Fuel Oil Testing Services

The Experts in Fuel Oil Testing and Analysis

Here at Crown Oil Environmental, we have vast experience in fuel oil testing and analysis. We can test a wide range of oils and fuels including engine, gear, transformer, petrol, diesel, and heating oil. The list is almost endless!

Keeping an eye on the quality of your oil and fuel through regular oil testing has never been so important. An increase in FAME content in fuels coupled with the ever reducing presence of sulphur levels, means the risk of fuel contamination is now higher than ever before.

If you believe you have an issue with your fuels or oils, give our fuel testing experts a call on 0330 123 3399 to talk in more detail about the specific oils or fuels that you would like to be tested. Alternatively, read our Fuel Testing & Analysis FAQs for more insight into what’s involved.

Fuel and oil bug alert!

Not only do fuel users need to be aware of fuel bugs or common bacteria associated with microbial contamination, but they should also be aware of the other types of fuel degradation which can occur in modern oil tanks and fuel storage facilities.

This is why at Crown Oil Environmental, we offer complete and comprehensive oil testing and oil analysis services, measuring a full range of fuel quality aspects from our brand new on-site laboratory at our Oil Centre.

If you’re concerned about fuel contamination, why not swap your diesel or gas oil for HVO fuel? The fossil-free, second-generation biofuel is produced through hydrotreatment of renewable materials which removes all impurities from the fuel, leaving a high-quality sustainable fuel that’s less at risk from contamination. HVO boasts up to a 90% reduction in GHG emissions and an extended storage lifespan of up to 10 years.

Fuel and oil assessments include:



ISO cleanliness (particulate examination)

Microbial contamination level

Sulphur content

FAME content

Water content

Petrol contamination (optional)

All of the above assessments are compiled into a simple and easy to interpret oil analysis report, which is issued with every oil sample we assess.

So regardless of your level of knowledge regarding fuel quality, with our fuel analysis service, you will always be well-informed and supported with any guidance or advice required.

Is fuel analysis important?

Yes, to perform at its optimum, a machine must be well-oiled and regularly maintained. If you allow the oil used to lubricate the intricate and important parts of your machine to go untested, it could cause havoc within your machine’s internal components bringing operations to a sudden halt or damaging it beyond repair.

Lubricating & hydraulic oil analysis

We also offer oil testing and analysis for a wide range of oils used for lubrication. Call us today to speak with an experienced analyst about your requirements. We offer a free quote and we’re available 24/7. Call us for advice on transformer fuel analysis.

This typically involves testing for:

DGA (dissolved gas analysis)

Metal in oil checks

Fibre estimation

PCB testing

Buchholz gas analysis

Furfuraldehyde analysis

We also offer fuel tank testing services to make sure that your oil tank is clean and completely safe for use.

In addition, from time to time we may also offer free site surveys and free fuel sampling to some of our prospective clients.
