* Increased wear: Aviation oils often have different viscosity grades and additive packages optimized for high-altitude, high-temperature, and high-stress conditions. They may not provide adequate protection for the lower operating temperatures and different stresses found in car engines.
* Seal incompatibility: The seals in a car engine are not designed for the specific chemical composition of aviation oil, leading to leaks.
* Catalytic converter damage: Aviation oils may contain additives incompatible with catalytic converters, potentially damaging them.
* Performance issues: The different viscosity can lead to poor engine performance, reduced fuel efficiency, and increased engine noise.
In short, using the wrong oil is a serious risk, and using aviation oil in a car engine is strongly discouraged. Always use the type and grade of oil specified by your car's manufacturer.
