There are no harmful effects of over treating gasoline and diesel fuel with DurAlt? FC. However, DurAlt? FC benefits do not increase with over treating.

No. Oregon Administrative Rules requires that an official sample be obtained from the source of the fuel such as directly from the dispenser nozzle.

The use of DurAlt? FC is recommended in each tank of gasoline or diesel fuel used in the vehicle's engine. Yes. DurAlt is completely soluble in all oil based additives, such as stabilizers, anti-gels and fuel conditioners. Yes. DurAlt? Fuel Conditioner has been beneficially used in conventional diesel fuel for many years. DurAlt Technology accelerates the combustion process and significantly reduces the smoke and particulate emissions from diesel engines.

Yes. You will need to contact a motor fuel laboratory, collect your sample according to their instructions, and get the sample to their laboratory all at your own expense and risk.

Call us immediately (503-986-4670) so that we can obtain a sample of the fuel as soon as possible from the same dispenser that you bought your fuel from. Thousands of gallons of fuel are dispensed through modern fueling sites today and multiple refilling of the storage tanks occur frequently. It is very difficult to get the very same fuel that you bought. Ask for motor fuel quality complaint form from our office, complete and mail it back to us as soon as possible.

There are several ways water can enter into the fuel storage tanks. Most storage tanks are under ground and the fill pipe is at ground level, closed with a tight fitting cap, and is covered by a protective lid. Water can seep in around the gasket of the cap or through the spill valve. Water may also be inadvertently brought in with a delivery of fuel to the tank. Or there may be a loose fitting around the top of the storage tanks that allows high ground water to enter the tank.

No. You do not pay the diesel fuel tax when purchasing dyed diesel fuel. However, dyed diesel fuel should only be used to operate vehicles or equipment off-highway. You will be subject to the tax and a penalty if you operate a motor vehicle on a highway in California with dyed diesel fuel in the supply tank. Yes.

Comparing Gasoline and Diesel can be like comparing apples and oranges. In other words, these are two petroleum fuels with distinct applications that can not be compared easily. In general, diesel has more Particulates and Nitrous Oxides pollutants than gasoline (new post-combustion particulate traps can reduce particulate emissions beyond those of modern gasoline vehicles).

Because of the type of fuel as well as the design of the engine itself, a diesel engine operates at lower internal temperatures. This helps lengthen the lifespan of the engine block. In addition, there are no spark plugs and associated ignition parts, which reduces maintenance. A diesel engine also has fewer moving parts, which also helps increase engine life as well as reduce maintenance. And, diesel fuel is often less expensive at the pump than gasoline.

Because of the way diesel engines are built they will last many times longer than a gasoline powered engine. Diesels are far more efficient, as well. Though the energy used by a single light is small, if you use energy-efficiency practices with all your lights, the savings can add up. To reduce your lighting costs, consider: Installing controls such as timers, time clocks or photocells to ensure that exterior lights are turned off at the appropriate time.

The fuel produced at the refinery will be distributed to those markets it can supply most cost-effectively – primarily in the Midwest. Currently the Midwest region imports well over one million barrels of refined product a day from Gulf Coast region refineries.

You may submit your refund claim and registration application at the same time, though the registration process may slow the handling of the claim. In addition, you will be asked to submit a completed Diesel Questionnaire.

There is no difference between fuel (heating) oil and off road diesel. However, road diesel has lower sulfur and is clear. Heating Oil and off road are dyed.

There is no definition of premium fuel, so the term eally means nothing and is over used by suppliers. For a descrition of the characteristics proposed for "premium diesel" see this Cheveron bulletin. Cummins says that fuel additives are not needed in their engines.

Emissions results do vary between engines and test equipment, but in our tests on an early 80's VW turbodiesel, opacity (which is used as an indicator of particulate emissions) was reduced by about 50%, compared to premium diesel fuel. Other EPA regulated emissions were about the same for all the fuels tested. Power was equal to premium diesel that test. We find no difference power while driving, between diesel and SVO/WVO, as long as the filter is clean and the SVO is heated.

Well, you could mix it yourself (as mentioned earlier), but there is a company in California called Aero Dyne who sells pre mixed diesel in small, or large quantities for a very reasonable price--and how I wish I could buy their fuel here :-(

Yes, The EPA has finalized similarly stringent standards for non-road diesel fuel that will be phased in over several years. In California, there is no distinction between on-highway and off-highway diesel fuel. The 2006 California diesel fuel regulation will cover off-highway diesel as well.

Sulfur content, Cetane number (ignition quality), cleanliness, lubricity, low-temperature operability and stability are the diesel fuel requirements of principal concern to you. With the introduction of the 2007 model year, diesel powered vehicles have to meet stringent emissions limits. The equipment used by vehicles to meet those standards depend upon a fuel with very low sulfur content, 15 parts per million (ppm) or less, referred to as Ultra Low Sulfur Diesel (ULSD).

Ultra Low sulfur diesel fuels (less than 15 ppm) are required by federal regulations for 2007 model year highway vehicles to ensure that these vehicles will meet emissions standards to improve the quality of the air we breathe. In California, other properties of vehicular diesel fuel are also controlled to help reduce smog.
