Understanding you car’s innermost secrets will ultimately lead to a better relationship with each other. Secrets like, why do you cost me a fortune in fuel? And where does this oil go and why? The good news is, we’re going to help you with the latter of these questions and perhaps save you a pretty penny in maintenance somewhere down the line. Oil is like your car’s cartilage, it keeps everything running smoothly. If there were no oil, all those pieces of spinning metal that your engine is made of would simply smash themselves to pieces. We recommend checking your oil every 5,000km.
