However, generally speaking, for a 1995 Dodge Ram 1500, you'll likely want:
* Oil Type: Conventional oil was common then, but you can use high-mileage conventional or synthetic blend if you prefer. Full synthetic is also an option, offering better performance and longevity but at a higher price.
* Oil Weight: This will be specified in your owner's manual, often something like 10W-30, 10W-40, or 5W-30. The weight will depend on your climate and engine. Thicker weights (higher second number) are better for hotter climates and older engines, while thinner weights are better for colder climates and offer better fuel economy.
Do not assume. Check your owner's manual or the under-hood sticker for the exact specifications before buying any oil. Using the wrong type or weight of oil can damage your engine.
