Diesel Fuel... Are You Getting What You Paid For or Buying a Problem?

Diesel engine designs striving to increase engine performance have made great advancements in engine fuel delivery to the combustion chamber. Today’s diesel engine is quieter, smoother, and more powerful. But today’s diesel engine owners are overlooking one important factor. The quality of today’s diesel fuel has not advanced at the same rate as the engine improvements. Diesel fuel begins to deteriorate as soon as it is produced. Within 30 days of refining, all diesel fuel regardless of brand, goes through a natural process called re-polymerization and oxidation. This process forms varnishes and insoluble gums in the fuel by causing the molecules of the fuel to lengthen and bond together. These components now drop to the bottom of the fuel tank and form asphaltene also known as diesel sludge. The fuel begins to turn dark in color, smell bad, and in most cases causes engines to smoke. The engines smoke because some of these clusters in the early stages are small enough in size to pass through the engine filtration and into the combustion chamber. As these clusters increase in size, only part of the molecule gets burned. The rest goes out the exhaust as unburned fuel and smoke. With increases in cluster size they begin to reduce the flow of fuel by clogging filters. The filters only address the symptom and not the cause. It is estimated that eight out of every ten diesel engine failures have been directly related to poor quality and contaminated fuel. The build-up of contaminates in the fuel systems and storage tanks can quickly clog filters, thus resulting in engine shut down, fuel pump wear, and diesel engine damage.

Understand that most fuel has some amount of water in it from either condensation or vents. This threat requires that we realize the added burden placed upon diesel fuel as opposed to gasoline. Gasoline acts as a fuel only. Diesel fuel, on the other hand, also must cool and lubricate injection system parts. These parts are engineered to very close tolerances - up to 0.0002 of an inch - and any contamination means rapid part wear. Water displaces the diesel fuel. When the fuel is displaced wear occur because lubrication is now absent. Water that enters the combustion chamber results in even more serious damage. When it comes in contact with the heat of the combustion chamber (in excess of 2000 degrees F), it immediately turns to steam and often explodes the tip of the injector. Water causes corrosion of tanks, lines, injectors, and greatly reduces combustibility. Other areas of concern include the producing more exhaust emissions and effecting EPA standards.

Bacteria also present a serious problem. Bacteria feed on nitrogen, sulfur, and iron that may be present in the fuel or tank. Then there are algae. There are absolutely no algae in diesel fuel. You may have fungus and microbial contamination but no algae. This is a misnomer for diesel sludge. So if you have a diagnosis of ALGAE and add a biocide, you have done two things, 1) found a mechanic that is wrong and 2) done nothing to fix the problem. Why is there so much bad fuel? The number one reason is due to the increased popularity of diesel power and the accompanying increased demand for more diesel fuel. There was a time when diesel fuel remained in the refinery storage tanks long enough to naturally separate and settle, allowing the clean fuel to be drawn off. Now with increased demand, diesel fuel never remains stationary long enough for settling, and the suspended water and solids are passed on to you, the user. The change in refinery techniques is another problem. In order to get more products per dollar; diesel fuel is now being refined from more marginal portions of the crude oil barrel. This results in a lower-grade product that is inherently thicker and contains more contamination.

Thirdly, current fuel distribution methods also have a negative impact on the condition of the fuel at the time of delivery. In many cases, brokers control fuel sales to major distribution terminals and determine delivery dates. There is no telling how long that fuel has been in the distribution network and how many times it has been transferred. Seldom do these distributors filter the fuel as they transfer it. The solution: Multifunctional diesel additive packages and hardware. For your single vehicle or fleet the improvement of fuel quality by the use of additives and current technology is always a good choice. Many diesel fuel additive packages address the key issues with respect to fuel performance; some improve fuel economy, increase lubricity, improving cold flow, and improve cetane number. And some only address the issue of rust and corrosion, but all should be considered. Most diesel fuel additives contain combustion improvers that release oxygen during the compression stroke. This allows combustion to start sooner, providing for a more complete fuel burn. A more complete burn provides all the power your fuel and engine is capable of producing. As combustion improver and you get a smoother running engine, an increase in horsepower that improves fuel economy and the reduction in black smoke emissions.
 Cetane is a performance rating of a diesel fuel, a higher cetane number or cetane rating indicates greater fuel efficiency. The fuel’s cetane influences, duration of white smoking after start-up, drivability before warm-up, and intensity of diesel knock at idle. Increase the cetane number of a fuel and you have improved performance. In diesel fuel systems, the fuel provides lubrication for the fuel pump and injectors. A fuel with poor lubricity can cause excessive wear and premature failure of these components. Improve lubricity and extend engine life. Diesel fuels have pour points (the lowest temperature at which an oil or other liquid will pour under given conditions) within the range of normal winter temperatures. As a fuel approaches its pour point, paraffin in the fuel form wax crystals that prevent it from flowing. Flow-improver additives modify the wax crystals, lowering the pour point of the fuel and give better cold weather performance. For on-sight storage tanks other issues must be looked at.

On-sight storage tanks always have a small amount of the first gallon of fuel ever put in them, unless it is drained 100% and cleaned. So adding new, fresh fuel always has a bit of the bad added to it every time fuel is purchased. Diluting the bad with good over time is a loosing battle. The fuel will always be bad fuel until the core problem is addressed The order of treatment for fuel related problems should always begin with a determination of whether there is water in the fuel and if the fuel has microbes (fuel bugs) in it. Water Paste and Fuel Test Kits can be used for this stage of maintenance. If microbes are detected, then the use of biocides is needed. Biocides have no effect on and will not eliminate the sludge problem. Biocides kill bacteria, that’s all! The water issue should always be remedied first by the use of fuel water separators on the tank or on the equipment.

Next a multifunctional chemical additive should be added to improve fuel performance and then if needed a problem specific additive to dissolve diesel sludge and or a rust inhibitor to protect steel tanks. For long-term prevention, the use of magnet fuel conditioners is recommended. These devices continually reverse the re-polymerization of the fuel during circulation and reduce the need for ongoing additive use. There is no good time to find out that your engine won't operate or that half its life span is gone prematurely because of contaminated or poor quality diesel fuel. Since no one can predict a breakdown, the only safe method is prevention. Realize now that you do have a problem, and manage it now, or deal with the unexpected catastrophe and reduced equipment life that comes at the absolutely wrong time and is not in the budget! 

Pickup Sales Falling: There's A Good Reason Why

Pickups, for years, have been the best-selling vehicle in the United States. But recently released year-to-date sales are showing that overall, pickup truck sales have fallen this year. Sales for the Nissan Titan have dropped more than 9% this year. In September of 2006, more than 6,000 Titans were sold. This past September, sales barely beat the 5,000 mark. Chevrolet's Colorado and Ford's Ranger are faring far worse. Sales for the Ford Ranger are down more than 20% over this time last year. September sales for this year are down by 43% compared to 2006. Chevy's Colorado is down more than 18% in overall sales for the year and even sales for the popular Chevy Silverado are down nearly 2%. Nissan's suffering as well with an 18% drop YTD (year-to-date) with the Frontier, and GMC's Sierra is barely holding on to market share with a 1.6% drop in sales over last year. This can be alarming for some people looking for a car, van, or SUV but most buyers agree that the risk far outweighs the reward.

On the flip side, Dodge's Ram is holding steady—actually up one percent over last year and has sold more than 500 more Rams in September '07 than it sold in September 2006. Toyota's also doing well. Even though sales for the Tacoma were down by almost 3,000 vehicles this past September compared to the September prior, year-to-date sales of the pickup are up by 1.2%. Tacoma's sleek older brother the Tundra is doing exceptionally well, up more than 50% over last year.

So why are the sales of certain companies on the decline while others are holding steady or shooting toward the stars? It could have to do with the minor improvements made in safety features to last year's pickups. Since safety has shown in multiple studies to be a "very important consideration" among consumers of automotive vehicles-- and to those who bought pickup trucks specifically-- companies that have upgraded safety equipment seem to be garnering favor.

Isuzu is one of these companies. Isuzu's i-290 offers advanced safety features like Dual-Stage Airbags, an airbag suppression system, a Four-Wheel Anti-Lock Braking System, Tire Pressure Monitoring System, Daytime Running Lights, and Child Seat Lower- and Top-Tether Anchors for those with young children. The bigger i-370 includes similar features as the i-290, but also offers Head-Curtain Side-Impact Airbags, a Day/Night Auto-Dimming Rearview Mirror, Electronic Traction Control, Shift-On-The-Fly 4-Wheel Drive, and Automatic Locking Rear Differential. The i-370 sports all of these features in both the Extended and Crew Cab models.

The 2006 Toyota Tacoma also performed well in crash tests, proving its worth. With a "G" rating (the highest of four possible ratings) in six out of seven categories, according to IIHS (Insurance Institute for Highway Safety), it certainly deserves to be mentioned along with the Isuzu i-290 and i-370.

In addition to active and passive safety features, comprehensive roadside assistance programs are now being considered as a valuable part of a vehicle purchase. Isuzu offers one of the best roadside assistance packages available. It offers free roadside assistance for up to 7 years or 75,000 miles.

Military Grade Toughness, Yet Comfortably Civilian

The Hummer off-road legacy is soaring high in both military and civilian use. After 14 years of making Hummer with a record of 12,000 units made, the production of the famous H1 Hummer finally ceased. The assembly plant manufacturing the H1 was converted into a facility that concentrates on the production of military grade High Mobility Multipurpose Wheeled Vehicles or HUMVEEs. Despite the closure, the company proudly announced that not a single employee lost a job.

Hummer is a large 4x4 off-road vehicle considered in some countries like New Zealand and Australia as a truck because its high fuel consumption do not pass the standard set for normal Sport Utility Vehicles (SUVs). Originally built by AM General (the merger of American Motors and Jeep), General Motors continued to use the Hummer brand after it acquired the rights over the brand name from the former in 1999. Hummer shares that distinguished 7-slot front grill with Jeep, also a leading 4x4 off-road automobile maker. AM General continued to produce the Hummer in South Bend, Indiana. Hummer is now officially a division of General Motors.

The Hummer was featured in ESPN in 1990 for a documented off-road trek from London to Beijing, passing by the rough terrain of the former Soviet Union. Its reputation as a reliable 4-wheel drive vehicle reached its peak after its noted performance in Operation Desert Storm in 1991.

Today the H2 and H3 2008 models, the civilian versions of the Hummer, are widely sought after in the large- and mid-size SUV market. Arnold Schwarzenegger became so delighted by a parade of HUMVEEs during the filming of the Kindergarten Cop in 1990 that he became one of those who called on AM General to produce a civilian version of the Hummer.

The 2008 H2 is a Sport Utility Vehicle (SUV) and its variant, the H2 SUT is a Sport Utility Truck with a six-foot pick-up extension that extends the flexibility of your H2. Powered by a 6.2-liter V8 engine, the H2 can deliver 393 horsepower and 415 lb-ft of torque to its 6-speed Hydra Matic 6L80 automatic transmission.

It has a 9.7-inch high ground clearance and traction is managed by an automatic Traction Control System capable of applying brakes selectively to individual wheels. The Panic Break Assist is a unique feature that makes this vehicle an outstanding off-road companion.

The new 2008 H3, meanwhile, is a mid-sized SUV with variants such as the ordinary H3, H3 Alpha and the H3x. H3 is basically a smaller Hummer, more nimble and fuel efficient, easier to drive than the original H1. H3 Alpha is mounted with a more powerful Vortec 5.3-Liter V8 cast Aluminum block and cylinder head engine, capable of delivering 300 horsepower at 5,200 rpm. The ordinary H3 has a Vortec 3700 3.7-Liter cast Aluminum engine.

The H3x is a city version of the H3, a mix of generous chrome accent in the body and the wheels, a roof rack crossbar and more comfortable accessories. The H3 is available in 5-speed manual and 4-speed Hydra Matic 4L60 Transmission. The H3 Alpha is only available in 4-speed automatic transmission.

Hummer committed to embrace bio-fuel technology in developing its future models. Schwarzenegger has converted his own Hummer to bio-fuel capable engine. Join the Hummer caravan and let everyone know you are traveling tough yet in business class comfort. Show them you own one with your Hummer Keychains. Flawless metal designs are engraved with the “Hummer H2” or “Hummer H3” text. Join Baja 1000 race champ Rod Hall in driving Hummer and celebrating his 40-years in off-road racing.

Getting Paid Off Collecting Jeep Parts

There’s nothing worse than deciding to try a new brand of product and finding that they just aren’t as good as your usual one. It’s worth the try sometimes to quantify just how good a product really is, because after using or having the same thing for a long period of time you can lose the appreciation of the item.

Just like fashion, it’s also amusing to see trends come and go. And then there are the times where the hardcore fan will tell you that they knew the product was cool all that time. I have a brother that is one of those very loyal nothing else will do fans. Particularly when it comes to Jeeps.

It’s not until you see someone who is really into them that you notice just how much paraphernalia can be associated with one vehicle. Strangely enough, it’s not just what the individual collects; it’s all the things that get given to him because people know how much he loves them. Unfortunately for him, his wife just doesn’t see the same appeal in all the things he has collected over the years. You see while jeep stuff might be appealing for a guy it doesn’t really give a house that homely feeling. There is only so many ways of decorating with posters, stickers, cups, key chains and t-shirts.

Several years of accumulating jeep stuff has resulted in many boxes being stored in the garage and not so much being displayed. There would be no question as to the final resting place of all this stuff once the garage got packed.

Funny then how a change of outlook can make the worthless suddenly seem valuable. You see my brothers’ wife was bidding on some items online when she happened to come across some items that looked remarkably like the ones stored in her garage. On closer inspection she found that the items were indeed the same and to her utter surprise the bidding was strong and the items turned out to be quite valuable.

Needless to say that when she had finished looking on the internet she went straight to the garage and started sorting out the items in the boxes. With a new appreciation of the value of the object she had decided that perhaps she had overreacted in her need to have the items packed away.

When I go to my brothers’ house now there are displays where the older jeep objects are kept. Although they have not been given prime positioning in major living and entertaining rooms they take pride of place in the office.

While I wouldn’t claim that there has been a conversion to the jeep faithful, it is not uncommon now to see my sister-in-law actually making use of the jeep mugs for her tea. Whether she does it because she really values the pieces or whether it’s out of respect for my brother no one really cares.

Nerf Bars And Truck Side Steps - One Leg Up On the Others With 5 Main Features

Side tubes, nerf bars, step bars, running boards. Whatever you call 'em, they look great and work even better. The need for side steps has grown as trucks and SUVs have gotten taller. You'll discover a number of features and benefits with a set of side steps, including:

- A stable extra boost up into your cab

- Safe stepping in any weather

- A variety of shapes and styles

- Heavy-duty materials for overall strength

- A multitude of finish choices for a smooth and tough appearance

- Sturdy mounting in a matter of minutes

Nerf bars, side tubes and running boards are sure to give a boost to tired legs and your vehicle’s looks, too. That’s right, nerf bars and running boards sure look cool and they do give a welcome step to hard worked legs. But they also help protect your vehicle’s body from those inconsiderate folks that swing their doors open without a thought. They’ll think twice next time after slamming into a solid nerf bar.

A guide to the extra boost provided by side steps

Whether you've got a low-rolling midsize SUV or a monster truck, you could probably use a solid step beneath your door for an extra boost when you need it. Nerf bars and running boards can be a welcome sight after a tiring day at the job site or an energy-sapping stint at the office. Think of your other riders, too. The sturdy stepping place provided by a set of nerf bars or running boards is a great measure of safety and peace of mind for your younger or older passengers.

Side steps are built to handle frequent use, too. They bolt-on to your vehicle in a pre-existing mounting position on the frame. This makes for sturdy installation that can handle whatever your passengers' feet dish out.

Side steps also boast incredible weight capacity. The typical set of nerf bars can hold 300lbs. or more at a time, supported by the steel construction and heavy-duty frame mount brackets. Most running boards boast an aluminum support frame beneath the stepping surface, giving these side steps a weight capacity of up to 500lbs.

The basics of safe stepping in any weather with side steps

Wet weather can make for unstable footing everywhere. That's why nerf bars and running boards feature treaded pads that help you get a grip on the step before climbing into your vehicle. These all-weather pads feature a grooved design that channels water away from the stepping surface.

Beyond providing a non-slip surface for stepping, nerf bars and running boards keep the mess from getting to your vehicle's carpet. The treaded pad is an excellent place to wipe your feet, while the tube or board itself becomes an ingenious tool for knocking off the mud.

The all-weather step pads stay in place with heavy-duty adhesive that's sure to hold for the life of your tubes. Plus, they're installed to recesses in the board or tube, meaning the strength of your step isn't compromised with a cutout.

The basics of side step materials

Nerf bars typically use thick-wall steel tubing to get their strength and durability. Either cold-rolled carbon steel or stainless steel are the metals of choice, with the carbon steel only used on powder coat models.

Running boards feature molded polymer top surfaces. It's a high-strength plastic, supported underneath by an integrated aluminum frame for added rigidity. That's how the wider, thinner running board can support more weight than standard tubes.

Ground Clearance

Side step thickness varies greatly, especially among nerf bars. For standard tubes and steps, non-lowered trucks and SUVs will have no trouble. Lowered trucks and SUVs may have clearance issues with any tubes or steps. And, only full-size trucks can tackle jumbo-sized 4" nerf bars. Just another thing to keep in mind when deciding to customize your ultimate driving machine.....:)
