AVGASiks

AVGASiks refers to a brand of aviation gasoline, commonly known as avgas, produced by thePhillips 66 company. Avgas is a fuel specifically designed for use in spark-ignited internal combustion engines found in many general aviation aircraft. It is distinct from automotive gasoline (mogas) due to its higher octane rating and the presence of additives, such as tetraethyllead (TEL), which prevent engine knocking or detonation under the high compression ratios of aircraft engines.

Phillips 66 is a major supplier of avgas to the aviation industry. Their avgas products typically adhere to stringent industry specifications, such as those set by ASTM International, to ensure safety and performance. The most common grade of avgas is 100LL, which stands for 100 octane low lead. The "low lead" designation indicates that it contains a reduced amount of tetraethyllead compared to older, higher-leaded avgas grades. The lead additive is crucial for achieving the high octane number required by many aircraft engines.

The availability and cost of avgas are significant considerations for general aviation pilots and operators. Phillips 66, along with other avgas producers, plays a role in the supply chain that makes this specialized fuel accessible at airports worldwide. Concerns about the environmental impact of leaded avgas have led to ongoing research and development into unleaded alternatives for the future of aviation fuel.
