The Buick Enclave Oil Pan is one of the parts of vehicle's oil system, which is used to hold the required amount of oil for engine to function properly. Most often using a wet sump system, the oil pan therefore lies beneath the engine and holds oil as it recollects it and feeds it to the oil pump to provide adequate lubrication and cooling of the functioning mechanical parts of the engine. Some of the former models have incorporated stamped steel oil pans, but with the newer Buick Enclave models, car manufacturers use cast aluminum reservoirs for better sturdiness and better performance. Thus, by providing the necessary amount of oil for any driving situation, the oil pan is one of the significant components that contribute to the engine's proper functioning and durability.
