In addition to our independent laboratory testing service, we can visit site to extract the samples for you. We can also offer advice as to fuel storage and when additional protection may be needed.


There are many ways to find out about your fuel quality and to see if you have contamination or not. You can also try our dip slide tests to see if you have bacterial infection, yeast, or similar in your fuel.

The final way is to do nothing; after all the contamination will soon announce itself. That might be by damaging your fuel injectors, meaning you lose efficiency, it might destroy them altogether, in which case you will really know you have a problem. You might find your filters require changing ever few weeks, or you may see traces of sludge, water or other biomass in your filter bowl.

However you choose to approach it, to us doing nothing is not an option; by the time you accidentally find out you have contamination,
its too late and you have a serious issue.

For any fuel storage situation, we recommend your fuel is tested every 3-6 months to ensure you know its quality. We also recommend this service if you have a polishing system installed. Its a cost effective way to ensure you are 'in the know' when it comes to your fuel quality. After all, testing gives you advanced warning - fuel polishing gives you protection.
