Merchant Automotive carries the best oil that is designed for today’s high-performance, low emissions diesel engines. They include superior oxidation resistance and promote a longer seal life. Also, you should check out our high-performance oil additive from RevX! This includes a proven formula that can be blended into many types of lubricating fluids to create the ultimate friction reduction agent. This will basically eliminate high thermal temperatures within treated components. The final result will extend service life.
Once you change your oil, you should also change your filter. You can individually source these components or you can purchase one of our maintenance filter packs which include a Duramax Oil Filter, OEM Replacement Fuel Filter, and an Allison External Spin On Filter.
Before you make the decision to replace your coolant, you should check out one of our Merchant Automotive Coolant Analysis Kits. This kit will provide a safe, secure, and economic way to sample and test your Duramax vehicle’s automotive coolant. Once you analyze with one of our kits, you will be able to know exactly if the coolant needs to be changed. If so, we offer a wide variety of coolant options for your Duramax so that you can be sure to find the best match.
How Often Do You Have To Refill Diesel Exhaust Fluid?
Diesel Exhaust Fluid(DEF) is an operating fluid for SCR or Selective Catalytic Reduction technology. DEF isn’t a fluid or additive, but it is injected into the exhaust system to chemically reduce emissions from these diesel-powered vehicles. The Diesel Exhaust Fluid tank will be around 3-5 gallons depending on the specific application. This means it will require a fill every 5,000- 6,000 miles.
How Often Should I Change The Oil On My Duramax?
Engine oil is absolutely critical to long engine life. Changing the oil every 5000 miles is our recommended interval, but the most accurate way of determining intervals is by doing oil analysis testing. It is also important to use the correct engine oil with the correct rating depending on the specific application. You can count on Merchant Automotive to ensure you get exactly what you need.
How Often Should I Change The Transmission Fluid On My Duramax?
For the 2001-2019 Duramax models with the Allison transmission, it is recommended that you change your external spin on filter every 15,000 miles. The automatic transmission fluid every 50,000 miles along with the internal filter inside the pan. Be sure to check out our Blog posts for specific recommendations for other applications.
For manual transmissions, We recommend that the ZF S6-650 6 speed gets serviced every 50,000 miles.
