SMART-O® oil drain plug / sump plug is designed to protect engines and the oil pan. In a different way than magnetic oil drain plugs / magnetic sump plugs, SMART-O® reduces wear on the oil pan thread and reduces risk for catastrophic oil loss which could damage the engine. The current market demand for quick lube and express oil changes ("5 minute oil changes") increases the likelihood for untorqued or negligently installed oil drain / sump plugs.

Wear and Tear - Oil Pan Damage

Busy mechanics or auto service technicians are prone to human error. In the rush of servicing many vehicles, it is easy to install a similar looking, but not perfectly fitting plug, thereby damaging the threads of an oil pan.

Stripped oil pan threads also occur due to normal wear and tear, which can lead to a less accurate plug fit.

Some mechanics feel it's safer to over torque a plug if they see the oil pan is worn, instead of applying manufacturer's specified torque values. However, overtorqued plugs or misaligned plugs will damage oil pans over time as they wear the thread off.

In the worst cases, this will result in using an oil pan repair kit or a complete replacement of the pan.

Prevention is the best solution. SMART-O plug utilizes a special head marking system which makes it easier and faster to identify the right plug, and no over-torquing is necessary to safely seal the oil pan.

Oil Leaks

The oil pan can lose oil due to a variety of factors including faulty or worn out seals and gaskets, or worn oil pans. The result can be oil drips on your driveway, garage floor and ultimately, into the environment. In some juristictions, this can lead to fines for environmental clean up.

Engine Damage from Sudden Oil Loss

If oil drain plugs / sump plugs suddenly loosen due to improper fit or even negligent installation, then a sudden loss of plug and engine oil might occur. This can result in the engine losing all lubrication and burning up in the process. For vehicle owners this means replacing an engine, which will involve claim cases with the auto service center, work shop or quick lube. For lube or auto service operators, this means insurance claims and loss of profit.

SMART-O Magnetic Oil Drain Plugs / Sump Plugs collect metal shavings to prevent them flowing back into the engine. This will help prevent wear and tear on the engine over time. (This product is currently in the prototype stage - scheduled for future release).
