The Duramax engine is one of the best engines on the market but they are faced with one vital issue, the oil pan. The stock oil pan keeps up to 0.5 quarts of dirty left over oil in the system, even after you change your oil it stays dirty! The "hump" that is in the factory oil pan is the reason for this issue, the DmaxStore High Capacity oil pan holds 1 quart more of fluid and will allow you to completely drain the oil from your truck on each and every oil change. We started designing this from the ground up figuring out the real problems that no other competitors address. The pan is made from cast aluminum and has 13 cooling fins located along the side of the pan to keep the oil temperatures down. The oversized Fumoto Oil Drain valve allows for quicker and cleaner oil changes, this valve is 65% bigger than the standard Fumoto valve that is available for stock and other aftermarket pans. This simple bolt on upgrade will keep you Duramax running efficiently and keep contaminants out of your oil.
