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).

A gasoline engine is a stoichiometric engine, which uses an efficient combination of air and fuel for total combustion. It intakes a mixture of gas and air, compresses it and ignites it with a spark (spark ignition). Most gasoline engines run in light duty vehicles such as passenger cars and small trucks. A diesel engine is a heavier duty product designed for work in industrial, automotive, and truck applications.

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.

Depending on your price range, your location and your needs your new or used car choice is not an easy one. For new cars, start your research at the newly posted website of the Department of Energy. Go to "Fuel Economy" for more information. The federal government does give some tax credits for Hybrid gasoline-electric, diesel, battery-electric, alternative fuel, and fuel cell vehicles. Go to "Energy Star" for more on tax breaks for new cars.

Oregon adopts motor fuel standards developed by the American Society for Testing and Materials (ASTM). These are nationally recognized standards and are used by regulatory agencies and industry alike.

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.

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

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.

Both gasoline and diesel fuels are mixtures of hundreds of different hydrocarbons which differ in their chemical structure and composition. During the combustion process encountered in gasoline and diesel engines, these various hydrocarbon molecules mix with oxygen supplied by the air and compete for the combustion reactions in which carbon is converted to carbon dioxide and hydrogen is converted to water.

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.

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.

Gasoline and diesel engines operate according to different engineering principles and burn completely different fuels. Gasoline engines require a volatile, high octane fuel whereas diesel engines run on a low octane and relatively low volatility fuel. Gasoline engines usually operate at higher temperatures and because of their composition and the high temperatures produce entirely different combustion products than does diesel fuel operation.

Yes. However we do recommend the use of an additive free filter on all coolant systems to remove all solid and liquid contamination. Coolant system maintenance should always be done as a complete package to be most effective.

Yes, regular exercise helps lubricate the seals and engine components and keeps carbon from building up. Regular exercise also heats up the generator windings and removes or expels excess moisture. In sets equipped with brushes, exercising helps prevent corrosion build up on the slip rings. It may seem strange that not using a machine could cause performance problems, but with RV generators that's exactly the case.

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.

If I use biodiesel, will it harm my car to go back to petrodiesel? (e.g. in an area where biodiesel isn't available)

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.
