You put engine oil into your car through the oil filler cap, which is located on top of the engine. It's typically a black, twist-off cap labeled with an oil can symbol. Before you start, ensure the car is parked on a level surface and the engine is cool for safety and accuracy. The process involves locating the cap, removing it, and using a funnel to pour in the correct type and amount of oil as specified in your owner's manual. Always check the oil level with the dipstick afterward to avoid overfilling.
Finding the exact spot is straightforward. Pop the hood and secure it with the prop rod. Look for a prominent, screw-on cap on the engine's valve cover (the main metal cover on top). The universal symbol for engine oil is a stylized oil can, often with the word "OIL" or "Engine Oil" printed nearby. If you're unsure, your vehicle's owner's manual has a detailed diagram under the "Engine Compartment" section, which is the most reliable source.
Using a funnel is highly recommended to prevent spills. Engine oil on hot exhaust manifolds can smoke and create a burning smell, while oil on rubber belts can cause them to slip or degrade. After adding oil, always recheck the level with the dipstick. Pull it out, wipe it clean, reinsert it fully, then pull it out again to get an accurate reading. The oil level should be between the two marks or holes on the dipstick, indicating "Min" and "Max." Overfilling can damage engine seals and create excess pressure.
Here is a quick reference for common oil capacities and types to give you an idea, but always confirm with your specific vehicle's manual:
| Vehicle Type | Average Oil Capacity (Quarts) | Common Oil Viscosity (e.g., 5W-20, 5W-30) | Average Cost of Oil Change (Parts & Labor) |
|---|
| Compact Sedan (e.g., Honda Civic) | 3.7 - 4.5 | 0W-20, 5W-20 | $45 - $75 |
| Midsize SUV (e.g., Ford Explorer) | 5.0 - 6.0 | 5W-30 | $65 - $90 |
| Full-Size Truck (e.g., Ford F-150) | 6.0 - 8.0 | 5W-30 | $75 - $110 |
| Hybrid Vehicle (e.g., Toyota RAV4 Hybrid) | 4.2 - 5.0 | 0W-16 | $50 - $80 |
| High-Performance Sports Car | 8.0 - 10.0 | 5W-40, 10W-60 | $100 - $200+ |
