Oil is very important to the performance and longevity of your car’s engine. It lubricates different components, keeping everything cool and running smoothly in this otherwise super hot environment. If you don’t have enough oil, or if the oil is dirty from overuse, your engine can overheat. Or, parts can wear down prematurely. To prevent this, have your oil changed regularly. If it’s been a while since this job was done, be sure to get it done before your trip. This is also a great opportunity for your mechanic to change any filters that are dirty and require replacement.
