If it is advanced oil-stress management you are looking for, then you might want to check out Shell Argina. This product has been specifically developed to address oil stress. And, anybody in the engine industry knows that finding answers to prevent oil stress will ultimately help increase engine performance. Consequently, once engine performance is improved, it will then result to reduced maintenance cost. All of these are definitely what all engine owners are dying to have their hands on.

As more and more developments are being made in engines in order to advance market and operational performance, engine oils are also equally challenged to keep up with all these innovations. This is because as engines become more powerful, they become more prone to damage. To protect them from damage, they need to use reliable oil. Unfortunately, the kinds of engine oils manufactured in the past are no longer enough to provide this kind of protection to more sophisticated engines. This is where Shell Argina comes in.

To better understand how this lubricant in the line of Shell marine products can help address oil-stress, one must also comprehend how oil stress develops.

There are a variety of reasons that contribute to oil stress which may lead to various consequences due to degrading lubricant performance. There are the market factors which may lead to higher ship repair costs. Then, there are the operational factors which result to more operational complexity. Lastly, there are the engine factors that increase the possibility of engine failure.

The second question that needs to be answered is how oil stress actually occurs? Taking for example medium-speed diesel engine, the oil is exposed to various kinds of stresses which are acid, thermal and asphaltene. Exposure to acid causes base number depletion and ring liner and valve wear. Thermal and asphaltene exposure, on the other hand, causes piston undercrown deposits, ring grove deposits and viscosity increase. In addition, asphaltene may also cause crankcase fouling and fuel pump sticking. It does not have to take a rocket scientist to understand that all of these consequences spell danger engines and, in turn, to the entire business operation.

Taking all of these in consideration, both the causes of oil-stress and the various dangers that oil-stress may cause, Shell was able to come up with a new technology that benefit the industry by providing a product that help manage different kinds of oil stresses.

What does Shell Argina have to offer?

For one, it will be able to help make engines more reliable through ensuring enhanced engine cleanliness. This is because Shell Argina prevents deposits resulting from thermal and asphaltene stresses making it very powerful in keeping the engine clean and protected.

Secondly, it will generate more savings as there is better oil durability and longer serviceability of engine components. With Argina's viscosity control and base number retention, it will be long before you will be required to do either partial or complete oil replacement.

Since being invented in 1901 by a British engineer, Hubert Cecil Booth, vacuum cleaners have become vital in the battle for keeping homes clean. As more of us strive to remove as much dust, dirt and allergens as possible, manufacturers have been improving their models to offer us a better clean.

Yet, despite the advanced technology vacuum cleaners faults can (and do) still develop faults, with a common fault being a loss of suction. Such a fault will see your vacuum leave dust, dirt and various allergens such as pet dander, dust mites and pollen in your home - meaning your home isn't as clean as it may appear.

Thankfully fixing a vacuum cleaner which has lost suction isn't as difficult as it may sound, and there are generally 5 key reasons why the suction has been reduced. These are:

  1. Blocked / Dirty Filter
  2. Blockages in Vacuum Cleaner
  3. Bag / Cylinder Too Full
  4. Gaps in Air Flow
  5. Faulty Motor

Blocked / Dirty Filter:

Most vacuum cleaners have at least one filter, the pre-motor filter. This is designed to stop harmful particles from getting to and damaging the motor in your vacuum cleaner. Due to the job the filters do they can quickly become dirty or worse, blocked - and in such a situation the suction of your appliance will be hindered.

Rectifying a dirty / blocked filter on your appliance is relatively straightforward. Once you've located where the pre-motor filter simply:

  • Remove it from your vacuum cleaner
  • Shake off any excess dirt
  • Wash the filter in warm water (if a washable filter is used, if not replace)
  • Allow the filter to naturally dry for at least 24 hours before placing it back into the vacuum cleaner.

In addition to having the pre-motor filter, many also have a 2nd filter which stops fine dust / pollen particles from leaving the vacuum cleaner and re-circulating into the room. This filter should also be removed and cleaned by following the process above - although if either are considerably dirty it's suggested you purchase a replacement vacuum cleaner filter and fit this to your appliance.

NB: It is important to make sure you do not run your appliance without a filter; doing so can result in further faults developing.

Blocked Hose / Brushroll:

When you consider the dirt and debris your vacuum cleaner comes into contact with, it shouldn't come as a real surprise that blockages can and do occur. The most common area of your vacuum cleaner to suffer from a blockage is the hose - and whilst this will reduce the suction offered, it is also easily rectified.

Simply disconnect the hose and give it a once over for any blockages, if any are spotted these can usually be dislodged using a broom handle or plastic coat-hanger, although be careful not to use too much force as you don't want to puncture the hose. It is also recommended whilst the hose is disconnected you give the area where the hose connects with your vacuum a quick check to make sure there aren't any blockages.

Blockages in your model are not limited to just the hose though, they can also occur around the brushroll, with hair and other fibres usually being the cause of such blockages. Thankfully, nine times out of ten the blockage around the brushroll can be rectified by cutting off the fibres / hair tangled around the part, without the brushroll having to be disconnected.

Bag / Cylinder Too Full:

At first glance the capacity of your bag / cylinder may seem a lot, but it is worth remembering the fuller the bag / cylinder becomes, the less suction offered by your vacuum cleaner - as such, it is important to make sure you're emptying the vacuum regularly.

As a rule of thumb, it's recommended you empty both before they become two-thirds full.

In addition to emptying your vacuum's bag, it is also important to make sure you change it for a new one regularly. This is because the pores in the bag can become clogged by dust particles, which in turn significantly reduces the air permeability and the performance of your appliance.

Gaps in Airflow:

If you've noticed a distinct lack of suction from your model when you're using the hose attachment, there's a good chance you've got a gap in the airflow. Even the smallest hole can reduce the suction power offered.

Unfortunately, over time the hose on your vacuum can suffer from wear and tear which makes such gaps more likely - with pulling the hose too hard when using the vacuum being a common reason for splits and holes occurring. If yours is damaged in either way, you'll need to get a replacement vacuum hose and fit this to your vacuum instead.

Faulty Motor:

If after checking the four areas above the suction in your vacuum cleaner is still poor, there may be a fault with the motor or carbon brushes. In such a situation you will need to replace the motor / carbon brushes.

Replacing the carbon brushes or motor on your vacuum cleaner can be a considerably time consuming and tricky task, which is why it's recommended doing so only if it is really essential.

By taking the time to regularly empty your vacuum cleaner bag / cylinder, clean the filters, and remove blockages you can keep your vacuum cleaner working at peak performance for years to come.
