Industry-wide regulations mean that gas oil can have FAME levels of up to 7%. There have been reports that FAME can cause problems for machinery and fuel tanks, but these can be avoided with proper storage and regular checks. By taking care of your tanks and filters, you can keep everything running smoothly when using gas oil
What is FAME?
Fatty Acid Methyl Esters, or FAME, are fatty acids that can be used as biodiesel. They come from renewable sources, including recycled cooking oils, animal fats and plant oils, which means they can help reduce CO2 emissions. However, FAME also absorbs and retains water which promotes bacteria and algae growth, that can lead to machinery problems, like contamination, clogged filters and lower performance, if coupled with poor fuel storage and maintenance.
Changing regulations around biodiesels
The Renewable Transport Fuel Obligation (RTFO) is one of the government’s main policies for reducing greenhouse gas emissions from fuel used in vehicles and machinery. It states that 8.5%of fuel used in these applications must come from sustainable and renewable sources, and this percentage will increase to 12.4% by 2032.
To meet these regulations, the make-up of gas oil incorporates a bio element, and British Standard fuel can now have up to 7% FAME content.
Potential risks of FAME
Due to FAME’s ability to attract and hold water, as well as its detergency properties, it can lead to problems if gas oil isn’t stored properly.
Steps you need to take to keep your machinery in good condition
When using gas oil, there are ways to protect your machinery against FAME’s potential issues. Based on advice from the UK and Ireland Fuel Distributors Association (UKIFDA) and our own experience, we recommend that you:
