Avgas 100LL is a heavily leaded fuel that is used in aircrafts. While it is possible to run this fuel in a car, it is not advisable as the lead can cause damage to the engine, specifically the spark plugs, valvetrain, and catalytic converters. Additionally, using 100LL fuel in a car that is driven on public roads may be considered tax evasion in some countries.
| Characteristics | Values |
|---|---|
| Legality | Illegal in countries that have road-user tax as a component of their car fuel prices |
| Engine damage | The lead in the fuel will damage spark plugs, valvetrain, catalytic converters, fuel injectors, and O2 sensors |
| Tax evasion | Using 100LL fuel in a car is considered tax evasion |
| Performance | Some older cars may perform better with 100LL fuel |

What You'll Learn
Is Phillips 66 100LL fuel safe for my car?
Phillips 66 100LL is an aviation fuel, and while it can technically be used in cars, it is not advisable to do so.
The main issue with using 100LL in modern cars is the presence of lead in the fuel, which can cause significant damage to the engine and other components over time. The lead can foul spark plugs, ruin O2 sensors, leave deposits on valves, and damage catalytic converters. These issues can be very costly to repair or replace.
Additionally, using 100LL fuel in a car may be illegal in some places due to road-user tax laws. Since 100LL fuel is typically not taxed for road use, using it in a car driven on public roads could be considered tax evasion.
That being said, there are some older car models that originally ran on leaded fuel and may benefit from the use of 100LL. For example, one person reported running their 1973 Mini on 100LL back in the 1980s without any issues. Another person reported that their old Mercury convertible from the early 1990s ran great on 100LL, with smooth acceleration and no pings.
In summary, while Phillips 66 100LL fuel can be used in some older cars without catalytic converters, it is not recommended for modern cars due to the potential for engine damage and legal issues.

Is Phillips 66 100LL fuel legal to use in my car?
It is illegal to use Phillips 66 100LL fuel in your car in any country that includes road-user tax as a component of their car fuel prices. This is because the lead in 100LL fuel will not only damage the catalytic converter but will also ruin the O2 sensors, leave deposits on the valves, and foul the spark plugs. The lead in 100LL fuel will also not play nice with the spark plugs, valvetrain, and catalytic converters.
However, if you have an old car from the leaded fuel days, it needs lead to run properly, and using 100LL fuel can save on lead additives. For example, someone ran their 1973 Mini on 100LL fuel back in the '80s, and the engine was very fast. Additionally, 100LL fuel can be used for race cars, generators, lawnmowers, and aircraft tugs.
It is important to note that while 100LL fuel may be usable in certain situations, it is still not advisable for long-term use in modern cars. The lead content in 100LL fuel can cause issues with spark plugs, fuel injectors, and catalytic converters, which are now commonplace and quite expensive to replace.
In summary, while it may be legal to use Phillips 66 100LL fuel in certain off-road or tax-exempt situations, it is generally not recommended due to the potential damage it can cause to modern car engines and the availability of more suitable fuel options.

How does Phillips 66 100LL fuel compare to other fuels?
Phillips 66 100LL is an aviation fuel. It is a leaded aviation fuel used in piston-engine aircraft. The Federal Aviation Administration (FAA) and aviation community partners launched the EAGLE initiative to eliminate the use of leaded aviation fuels like 100LL by the end of 2030. As a participant in the EAGLE initiative, Phillips 66 is working to develop fuel specifications for unleaded aviation gasoline.
Phillips 66 is also developing UL100, which is intended to be fully compatible with 100LL and its distribution network. UL100 has the same petroleum components as 100LL but replaces the lead package with a manganese-based additive package. Preliminary testing of UL100 has shown equivalent octane and detonation performance compared to 100LL.
Phillips 66 also offers gasoline for automobiles. Their gasoline is Top Tier-rated, meaning it has more detergent than the minimum required by the EPA. Some users have reported that their cars run just as well on Phillips 66 gasoline as on gasoline from other brands like Shell or BP.

What are the benefits of using Phillips 66 100LL fuel?
Phillips 66 100LL is an aviation fuel, also known as avgas, that is designed for use in aircraft with piston engines. While it is not suitable for use in cars, it offers several benefits for aviation.
One of the key advantages of Phillips 66 100LL is its high-quality performance. It is known for its superior fuel quality control, ensuring reliable and efficient operation of aircraft engines. This fuel has been specifically formulated to meet the stringent requirements set by the American Society for Testing and Materials (ASTM), guaranteeing its high standard.
Another benefit of Phillips 66 100LL is its wide availability and accessibility. Phillips 66, as one of the largest refiners of aviation fuel in North America, boasts an extensive supply infrastructure. This includes a network of branded Fixed-Base Operators (FBOs) and multiple fuel exchanges, ensuring a secure and consistent supply of 100LL for aviation businesses.
Additionally, Phillips 66 offers innovative programs and services tailored to the aviation industry. Their Aviation Contract Fuel Program provides easy access to high-quality 100LL avgas through participating dealers. This program simplifies the process of purchasing aviation fuel for various operations, including charter, corporate, and FAR 91, 121, 125, 135, and 137 operators.
Furthermore, Phillips 66 demonstrates a commitment to the future of aviation fuel. As a contributing participant in the EAGLE initiative, the company is actively working towards eliminating leaded aviation fuels in piston-engine aircraft by the end of 2030. They are also engaged in research and development, striving to create unleaded aviation gasoline that meets industry needs while reducing environmental impact.
While Phillips 66 100LL fuel is not suitable for cars, it offers significant advantages for the aviation industry, including high-quality performance, wide availability, specialized programs, and a commitment to innovation and sustainability.

What are the drawbacks of using Phillips 66 100LL fuel?
While Phillips 66 100LL fuel is a popular choice for many aircraft, there are some drawbacks to its use. Here are some of the disadvantages of using this type of fuel:
- Environmental Impact: One of the main drawbacks of Phillips 66 100LL fuel is its environmental impact. The fuel contains lead, which is a toxic substance. Leaded gasoline has been banned in many other industries, and there are ongoing initiatives, such as the FAA's EAGLE program, to eliminate its use in aviation by the end of 2030.
- Health and Safety Concerns: The lead content in 100LL fuel poses health and safety risks for both pilots and ground handlers. While the additives are handled in a controlled environment, the fuel's combustion emits carbon dioxide, which can contribute to air pollution and climate change.
- Cost: Phillips 66 100LL fuel can be more expensive than some alternative options. For example, at certain locations, the price of 100LL fuel is significantly higher than that of UL94 fuel, which may influence the choices of aircraft operators.
- Availability: The availability of 100LL fuel may vary across different regions. Some aircraft operators have mentioned the limited availability of UL pumps, which can impact their fuel choices.
- Engine Compatibility: While 100LL fuel is compatible with many aircraft engines, there is ongoing research and development to ensure that alternative fuels, such as 100M, can meet the engine requirements of the diverse general aviation fleet.
- Spark Plug Cleaning: Preliminary testing of alternative fuels, such as 100M, has indicated that they may lead to reduced spark plug cleaning intervals. However, further research is being conducted to fully explore appropriate cleaning intervals for different types of fuel.
