Dorman Engine Oil Drain Plug

Dorman Engine Oil Drain Plugs: Smart Solutions for Every Oil Change

When it comes to something as routine — yet critically important — as an oil change, the drain plug is the last line of defense between your engine oil and the ground. Dorman has spent over a century engineering aftermarket solutions that go beyond simple replacement, and their lineup of engine oil drain plugs reflects that same philosophy: solve the problem better than the original.

The AutoGrade Line: OE Fit Without OE Compromise

At the heart of Dorman's drain plug catalog is the AutoGrade family, marketed under the Oil-Tite! banner. These engine oil drain plugs are designed to match the fit and function of an original equipment plug on specified vehicles, engineered to replace a missing or damaged plug and help ensure a secure seal. AutoGrade plugs are available in a wide range of thread sizes and head dimensions — including popular metric sizes like M12, M14, and M18 — making it straightforward to find an exact match for domestic and import vehicles alike.

For situations where the original threads have been stripped or damaged, Dorman also offers a universal drain plug option. If the threads are stripped on the original drain plug or pan, this universal oil drain plug can be a cost-effective alternative to trying to tap new threads or replacing the entire oil pan on certain vehicles. It is designed to fit pans with factory drain plugs from .500 inch to .750 inch or M12 to M18.

Twist Drain: The Tool-Free Innovation

One of Dorman's most distinctive offerings in this category is the proprietary Twist Drain solution. This oil drain plug is specially designed to simplify changing your oil by replacing your factory plug with a tool-free, clean and easy solution — just push, twist and drain. It features a custom tapered O-ring that ensures a leak-proof seal, and is finished with electrophoresis and anodization for rust resistance. The trademark Twist Drain plug replaces the original equipment oil drain plug and allows for cleaner and easier oil changes.

Magnetic and Plastic Drain Plugs

Dorman rounds out its lineup with specialized variants for specific applications. Magnetic drain plugs — like the M12-1.75 AutoGrade option — help capture metallic debris suspended in engine oil, offering an added layer of engine protection during each drain cycle. For vehicles with factory plastic oil pans, Dorman offers high-temp plastic drain plugs engineered to match. These plugs feature a downward-facing drain hole to keep oil from splashing on chassis components during an oil change, and the internal twist drain valve can be opened or closed with a screwdriver — installable by hand without tools.
