09-18-2015 Recology Samples BEFORE Precision fuel management program

First sample taken 09-18-2015, lots of water and visible dirt in samples pulled from bulk tank. The company was having issues with equipment running rough, and they were spinning fuel filters way more than manufacturers recommended changes. We sat down with the plant supervisor and talked about diesel fuel quality testing. He was happy to hear his diesel fuel problems explained. It has nothing to do with diesel fuel quality by brand. All fuel vendors get the same fuel supplied to the Northwest.  The environment where this client is located has dust, dirt, and water in the air constantly due to the nature of the recycling processes with wood products. Our first goal was to sample the tank bottom and nozzle and share the results. As you can see from above, they had tons of water and dirt in the tank. So we set up to clean the bulk tank, polish the fuel with 1 micron filtration,  then install quality Donaldson clean & dry filtration including a 4 micron particulate filter, a water filter, and a desiccant breather trap to control the moisture that accumulates in most all bulk tanks. The client had dirty diesel fuel filters that were only 30 micron, letting all the damaging particles right into the equipment.

The second round of samples after the tank was initially clean, the process is showing signs of improvement already.

The second round of samples after the tank was initially cleaned, and the remaining fuel was polished with 1 micron filtration. The process is showing signs of improvement after cleaning the tank. The Donaldson Filtration and Hydrotex PowerKleen additive was working on the contents of the tank, and the inside of the tank is being cleaned by the additive. The effects of water that was in the tank, and rust and corrosion showed signs of improvement on the second samples. Both water and rust will continue to be less in volume each time we sample, it is a continuous improvement program. Over time the water and rust goes away or is caught by the excellent Donaldson Clean & Dry filtration and what remains is attacked by the superior quality of Hydrotex PowerKleen additive!


The most damaging particles and water, the ones between 4 and 8 microns,

are being filtered out of the fuel, the one’s we can’t see with the naked eye. Green Transfer After 04-20-20163rd sample

After 6 1/2 months on the Precision fuel management program the ISO count is well below the manufacturers specs for ANY of Recology's equipment. The water PPM if only 42 down from 89, well below ASTM standards. THESE NUMBERS DON'T LIE, THE PROGRAM WORKS!!!

After only 3 months on the Precision fuel management program the ISO count is well below the manufacturers specs for ANY of the customers equipment. The water PPM (Parts per million)  is now 42 down from 89, well below ASTM standards. THESE NUMBERS DON’T LIE, THE PROGRAM WORKS! To maintain this quality consistently the client only needs to change the filtration when the filtration gauges jump 10 PSI over normal flow rate. The Desiccant breather which controls moisture, has an indicator that turns RED from it’s original YELLOW to let you know it’s time to change.  The Hydrotex additive will continue to make the water drop out of the fuel, keep cleaning the rust and corrosion in the tank, and help with lubricity for the equipment that fuels from the tank.

Dont Wait until you see this

Another customer of ours was having issues with their previous fuel vendor, I approached the operations manager and let him know that we had a program that could turn their fuel issues around. He agreed to let me take bottom and nozzle samples from his tank, the results came back un-readable, meaning there was so much dirt and water that you could see it with the naked eye, (not good). All the damaging particles are between 2 and 8 microns. If you can see visible particles and water you know you are in trouble. We recommended our Precision fuel management program including cleaning the tank and using Donaldson Clean & Dry filtration along with Hydrotex PowerKleen additive and our Star Oilco Premium filtered diesel. Within 3 weeks the client saw results.

“The latest nozzle sample is looking very good, will continue to get down around 14/13/11”. In just one week after the second sample the water ppm has dropped to 52, which is well below the goal of 80 ppm. It dropped 20ppm after only one week of Hydrotex PowerKleen additive making the water drop out of the fuel.

The API gravity is down to 35.9, which means more BTU’s (heat transfer) meaning better gas mileage and horsepower. The fuel is burning clean and dry, like it is supposed to.

The client said, “We have not been spinning filters as often as we were in the past, we see an overall improvement in fuel quality since starting the Precision fuel program with Star Oilco.” Look at the before and after data below from the labDiesel Fuel Tank Testing and Cleaning Portland

If you suspect you have fuel issues because you’re seeing:

  1. Fuel filters plugging
  2.  Trucks and equipment are running rough
  3. Poor engine performance and fuel mileage below normal
  4. Fuel injector issues, pitting scaring or blown out tips

You may have issues with your bulk tank and filtration on the tank.

We can help you with a complementary lab sample test like you see above.

Testimonial #1 Recology North Plains

Recology Material Recovery helps reduce the amount of waste entering Oregon’s landfills. In achieving this goal they strive to seek out new ways, types, and procedures to recycle waste which would otherwise be sent to the landfill instead of reusing it.

The environment onsite is dusty from the recycled wood products and has particulates floating in the air constantly. The piles of debris are kept semi-moist to help keep the dust down, which creates another issue for them to deal with. Both water and particles find their way into the bulk storage tank that they use for diesel fuel to fuel equipment. What seemed like small amounts of dirt and water was being sucked in through the open vents on the tank.

This in turn created issues with their bulk fuel tank cleanliness, their loaders, dump trucks and other “off-road” equipment they use to move the waste products through the recycling process. This picture is a before picture showing a bottom sample from the bulk tank.

Star Oilco suggested putting Recology on our Precision fuel management program. The program tackles the problem at the root cause and corrects it through the following processes:

  • Clean the tank and remaining fuel using 1 micron filtration
  • Install a Donaldson Clean & Dry Filtration kit™ on the tank.
  • Deliver Star Oilco Premium Diesel with Hydrotex PowerKleen™ additive.
  • Star Oilco then monitors the tank over a period of weeks for cleanliness taking bottom fuel samples as well as nozzle samples and sending them to our partner Hydrotex lab in Dallas Texas.

Nick Olheiser is the plant manager of the Recology North Plains and is very happy with the results.

“We do not have to change our filters on our equipment as much as we were”

“We are noticing our equipment is running smooth again since making the changes”

“I am very happy with the results and recommend it to anyone having issues with bulk fuel”

Testimonial #2 Green Transfer & Storage

Green Transfer hauls and stores steel products in N. Portland, they were experiencing issues with the fuel they were getting from a local competitor. Star Oilco took fuel samples from the tank, and also took a fuel filter off the tank and had it sent to labs in Dallas Texas (Hydrotex) as well as Minneapolis, (Donaldson) the conclusion was as follows:

“The primary cause of filter plugging is believed to be a combination of the extremely high levels of glycerin and the polyamide chemistry that has been associated with some cold flow improvers. LCMS also identified DDSA and long chain amines; they are also known to cause filter plugging.” 

What that means in layman’s terms is the fuel had contaminants and particulates that were getting through the filtration and into Dave’s trucks. They were having issues with filters plugging and engines running rough. They were also seeing issues with fuel injectors showing signs of scoring and pitting.

Dave decided it was time to take action and had his tank cleaned, and had the Donaldson clean & Dry™ filtration installed. Dave opted to put an additional pre-filter before the two Donaldson filters, an added step to pre-filter the filters. Dave said,

“Since we re-cleaned the tank and added pre-filter I have not changed any filters. I have not had any other issues or driver complaints”.

Dave had several trucks in his fleet that kept changing fuel filters more and more frequently until they changed to the Donaldson Clean & Dry™ filtration kit and implemented the “Precision fuel management program” exclusively through Star Oilco, Hydrotex and Donaldson.

Star Oilco diagnosed the problems, took the necessary steps to alleviate them with the essential solutions.

  • Clean the bulk tank
  • Install Quality Donaldson Clean & Dry Filtration™
  • Deliver Star Oilco premium diesel with Hydrotex PowerKleen™ additive
