Here’s some expert answers to the most common questions about JET Premium Fuel
Why are dirt and deposits being created in my engine?
When a car engine runs, fuel is injected into the combustion chamber, where it mixes with air. This process, called combustion, creates carbon deposits that can stick to your engine’s vital parts. If you think of your engine like your car’s mouth, then this natural carbon build-up is a bit like plaque on your teeth.
How can I stop dirt and deposits from forming in my engine?
JET ULTRA Premium Fuels are specially designed to deep-clean dirty engines and prevent deposits from building up.1
How can I stop dirt and deposits from forming in my engine?
To make energy to drive your car forward, all fuels undergoes a process called combustion in the engine which creates these carbon deposits and dirt. JET ULTRA Premium Fuels are specially designed to deep-clean dirty engines and prevent deposits from building up.1
What is loss of performance?
As these dirty deposits build up, they can have a knock-on effect on your engine’s performance. You might find your acceleration isn’t what it used to be, there’s a loss of overall power or an increase in emissions.
How does JET ULTRA Premium Fuel clean my engine?
The clever technology inside JET ULTRA Premium Fuel detergent attacks and helps remove dirt deposits in your engine. It also coats vital engine parts in a protective film to prevent deposits from collecting in the first place.1
Will JET ULTRA Premium Fuel work in my engine1?
JET ULTRA Premium Unleaded meets the BS EN 228 British Standard, and JET ULTRA Premium Diesel meets the BS EN 590 Standard. These are British Standards for fuel on which vehicles are designed to run. The effects of cleaning depend on factors such as what fuel you used previously, age, type and state of your vehicle, the road conditions, your style of driving and journey time.
What testing have you done?
We’ve worked closely with one of the world’s leading road fuel detergent providers to ensure that the detergent in JET ULTRA Premium Fuel is subject to world-recognised engine testing standards.
Information provided on our JET ULTRA Premium Fuels site is a result of research and testing by the detergent manufacturer (including laboratory, engine and scientific and industry research on such detergent) and further supported by JETs own scientific literature research.
What’s the difference between JET ULTRA Premium Diesel and Regular JET Diesel?
Compared to our Regular Diesel, JET ULTRA Premium Diesel contains more than double the detergent. The result is a more effective clean for better efficiency and performance.1
What’s the difference between JET ULTRA Premium Unleaded and Regular JET Unleaded?
Compared to our Regular JET Unleaded, JET ULTRA Premium Unleaded contains more than double the detergent. The result is a more effective clean for better efficiency and performance. What’s more, it also has a higher RON (min 97) to give more power to engines that can take advantage of it.1 2
What does the higher-octane (RON) in JET ULTRA Premium Unleaded mean?
You might be more familiar with the term “Super Unleaded”, the common name for higher RON fuels.
RON (Research Octane Number), is the standard measure of a fuel’s performance. Essentially, the higher the number, the more compression the fuel can withstand and the better the performance.2
Because Regular JET Unleaded has a minimum RON of 95 and JET ULTRA Premium Unleaded has a minimum RON of 97, you can use JET ULTRA Premium Unleaded where you can use Regular JET Unleaded. Some car manufactures recommend the use of higher-octane fuel.
Does JET ULTRA Premium Unleaded contain ethanol?
Under the UK Government Renewable Transport Fuels Obligation (known as RTFO), fuel producers have a legal requirement to use a certain percentage of renewable fuels. In petrol, this is normally ethanol, which may be derived from a variety of renewable feedstocks. Petrol with a 95 RON (like our Regular JET petrol) contains up to 5% ethanol. JET ULTRA Premium Unleaded, with its minimum 97 RON, is ethanol-free unless filling up in the Yorkshire and Humber Region, Teesside area or Scotland, where it contains 5% ethanol.
Does your JET ULTRA Premium Diesel contain biodiesel?
Under the UK Government Renewable Transport Fuels Obligation (known as RTFO), fuel producers have a legal requirement to use a certain percentage of renewable fuels. Most road diesel in the UK (including JET ULTRA Premium Diesel) contains up to 7% biodiesel.
