Engine oil does three jobs at once: it lubricates moving parts, it carries heat away from the hottest corners of the engine, and it holds the soot and metal particles that wear produces. Over time it thins, gets dirty, and loses the additives that protect against corrosion. An oil change is the single cheapest way to add years to an engine, and skipping it is one of the most expensive mistakes you can make.
How often? Follow your owner's manual. Most manufacturers give two limits, a distance and a time, and the rule is "whichever comes first". Short trips, towing, dusty roads, and very hot or very cold climates all shorten the interval. If your vehicle has an oil-life monitor, trust it, and have it reset after each change.
Which oil? The manual specifies a viscosity grade (something like 5W-30) and a quality standard. Any brand that meets both is fine. Mineral, semi-synthetic, and full synthetic differ mainly in how long they last and how they behave in extreme temperatures; synthetic usually allows the longer intervals. If you have to top up, use the same grade.
While the vehicle is up on a lift or on stands, these are worth doing or checking in the same visit:
- Oil filter: replace it every time. Old oil trapped in a dirty filter contaminates the fresh fill.
- Drain plug washer: a fresh crush washer prevents the slow leak that leaves spots on the driveway.
- Engine air filter: hold it up to the light. If you can't see through it, replace it.
- Cabin air filter: cheap, quick, and the reason your vents smell the way they do.
- Other fluids: top up coolant, brake fluid, power steering, and washer fluid, and note anything that was unusually low.
- Tire rotation and pressure: rotating at every oil change is the easiest way to remember it.
- Quick look underneath: brake pads, belts, hoses, and any fresh leak are all visible while the vehicle is up.
Whatever gets done, log it in Maintano with the odometer, the oil grade and quantity, and the filter part number. Next time, you'll know exactly what went in and when, whichever shop or driveway it happens in.
