What You'll Learn

ASDA fuel is sourced from the same refineries as branded fuel
For example, Shell V-Power and Tesco Momentum fuels are said to be identical, except for the absence of additives in the Tesco fuel. Similarly, a user on an online forum noted that their car felt low on power after filling up at Sainsburys, but the issue was resolved when they refuelled with Shell. However, another user on the same forum stated that they observed no difference in their car's performance when using either Shell or Tesco fuel.
ASDA fuel has been reported to be sourced from wherever it is cheapest at the time. This does not necessarily indicate a lack of quality, as all fuel sold in the UK must adhere to minimum quality standards to ensure they do not damage engines. However, some car owners have expressed concerns about ASDA fuel, with one user claiming that it does not last as long in their tank compared to fuel from other brands.
While there is no conclusive evidence that supermarket fuel is inferior, some car manuals recommend the use of higher octane fuel, such as 98-octane, particularly for performance vehicles. Higher octane fuel burns more efficiently and can lead to improved performance or fuel economy. Ultimately, the decision to choose between supermarket and branded fuel depends on various factors, including price, convenience, and the specific recommendations for your vehicle.

ASDA fuel is cheaper than branded fuel
ASDA fuel is often cheaper than branded fuel, and there are several reasons for this. Firstly, ASDA and other supermarkets aggressively cut fuel prices to undercut their rivals and attract customers. Since most people drive to a supermarket for their weekly shopping, offering cheaper fuel provides an extra incentive for customers to choose a particular supermarket brand over another.
Secondly, ASDA fuel comes from the same refineries as branded fuel but doesn't include the same additives. Like own-branded food products, supermarket fuel is a cheap and cheerful alternative to branded products. While some people insist that branded fuel is superior, there is no scientific evidence that supermarket fuel is inferior or harmful to cars. In fact, all fuel sold in the UK must adhere to minimum quality standards to ensure they don't damage engines.
Some people claim that ASDA fuel doesn't last as long in the tank as fuel from branded stations, but this may vary depending on the car. For example, one person reported that their car felt like it misfired after filling up at Sainsbury's, but others have used ASDA fuel without any issues. Ultimately, the decision to use ASDA or branded fuel depends on various factors, including price, convenience, and personal preferences.

ASDA fuel doesn't last as long in the tank
While there is no scientific evidence to suggest that ASDA fuel is inferior to branded fuel, some drivers have expressed concerns about its quality. One of the main issues raised is that ASDA fuel doesn't last as long in the tank as fuel from other retailers, such as BP, Shell, or Sainsbury's. This could be due to a variety of factors, including the additives used, the quality of the refining process, or even instances of site-specific contamination or storage issues.
It's important to note that all fuel sold in the UK must adhere to minimum quality standards, ensuring that it won't damage your engine, regardless of where you buy it. However, some drivers believe that the more expensive fuel offered by major brands includes additives that can improve engine performance or fuel economy. These additives may be absent or included in smaller quantities in ASDA fuel, which could contribute to the perception that it doesn't last as long in the tank.
ASDA, like other supermarkets, engages in aggressive pricing strategies to attract customers. They may achieve these lower prices by ordering fuel from wherever it is cheapest globally, which could impact the consistency and quality of the fuel they offer. While this doesn't necessarily indicate an issue with the fuel, it may contribute to the perception that ASDA fuel is of lower quality.
Ultimately, the decision of where to fill up is a personal one. Some drivers prefer to stick to branded fuel, believing it to be superior. Others opt for the cheaper option, recognizing that it will get them to the same destination, even if it means sacrificing potential engine performance or fuel efficiency. It's worth consulting your car's user manual to see if it recommends using a specific type of fuel, as high-performance vehicles may benefit from premium options.

ASDA fuel doesn't damage your engine
It is a common misconception that ASDA fuel is bad for your car. While some people advise against using 'supermarket fuel', there is no scientific evidence to suggest that it is inferior to branded fuel. In fact, all fuel sold in the UK must adhere to minimum quality standards, ensuring that it does not damage your engine, and supermarkets are no exception.
ASDA fuel comes from the same refineries as branded fuel, and while it may not have as many additives as premium fuel, it still meets the required standards to protect your engine. In addition, ASDA has been known to order fuel from wherever it is cheapest, which does not necessarily mean that it is lower quality.
Some people claim that they get better fuel economy with branded fuel from companies like Esso and Shell. However, this may depend on the vehicle, as some cars may run better on premium fuel due to their performance engines. Nevertheless, for a normal car, the choice of fuel is unlikely to make a significant difference.
While ASDA fuel may not offer the same level of performance or engine protection as premium fuel, it is still a safe and cost-effective option for many drivers. Ultimately, the decision of where to fill up is a matter of personal preference and budget. However, it is important to note that using ASDA fuel will not damage your engine.

ASDA fuel may not be suitable for high-performance cars
While Asda fuel is not inherently bad for your car, it may not be the best option for high-performance vehicles. This is because premium fuels, such as those offered by Shell and BP, often contain additives that can improve engine performance and enhance fuel economy.
All fuel sold in the UK must meet minimum quality standards, ensuring they do not damage your engine, and Asda fuel is no exception. However, premium fuels can offer additional benefits that may be particularly advantageous for high-performance cars. These additives can provide a performance boost and help to keep the engine clean, which may be beneficial for cars with powerful engines.
That being said, the impact of using supermarket fuel, such as Asda fuel, varies from car to car. Some drivers have reported issues with Asda fuel, while others have found it to be perfectly suitable for their vehicles. It is worth noting that factors such as site-specific contamination or storage issues can affect the quality of fuel, regardless of the brand.
Additionally, the octane rating of fuel can impact its performance in high-performance cars. High-performance vehicles often require higher octane fuel, which burns more efficiently and can improve engine performance. While Asda fuel meets the minimum octane requirements, it may not offer the same octane levels as premium fuels.
In conclusion, while Asda fuel is not inherently detrimental to high-performance cars, it may not provide the same level of performance enhancement as premium fuels. For optimal performance, it is recommended to refer to the user manual of your vehicle, as some high-performance cars may specifically advise using higher octane or premium fuels.
