The Fiver is definitely one of those vehicles that is in a no-mans-land between vintage and modern. Now that it is a daily driver, I treat it like a modern car. That would normally mean that I don’t tackle even routine maintenance like an oil change. Time wise, and financially, you cannot beat a $25 oil change on a car that needs 5 quarts of oil. However, as a vintage vehicle, I immediately bought some filters when I got the car. The change of both oil and air filter was very simple, and was needed on both fronts. Some small critter had found the airbox to be a nice home and had stocked up on small seeds. I may do something to help the car breathe a litlle better going forward, but for now a stock filter is back in place.
