When should the oil be changed for Cadillac XT4 based on oil life percentage?
2 Answers
When the remaining oil life drops below approximately 10%, the vehicle's combination meter will display a prompt reminding you to change the oil promptly. Relevant explanations are as follows: 1. Overview: The oil life reminder is calculated by the vehicle's computer based on comprehensive factors including usage time, mileage, engine speed, etc. Generally, full synthetic oil should be changed every 10,000 kilometers or 1 year. Semi-synthetic oil typically requires replacement every 7,500 kilometers or 7-8 months. Conventional mineral oil usually needs changing every 5,000 kilometers or 6 months. 2. Vehicle Maintenance: Vehicle maintenance refers to preventive work involving regular inspection, cleaning, replenishment, lubrication, adjustment, or replacement of certain components, also known as vehicle servicing. Modern vehicle maintenance primarily includes servicing for engine systems, transmission systems, air conditioning systems, cooling systems, fuel systems, power steering systems, etc. The purpose of vehicle maintenance is to maintain clean appearance, normal technical conditions, eliminate potential issues, prevent malfunctions, slow deterioration processes, and extend service life.
I've been driving the Cadillac XT4 for almost two years now. The oil life system is a small percentage display on the dashboard, and it usually prompts an oil change when it drops to around 5%. My car is the 2021 model, and the onboard computer automatically analyzes driving data to calculate the remaining oil life. For example, frequent traffic jams or short-distance driving can cause the oil to degrade faster, so the system will recommend an earlier oil change. I usually take it to the dealership when the percentage drops below 10%, as not changing the oil for too long can affect engine lubrication, potentially leading to increased fuel consumption or louder engine noise. I also make time to check the oil dipstick regularly; if the oil color darkens or becomes thinner, it's a sign to pay attention. The manual recommends trusting the system's prompts and not delaying to avoid damaging components.
