How much oil does a 1990 Dodge D150 take?
The amount of engine oil a 1990 Dodge D150 requires depends on the engine installed in the truck. In practice, the most common configurations from that era call for roughly 5 quarts with a filter for the 318 V8 and about 6 quarts with a filter for the 360 V8. Always verify with the owner's manual or the dipstick, as exact capacities can vary by engine and changes in oil pan or filter size.
Engine options and typical oil capacities
These figures reflect common configurations from the era. They assume you replace the oil filter during the change; without a filter, the amount is slightly lower.
- 318 V8 (5.2 L): about 5 quarts with a new filter.
- 360 V8 (5.9 L): about 6 quarts with a new filter.
- 4.0 L inline-6: commonly about 5–6 quarts with a new filter, depending on the specific engine and pan configuration.
If you do not see your exact engine listed, check the service manual or a trusted automotive reference for your engine’s precise capacity and any variations tied to the oil pan or filter size.
How to confirm the capacity on your vehicle
To be certain, follow these steps and use the dipstick as the final check for the correct fill level:
- Identify the exact engine code on the engine block or under the hood (e.g., 318, 360, 4.0L).
- Consult the factory service manual or a reliable database for that engine’s official oil capacity with filter.
- Drain the old oil, replace the filter, and add oil gradually until the dipstick shows the full mark after a brief idle and recheck.
- Let the oil settle, recheck level, and top off if needed to reach the correct level.
Using the correct capacity helps protect the engine from over- or under-lubrication and ensures proper oil pressure and cooling.
Summary
For a 1990 Dodge D150, oil capacity is engine-dependent. The most common configurations list roughly 5 quarts for the 318 V8 and about 6 quarts for the 360 V8, with inline-6 variants typically falling in the 5–6 quart range. Always verify with the owner’s manual or a credible service reference and confirm with the dipstick after filling.
