    The Different Aspects of Cetane

    Cetane is becoming commonly heard, but many people still ask; ‘What is Cetane? Why do I want Cetane?’ Lets consider three aspects of cetane to answer these questions.

      • • 1st, What is Cetane Number?
      • The Cetane Number or CN is a measurment of the length of time from fuel injection until the combution process begins. It is NOT a measurment of fuel economy, power or combustion smoothness.

      • • 2nd, How does Cetane Work?
      • Cetane improvement reduces the ignition delay period between the first fuel injection into the cylinder and start of combustion. In short, the higher CN the easier fuel will combust in a compression setting (such as a diesel engine). The characteristic diesel ‘knock’ occurs when fuel that has been injected into the cylinder ignites after a delay causing a late shock wave. Minimizing this delay results in less unburned fuel in the cylinder and a less intense ‘knock’. Therefore higher CN fuel usually causes an engine to run smoother and quieter.

      • • 3rd, Why do I want higher Cetane in my diesel fuel?
      • By increasing the cetane number of your fuel you improve cold starts and reduce engine noise. By reducing the ignition delay cetane causes a more complete burn, because of this it is very common to see a MPG increase with a higher CN.

    • Generally, diesel engines operate well with a CN from 40 to 55. As mentioned earlier, fuels with a higher cetane number have shorter ignition delays, providing more time for the fuel combustion process to be completed. Hence, higher speed diesel engines operate more effectively with higher CN fuels.
    • Interestingly many countries, such as Iceland, Norway, Switzerland and many other countries in Europe, require a minimum cetane rating of 51. Premium diesel fuel can have a CN as high as 60.
    • The U.S. however, has a minimum CN rating at 40 and Premium diesel fuels are not required to have a higher cetane rating, it is left to the discretion of the supplier.
    • With these facts in mind Opti-Lube provides a number of diesel additives ranging from a 3-9 point cetane increase to help you ‘blend’ your way to premium diesel. See your diesel vehichle running at peak efficiency and grab some higher MPG today with Opti-Lube Diesel Fuel Additives.

    Why Do I Need a Stabilizer?

    When storing diesel fuel, most everyone is familiar with the adverse effects of water or growth in their bulk tank, but are there other factors or elements that cause diesel fuel to degrade? The simple answer is YES.

    The storage life of any fuel is dependent on the storage conditions. Untreated diesel fuel can be expected to stay in a usable condition for approximately 12 months when stored at an ambient temperature of 68°F and 6-8 months when stored at temperatures exceeding 85°F.

    Why? As diesel fuel gets older a fine sediment and gum forms in the diesel brought about by the reaction of diesel components with oxygen from the air. Oxidation eventually leads to fuel darkening and stratifying (layers in the fuel, separation). This sediment and gum will block fuel filters and burn inefficiently in the engine often leading to carbon and soot deposits on injectors and other combustion surfaces.

    The ageing process can be accelerated by the following conditions:

    • Zinc, copper or metal alloys containing them (such as brass) react with diesel fuel to form unstable compounds. This can be counteracted by a metal deactivator which neutralizes the catalytic affect of diesel fuel coming in contact with the metals or metal alloys.
    • Oxidation is another factor to consider. Oxidation is when small amounts of air attack reactive compounds in the fuel, causing it to destabilize and corrode.
    • Corrosion happens due to water and oxidation. The most common form is rust. Eventually rust can cause holes in tank walls but the more immediate danger is contamination in your fuel. These particles can plug filters and increase fuel pump and injector wear in your vehicle.
    • Water in the tank allows the growth of fungus and bacteria, which can cause natural by-products such as organic acids that destabilize the fuel. The main cause of water in fuel tanks is condensation. A simple way to counteract condensation is to keep your tank full when storing for extended periods of time as well as having a defined low point on your tank where water will collect and can be drained (this process can be aided by a water separator, demulsifier).
    • Exposure to high temperatures will accelerate growth in the tank.

    With these factors in mind Opti-Lube created Preserve to help you reach the maximum storage potential of your bulk tank fuel.

    Though diesel fuel will eventually degrade anyway, Preserve helps to delay that. A diesel stabilizer should be added to new diesel as no stabilizer can fix fuel that is already failing.

    When these issues are addressed you can more than double the storage life of your diesel.

    Take the first step towards preventing these common problems from becoming your problem, add Opti-Lube Preserve to your bulk tank today. Know what fuels you.

    Grease Facts

    Here at Opti-Lube we are committed to finding and providing the best quality grease we can to our customers without them getting a loan to purchase it. We researched, tested, and sampled numerous greases in order to find a superior one that we can all afford. Before the search, we thought, "grease is grease" and "it really doesn’t matter which one you use, just as long as its slick." Holy cow were we wrong! There is a marked difference and you should be using a grease that matches your intended purpose in order to protect your investment. If its not that big of a deal to you what the sorted details of grease are, I would stop reading at the end of this paragraph (before you doze off). At least be assured we stayed awake and did the research in order to find what we think is the cats meow of grease! First of all, grease consists of an oil and/or other fluid lubricant that is mixed with a thickener, typically a soap, to form a semi-solid.

    Soaps include calcium, sodium , or lithium, as well as mixtures of these components. Lithium-based greases are the most commonly used; sodium and lithium have a higher melting point than calcium-based greases but are less resistant to the action of water. Opti-Lube’s grease contains calcium sulfinate. Calcium sulfinate greases usually out perform lithium-complex greases (as you’ll see if you keep reading) and provides much better water resistance properties. We were happy to find ULTIMATE Grease which has a very high melting point (550⁰F).

    Opti-Lube grease is NLGI Grade 2. This number corresponds with the the hardness of the grease, common greases are in the range 1 through 3. Greases with a higher number are firmer, tend to stay in place and are a good choice when leakage is a concern. Our Block Grease is approximately a grade 6. It is approximately the consistency of a stick of butter that has been in the fridge. This grease is used primarily in industrial applications such as mining equipment or railroad locomotives.

    The dropping point of grease is the temperature at which it passes from a semi-solid to a liquid state under specific test conditions. The test involves a test tube where a 'drop' of the subject heated grease falls through a hole in the bottom of a test tube at a specific temperature. Our grease options are designed to function and excel from a temperature range of -40⁰F to 550⁰F. Disc brakes, for example, experience intermittent temperature spikes up to 450 degrees, but run much cooler otherwise. This represents a superior window of lubricating protection.

    Load tests determine the lubricating quality of the grease under specific conditions. There are two load tests: Four Ball EP Weld Point test and Timken OK Load D-1264 test. Examples of both of these tests can be viewed on You Tube. High quality greases will have high Load Wear Indexes of greater than 50 (ours 72), a high weld point of higher than 300 (ours 620), and a wear scar of less than 0.5mm (ours .45).

    The Timkin OK load can also be used to measure extreme pressure protection (look for results greater than 25 kg). Opti-Lube grease test results are 55 kg. Grease ‘tackiness’ is something that may be a concern for some users. Tackifiers are synthetic materials that help grease adhere to a surface and resist water washout.

    The Water Washout test characteristics of our grease products involves placing the grease in a modified bearing/housing assembly while impinging the bearing with a jet of water at a specific flow rate and temperature for an hour. The bearing is weighed before and after testing to determine the amount of sample loss. Opti-Lubes grease reflected a .4% loss at 175 degrees which is an phenomenal result percentage.

    Does grease color matter? Not really. Grease manufacturers use colorants simply to help make simple the identification of greases and to make them more appealing, as opposed to just brown or black. Grease does change color over time though, usually getting darker.

    Can I mix different kinds of greases together? While our grease is compatible with most lithium based greases, it is a good idea to look at a ‘grease compatibility chart’ located on the internet if you are currently using a special grease to see if our calcium sulfinate based grease is compatible.

    It is important to remember that greases, like oils, have a careful balance of properties. A product may excel in one category and perform poorly in another. For this reason, it is important to weigh each property’s significance relative to the intended applications to select the best overall fit. With this in mind, we chose Opti-Lube grease to retain a superior balance that is intended to be an exceptional choice for a wide range of transportation related applications.
