.

With the extremely tight tolerances of today’s clean diesel engines and the expansion of sour crudes from tar sands, oil shale, and other source being hydrocracked into today’s ultra low sulfur diesel we have all seen it.  Fuel quality has stayed the same while the tolerance engine manufacturers build to have gotten tighter.

To help fleets solve the fuel quality issues fleet’s are dealing with these days Donaldson Filters has put out an intensive white paper on the what clogs filters.

Titled “Analysis and Identification of Contaminants in Diesel Fuel Filtration and Storage Systems” it goes into a level of depth of what the causes of filter spinning in your fleet is. If you are seeing clogged fuel filters this can help you diagnose and begin to problem solve for your fleet.

Usually diesel engine maintenance costs spin out of control around injector failure, DPF maintenance down time, and recurring regen cycles at the most inconvenient times blowing white smoke everywhere.  Usually this fleet management pain point revolves around dirt and water in diesel fuel.  Problems that Donaldson Filtration is the industry leader in solving.  Aggressive filtration and desicant breathers on tanks will polish your fuel beyond the low standards of petroleum standard ASTM and will exceed the ISO cleanliness standards the OEM’s made your engines to run.

This document is designed as and essential review of diesel contamination as it’s seen from the perspective of a filtration company guarding your diesel engine systems from problems.

This matters as the current generation of clean diesel technology commonly called “Tier 4” engines have a tighter specification need than industry standard diesel specification will meet in practice in the field.
