There are a few things you can do to help your car stay clean and running like new. The first is to regularly clean the inside and outside of the car with a mild soap and water. This will remove any built-up dirt, dust, and debris that may have accumulated over time. Another great way to keep your car running smoothly is by following the manufacturer’s recommended oil changes. Every 3,000 miles or so, change the oil in your car’s engine with a synthetic or unleaded oil. This will help keep your engine running smoothly and prevent it from seizing up.
