The engineering put into each one of the generations of the Chevy Duramax diesel powered (2001-current) is at a top-level. Most of the earlier models are still working plus playing hard. The improvements over time as GENERAL MOTORS addressed the ever-changing and restrictive mandates of the Air flow Resource Board and Environmental Protection Agency continued to be a constant challenge. GM engineering held up with these mandates and the organization continues to produce exceptionally hardworking plus stylish trucks that got great fuel mileage, and their longevity is nearly legendary.
PPE looks closely in the elements that make up these trucks. On the many years PPE has been in business they have got consistently made improvements to the successful platforms of GM, Dodge / Ram , Ford , and now Jeep .
One of the more dramatic product improvements PPE has developed is the flat-bottom oil skillet for the Duramax platform. Some do not realize that the stock GM cookware have a depression that resides beneath the drain plug. This “valley” retains old oil even when the particular plug is removed and you believe you have all the dirty oil purged from your internals. As it turns out, just as much as half a quart remains. This really is true for every year 6. 6L Duramax. Not only is this oil left out, but it is the heaviest, dirtiest essential oil because the sludge contains the grit associated with ferrous metals that don’t depart when you drain.
All of us wanted to know more, so we put it towards the test. We ran an up-to-date L5P until it was time for the oil change. We put the girl on the lift, pulled the connect, and let her purge the particular sooty, black fluid just like we’d done so many times before. But on this occasion we were going to see what we hadn’t before – meaning, that older oil that never really leaves.
