The use of 90 octane REC fuel in cars has been a topic of discussion, with some people expressing concerns about its safety and potential impact on engine performance. REC-90 fuel, also known as recreational fuel, is an ethanol-free gasoline blend designed for recreational and marine engines that can be damaged by ethanol. While it can be used in some automotive engines, there are mixed opinions on whether it is safe for standard car engines. Some drivers prefer ethanol-free fuels for better gas mileage and performance, while others suggest avoiding it in heavy engines as it may not be effective in the long run. This fuel type is commonly used in small engines and is known to offer benefits such as improved fuel economy and reduced engine wear.

What You'll Learn
Ethanol-free fuel is safe for small engines
Ethanol-free fuel is recommended for small engines that could sit for long periods to avoid the carburetor from gunking up due to aging gasoline in the bowl. Ethanol-containing fuels can cause corrosion and degradation of metal, plastic, and rubber components in small engines, leading to engine clogging, overly high running temperatures, and poor performance. Ethanol also attracts water, which can cause issues with the engine's lubrication and performance.
TruFuel is an example of an ethanol-free fuel brand that is designed for small engines. It is formulated to be free of ethanol and other gummy impurities, reducing the risk of breakdowns and protecting small engines from phase separation, corrosion, and gummed-up fuel lines.
While 90 octane ethanol-free fuel is generally safe for cars, it is important to refer to the owner's manual for the correct fuel to use. Modern cars with knock sensors can adjust to the octane rating of the fuel and prevent potential issues. However, there may be minor performance differences when using a lower octane fuel than recommended.

REC-90 is more expensive than regular gasoline
REC-90 is a 90-octane ethanol-free fuel designed for recreational vehicles and power equipment. While it can be used in cars, there is some debate over whether it is worth the extra cost.
REC-90 is often priced significantly higher than regular 93 octane fuel. For example, one user reported that locally, REC-90 fuel is $3.99, while unleaded 87 is generally $1.99. At twice the price, some drivers may find that the benefits of REC-90 do not outweigh the costs.
However, there are several advantages to using REC-90. Firstly, it has a slightly greater energy density, which can lead to improved mileage. This means that, although it is more expensive to purchase, you may get better fuel efficiency and therefore save money in the long run. Additionally, REC-90 is ethanol-free, which is ideal for equipment with small engines that sit for long periods to avoid carburetor issues caused by aging gasoline.
On the other hand, some drivers have reported that the improved mileage gained from using REC-90 is not significant enough to make it more cost-effective than regular 89 or 93 octane fuel. Furthermore, modern cars are typically designed to operate properly on 10% ethanol fuel, so the benefits of non-ethanol fuel may be negligible for most drivers.
Ultimately, the decision to use REC-90 fuel depends on individual preferences and vehicle requirements. While it may be worth the extra cost for some, others may find that the higher price does not justify the marginal gains in performance and mileage. With the recent increase in fuel prices, it is becoming more challenging for drivers, especially those engaged in motorsports, to justify the costs of their hobby.

Modern cars can adjust to lower octane
Modern cars have come a long way in terms of engine technology and can adjust to lower octane fuel. Engine control systems in modern cars can compensate for low octane by adjusting ignition timing to avoid knocking. This capability effectively tunes engines in real-time, giving drivers more flexibility in the grade of fuel they can use.
Knock sensors in modern cars can detect if the octane is too low and adjust the timing to prevent major engine issues. While using a lower octane fuel may result in reduced performance and fuel mileage, it is unlikely to cause any significant problems in a modern car. The car's computer will sense the lower-grade fuel and make the necessary adjustments to prevent engine knocking and other issues.
For example, a modern car designed to run on 91 octane fuel may have slightly reduced power when using 90 octane fuel, but it will still operate without any major issues. The car's engine control unit (ECU) will adjust the ignition timing to prevent knocking and other potential problems.
It is worth noting that while modern cars can adjust to lower octane fuel, using a higher octane fuel than recommended is usually wasteful. The car's engine is designed to run optimally on the recommended fuel grade, and using a higher octane fuel will not provide any additional benefits in terms of performance or fuel economy.
In summary, modern cars with advanced engine control systems and knock sensors can generally handle lower octane fuel without any significant issues. However, it is always best to refer to the owner's manual and follow the recommended fuel grade to ensure optimal performance and fuel efficiency.

Premium fuel is the highest-octane fuel
REC 90 is a 90-octane, ethanol-free fuel used for recreational vehicles and power equipment. It is safe to use in cars as well, although it is usually priced higher than regular fuel.
In Canada, for example, the standard premium grades are 91-94 AKI (anti-knock index). In China, 98 RON (research octane number) super premium fuel is sold at some state-run gas stations. In India, premium fuel options are rated at 91 RON, with higher-octane variants also available.
Using premium fuel can have benefits for certain vehicles. For instance, the BMW M5 produced significantly more power and torque when using 93-octane premium fuel compared to 91-octane fuel. However, for some vehicles, there may be little to no noticeable difference when using premium fuel. The Honda CR-V, for example, showed a slight improvement in fuel economy at 75 mph when using premium fuel, but this came at a 21% higher cost.
It is important to note that the benefits of premium fuel can depend on various factors such as engine design, driving conditions, and individual vehicle characteristics. While premium fuel may offer higher stability and resistance to knock, it is not always necessary and can be more expensive.

Using the right fuel is essential for car maintenance
Neglecting fuel system maintenance or using the wrong fuel can lead to a host of problems, including decreased fuel economy, poor engine performance, and costly repairs. For example, carbon deposits can accumulate in fuel injectors, intake valves, and combustion chambers, negatively impacting engine performance.
Using the proper fuel for your vehicle is about more than just following the manufacturer's guidelines; it's about taking care of your car, saving money, and reducing harmful emissions to benefit the environment. Your car's engine is designed to run on a specific type of fuel, and using the correct one helps it perform at its best. When you use the right fuel, your car runs smoothly, accelerates efficiently, and delivers the power you expect.
Additionally, some fuels contain detergents and additives that help clean your engine and keep it running efficiently. Using a lower grade of fuel than recommended can cause clogged fuel injectors and other issues, leading to expensive repairs that could have been avoided.
It's also important to note that equipment with small engines that could sit for long periods should use ethanol-free fuel, often called "recreational fuel" or "REC-90," to avoid carburetor issues due to aging gasoline. While REC-90 fuel is intended for power and recreational equipment, it can also be used in cars and may offer slightly improved MPG due to its higher energy density. However, it is generally more expensive than regular fuel, and the price difference may outweigh the potential benefits for some drivers.
