Shell diesel, especially premium like V-Power, is generally considered better than standard supermarket diesel because it contains advanced additives for engine cleaning, friction reduction, and potentially better performance/economy, though supermarket diesel is perfectly fine and meets basic legal standards for all cars and is a cost-effective choice for everyday driving. While raw fuel quality is similar, branded fuels add detergents that can prevent deposits, but the real-world benefit depends on your car and driving habits; some users notice smoother running or cleaner DPFs with Shell, while others find negligible difference for standard cars.
Is supermarket diesel as good as branded diesel? Yes. Supermarket diesel meets the same basic fuel standards as premium or branded diesel. It's safe for all engines and helps your car run smoothly.
In short, supermarket fuel isn't bad, it meets all the legal standards, and it's perfectly suitable for the vast majority of cars on UK roads. But if you're looking to give your engine a bit of extra TLC, or you drive a performance car, branded fuels with enhanced additives could offer some benefits over time.
Ultra-Low Sulfur Diesel (ULSD): This type of diesel fuel contains 15 ppm or less sulfur, which means lower emissions, cleaner engine performance, and better fuel economy. It also has good cold-flow properties, making it reliable in winter.
Yes standard grade petrol and diesel form bp and shell is superior to supermarket fuel due to addition of proprietary additives. These companies invest millions per year to develop new additives to improve their fuels so you are paying to get a piece of this.
Shell Diesel is a premium grade automotive diesel suitable for use in high speed diesel engines in both automotive and industrial applications.
Shell FuelSave Diesel is designed to help:
It's kind of easy to get fooled into thinking the 'premium' connotation in the more expensive diesels means they will give you more performance, but that isn't really the case. In all cases (BP, Caltex and Shell), I found cetane ratings of regular and premium diesel were all the same.
10ppm diesel contains only 10 parts per million of sulfur, while 50ppm diesel contains 50 parts per million. Therefore, 10ppm diesel is considered ultra-low sulfur diesel, significantly reducing the amount of sulfur emissions compared to its 50ppm counterpart.
Diesel #1 has added detergents.
Over time fuel systems can gum up with sediments and other debris. Diesel #1 contains added detergents to clean injectors and other fuel system components while the engine is running. A clean fuel system not only lasts longer, it improves fuel efficiency and horsepower output.
The fuel you find in supermarkets has the same regulations as premium sellers. And they're held to the same quality and safety standards. So, although it's cheaper, you can be reassured that you aren't purchasing a harmful or unsafe product.
The worst things for a diesel engine involve neglecting maintenance (especially oil/filters), using poor fuel quality, allowing low fuel levels, overloading/lugging the engine, and not letting it warm up/cool down properly, all leading to contamination, excessive wear, turbo damage, and injector/pump failure due to high pressures and sensitive components. Contaminated fuel (water, dirt, high sulfur) is especially damaging, corroding parts and clogging filters in these high-pressure systems.
This is a bad idea because gasoline has the potential to change the combustion qualities of diesel fuel and also to strip essentially lubricating films from diesel parts in areas like the common rail injection system. So we would never recommend doing that.
Reduce Friction
Shell V Power includes molecules, which lower contact friction, that coat moving metal surfaces in the fuel system. This helps the engine run more smoothly and efficiently, which, alongside improved fuel economy, can also translate to better power delivery.
Fuel quality
This enhances performance and improves fuel economy, saving you money in the long run. Ultimately, the choice between Shell and BP fuel often comes down to personal preference and accessibility, as the quality of their fuel is relatively equal.
It is common for B7 fuel to be used in standard engines being suitable for normal engine operation. B10 Diesel fuel also has Cetane but at a 10% level. This fuel level is considered more premium than B7, which also means it is more expensive. B10 Diesel is recommended for high-performance and standard diesel engines.
The TOP TIER™ Diesel Fuel program is currently sponsored and overseen by General Motors, Volkswagen, Daimler Truck, Navistar and Ford – and recommended for both heavy and light-duty vehicles.
Premium diesel burns quicker and more efficiently, giving you both higher performance and a cleaner engine.
Because of our obsession with technological leadership and innovation, Engen Dynamic Diesel with Pro-Drive 10ppm and 50 ppm sulphur content that can be used for both older and newer vehicles.
The simple answer to the question of 'what diesel should I use? ' is 'any' and that the base used for all diesel in Australia is the same blend and will run the same, regardless of what vehicle you drive. The difference is in additive packages that are put into the fuel.
10 Most Reliable Diesel Trucks in North America
Definitely no difference. 10ppm simply implies that it has a lower Sulphur content as compared to 50ppm. If you are an environmentalist, go for 10ppm. The problem with 10ppm is that it is only available at few fuel stations.
Shell FuelSave Diesel is our efficient fuel scientifically designed to ignite and burn more effectively than standard diesel, thereby helping to increase the efficiency of the engine and improve fuel economy.
Advantages of premium diesel
Premium diesel might help your engine to run smoother and cleaner, which can improve performance and economy with regular use. This may be more noticeable with older or higher mileage vehicles than with brand-new cars that haven't yet had time to develop engine build-up.
One characteristic of V-Power diesel is that it is a lot clearer and more odourless than normal diesel, mainly due to the synthetic gas to liquid (GTL) component. The fuel is slightly less dense than regular diesel so, per volume, the unit energy is actually lower than regular diesel.
