What kind of oil does a 1991 Dodge Ram 50 take?
The Ram 50 from 1991 generally uses conventional engine oil with a viscosity of 5W-30 or 10W-30, and you’ll typically need about 4.5 to 5 quarts with a filter for an oil change.
The 1991 Ram 50 was offered with two small-displacement engines sourced from Mitsubishi, and while exact capacity can vary by engine, the basic oil grade guidance remains similar. Always verify the precise spec for your truck in the owner’s manual or on the oil fill cap.
Oil viscosity guidelines for the Ram 50
To help you pick the right viscosity for your engine and climate, here’s a quick guide based on common configurations and operating temperatures for this model year.
- 5W-30 is recommended for cold climates or winter use, where temperatures regularly drop below freezing.
- 10W-30 is typical for general use in temperate to warm climates, offering solid protection for the engine in most driving conditions.
- In very hot climates or for high-mileage engines, 10W-40 may be used if a mechanic recommends it for better oil film strength, though 10W-30 is usually the standard starting point.
Bottom line: use API-rated conventional oil in the specified viscosities; synthetic oils are optional but not required.
Engine options and oil capacity
The Ram 50 for 1991 commonly offered two engines, and oil capacity varies slightly by engine. The following ranges cover typical configurations, including a replacement filter during an oil change.
- 2.0 L engine: Approximately 4.5–4.8 quarts of oil with filter.
- 2.6 L engine: Approximately 4.8–5.0 quarts of oil with filter.
To confirm the exact capacity for your vehicle, reference the owner’s manual or check the engine code stamped on the block.
Practical maintenance tips
Beyond selecting the right oil, follow these maintenance best practices to keep the old Ram 50 running smoothly.
- Replace the oil filter at every oil change to maximize filtration.
- Regularly check oil level and look for leaks, especially as the truck ages.
- Follow a reasonable oil-change interval for conventional oil, commonly around 3,000–5,000 miles depending on driving conditions.
If you notice unusual symptoms such as consumption spikes, smoke, or low oil pressure, consult a trusted mechanic for a deeper inspection.
Summary
In short, a 1991 Dodge Ram 50 typically takes conventional motor oil with a viscosity of 5W-30 or 10W-30, depending on climate, and about 4.5–5 quarts with a filter. The exact capacity can vary slightly between the 2.0 L and 2.6 L engines, so refer to the owner’s manual for the precise specification. Synthetic oils are optional; always ensure the oil meets the appropriate API specification for your engine.
