Cartagena de Indias
What the manual says, why Cartagena's heat and traffic jams shorten the interval, and how to tell if your car is due for an oil change.
The short answer is in your car's manual. Each manufacturer sets an interval in kilometers or in months, whichever comes first. Kia's maintenance schedule for the Rio, for example, calls for an oil and filter change every 15,000 km. The Renault Logan and Sandero (X52) have an oil-change light that comes on when 1,500 km or one month are left, and the manual says the change is then due "as soon as possible."
That number in the manual is the reference. What no manual says is that oil lasts "10,000 km" or "5,000 km" because it's synthetic or conventional: the engine manufacturer sets the interval, not the oil maker. If you don't know yours, look up your model in our spec sheets: the specification is there, with its source.
Manuals distinguish normal use from severe use, and severe use shortens the interval. The Logan's own manual explains it: the oil-change range "adapts to your driving style," and it lists frequent driving at low speeds, door-to-door driving, and prolonged idling. In other words, the distance to the next change can drop faster than the kilometers you actually drive.
That describes an ordinary day in Cartagena: a traffic jam on Pedro de Heredia, the A/C on full blast with the engine idling, and short trips where the engine never reaches a stable temperature. Add the ambient heat, which makes the oil work harder. A car that only goes from the gated complex to the office and back lives in severe use even if it logs few kilometers a year.
The practical consequence: if your manual gives one interval for normal use and another for severe use, in Cartagena the severe one applies. And if it gives only one, don't stretch it. In Zona Norte and Bocagrande, with long drives at a steady speed along the Anillo Vial or Avenida Santander, the engine suffers less; downtown and in Manga, with a traffic light on every block, it suffers more.
Oil doesn't only wear out with kilometers: it degrades over time. That's why the manual sets a limit in months on top of the mileage. A car that does 4,000 km a year and has gone two years without a change has expired oil even if the dipstick shows the right level.
Write down the date of the last change, not just the mileage. We send you a WhatsApp reminder when the next one is coming up, so you don't have to rely on memory or on the sticker on the windshield.
Three things you can check without tools: the mileage and the date against the manual's interval; the level on the dipstick, with the engine cold and the car on level ground; and the color and texture of the oil on the dipstick. If it's very dark, thick, or has particles in it, it no longer protects the way it should. If your car has a maintenance light, pay attention to it.
And one rule that is in the Logan's manual: check the level regularly and, in any case, before a long trip. If you have to top up more than half a liter every 1,000 km, the manual says to check with the brand. We explain the signs of degraded oil separately in this guide.
The mobile oil change is done wherever the car is, with the viscosity and the standard your manual calls for, and starts at COP $180,000 with synthetic oil and filter. Monday to Friday, 8:00 a.m. to 6:00 p.m., and Saturdays, 8:00 a.m. to 2:00 p.m.; outside those hours, special service paid in advance. Message us with the make, model, and year and we'll tell you your car's interval and the exact price.
Checking terminals, cabin filter, wiper blades and fluid levels needs no lift and no workshop: it's done wherever you have the car parked, in Cartagena and nearby.
The 15,000 km interval for oil and filter comes from Kia's maintenance schedule for the Rio (SC). The 1,500 km or one-month light, the adjustment of the range to driving style (low speeds, door-to-door, idling), and the guideline to check the level before a long trip come from the Renault X52 Phase 2 manual (Colombia), cited in data/aceites.json. That Cartagena's heat and traffic jams amount to severe use is a reading of those definitions, not a figure: NO temperatures or interval-reduction percentages are published.
