One of your Duramax diesel engine’s dirty little secrets is the stock lower oil pan has a low spot in the sump that traps over 2 ½ cups of old dirty oil that is impossible to drain at service time. Who wants dirty oil left in the oil pan after your oil change? The OEM steel oil pan is also extremely susceptible to rusting.
The Banana Pan is made of 356-T6 aluminum, complete draining, one time fix for your engine. The Banana Pan makes it quieter, allows you to add a heater and optional magnetic “GoldPlug” protection, and it won’t rust out! #dumpthehump #gotruckyourself
