Why is fuel testing important

If you keep and maintain your own oil supply in storage tanks. Over periods of time, contaminants have the potential to enter these areas and mix with your fuel supplies.

No matter how many precautions you take. It can be difficult to prevent or even limit the effect this can have.

So, it is very important that you perform regular checks to make sure your fuels, are stored in as good a condition as possible.

Issues like diesel bugs and other contamination problems can happen very quickly, so it’s important that you catch the signs of contamination as early as you can.

The sooner you spot the contamination, the easier it will be to clean the fuel. The risk of contamination is also at the highest it has ever been.

The reduction of sulphur levels and FAME content makes it easier for diesel bugs to contaminate and spread through your fuel. The only way to avoid this happening is to monitor your fuel closely.

What happens to fuel when it gets contaminated

If your oil gets contaminated and you then use it in machinery, it can cause serious damage.

While you may be lucky enough to only suffer from a slight setback, contaminated fuel could cripple your business for some time.

Contaminated fuel has the ability to damage machinery and equipment beyond repair, so using it is never a risk worth taking.
