The 2018 Ram 1500 has different oil requirements based on its engine size. The 3.0-liter 6-cylinder diesel engine needs 10.6 US quarts of 5W-40 oil along with a filter. For the 3.6-liter 6-cylinder engine, 5.9 US quarts of 5W-20 oil are recommended, while the 5.7-liter 8-cylinder engine requires 7 US quarts of the same oil. It is advisable to change the oil and filter every 7,500-10,000 miles or 12 months with synthetic oil, or every 3,000-5,000 miles or 6 months with conventional oil. Switching to synthetic oil offers various benefits over conventional oil, such as improved lubrication for engine parts, longer service intervals, and better performance in extreme weather conditions. Synthetic oil with a thinner viscosity flows more easily in cold temperatures, effectively coating engine components to reduce friction and prevent corrosion.
The 2018 Ram 1500 exclusively uses synthetic oil for optimal performance. Its 3.0L V6 engine requires SAE 5W-40 oil and holds 10 quarts. The 3.6L V6 engine prefers SAE 5W-20 and has a 5.9-quart capacity. The robust 5.7L V8 engine also utilizes SAE 5W-20 oil and can accommodate 7 quarts.
My 2018 RAM 1500 with a 3.7 V6 engine consumes oil, typically using about 1 to 1 1/2 quarts every 6000 miles.
Here is a paraphrased and unique version of the text:
"Switching to a 10W oil and 5W-40 oil is necessary for Dodge vehicles, as using 5W-30 has resulted in bottom bearings failures due to a recall.
Your truck may consume oil based on factors such as the type of oil you use (synthetic or conventional) and whether you take short trips in the city without much highway driving.
