Filter Swap and Replace Drain Plug Crush Ring
One of the greatest advantages of a Nissan oil filter is the anti-drain back valve that prevents oil from draining from the top of the engine back to the oil pan while your vehicle is running. This feature prevents a “dry” or un-lubricated start up of your engine and saves wear on critical engine components. We also install a new copper crush ring on your drain bolt which allows proper tightening of the drain bolt. We frequently see tow in vehicles that were serviced elsewhere that do not have a crush ring and are leaking engine oil or in some instances, have no oil left in the engine. A small detail that can make a big difference.
