Bulk Fuel

We have daily routes for diesel fueling in Portland, Oregon and Vancouver, Washington. If you need diesel, kerosene, gasoline, biodiesel, or renewable diesel in bulk or as a wet-hose fueling service, we are ready for your next project.

Keep and make your diesel fuel cleaner

Clean, dry, premium diesel

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 then 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 Diesel!  Where To Start?

The first step is sampling your bulk diesel tank. We check your bulk tank for water and dirt, and make sure to 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.

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.
