When you choose the 2008 Dodge Ram 1500 oil type, you should consider the viscosity of your engine oils. So it will be specified by an SAE viscosity classification.
In this case, you can use engine oils with different viscosity and density, like 5W-20 or 5W-30. It has a dual SAE viscosity classification that specifies the viscosity scope from low to high temperatures.
Therefore, you can choose engine oil that is particularly fit to the range of the heat of your engine and fluctuations in your location.
Oil Type Base On Your Dodge Ram 1500 Engine
The following is a guide to choosing the right type of oil for your truck engine at all operating temperatures.
If you have 3.7/4.7L and 5.7L engines, you can use SAE SW-20.
The above engine lubricants increase truck fuel efficiency and minimal-temperature starting.
The specified oil viscosity that suits your truck may be found on the engine oil filling cap.
If your truck has a 5.7L engine with a Multiple Displacement System, you need to apply SAE SW-20 oil.
If you don’t, the MDS may not work properly.
For more information and a deeper understanding, you can check Multi Displacement System in Starting and Operating section.
Also, you may find the recommended engine oil viscosity for your current truck on the engine oil filling lid.
Association des Constructeurs Européens d’Automobiles (ACEA) European Oil Classification
If you live in a European country that uses the classification (ACEA) for service fill oils, you can follow this guideline.
You can use oil for your truck engine (gasoline or diesel) that meets the ACEA classification requirements for:
Energy Conserving Oils
According to the API (American Petroleum Institute), the energy-conserving engine oils are primarily meant to increase the gas mileage of passenger vehicles, pickup trucks, minivans, and light vehicles.
Certain oils have achieved a 1% increase in fuel efficiency. According to a common test method, a benchmark oil containing a greater sulfur percentage seems more impactful.
If your truck has a gas engine, it will be best to use energy-conserving type oil. You may discover the classification of energy conservation on the packaging of your engine oil container.
Engine Oil Identification
Commonly applied engine oil labeling attributes to assist customers in selecting the appropriate engine oil for their Dodge Ram trucks.
You can identify the engine oil by checking the label notations on the plastic container’s front packaging. You can check the top side of engine oil cans to understand the oil specs.
Also, it means API has certified your engine oil. Daimler-Chrysler recommends API Certified engine lubricants. Therefore, you may use Mopar® or comparable lubricating oils.
Can I Use Synthetic Oil?
A variety of lubricating oil is marketed as both synthetic and semi-synthetic.
Always utilize oil that fulfills API and SAE viscosity standards if you decide to select this brand.
Apply the maintenance plan for your particular driving habits.
What About Engine Oil Additives?
The manufacturing company does not recommend the addition of other oil additives to the designated engine oil.
Lubricating oil supplements and additives should never be applied to boost the oil’s effectiveness.
Oil additives must not be applied to lengthen the time between oil changes.
No proven additive is acceptable for engine endurance and does not damage exhaust parts.
Supplements may include undesired elements that compromise engine lifetime through:
- The additive will increase the phosphorous concentration in your engine oil. However, the ILSAC GF-2 and GF-3 regulations limit oil to contain no greater than 0.10 percent phosphorus to limit the truck’s emissions output.
- Adding additives to your engine oil can be toxic due to the increased sulfur, phosphorus, and catalyst content. As a result, the emission performance of your truck up to 80,000 miles is no longer guaranteed.
- Adding supplements can change the viscosity of your engine oil so that it no longer meets the standards of the right viscosity category for you to use.
- If you add several additive products (mix them) from various manufacturers to your engine crankcase, then there can be an incompatibility effect of the mixture. You should avoid mixing various additive products from various brands. The result is that there are reports of low-temperature engine failure cases.
Engine Oil For Diesel
If you have a 2008 Dodge Ram truck with a diesel engine, then you can use low ash diesel engine oil for your vehicle, as follow:
- 5.9L: API classification CJ-4SM (or meet MIL-2104C standard)
- 6.7L: CJ-4 (fulfills the requirements of Cummins CES 20081 Standards)
For a 6.7L engine, you can use Mopar MaxPro SAE 15 W-40 Diesel DPF or other equivalent products.
Low viscosity lubricants should meet API standards or be designated as CCMC G5.
To ensure that your diesel engine oil has been formulated correctly, you can check if the SAE Grade 15W-40 oil meets the material standards of Chrysler MS-10902. Also, it follows the specifications of ACEA 83.84.
You can also use European grade 15W-40 oil that meets ACEA specifications.
SAE 5W-40 oil is also recommended when the minimum temperature drops consistently below -15 degrees Celsius or 50 Fahrenheit.
That’s the guide for the 2008 Dodge Ram 1500 oil type, and I hope this information is useful for you.
