At every oil change it is recommended to replace the oil drain plug gasket. Why? Because the gasket creates a barrier that withstands the pressure and vibration that could go onto the plug itself, potentially allowing the plug to loosen or fall out. Additionally, the gasket conforms to uneven sealing surfaces that the plug may not, again, posing the threat of a leak. AGS has developed a new gasket assortment for our Accu-Fit® Drain Plug System. Keep these within arms reach and have peace of mind knowing that you wont have a comeback from an oil change!
