Tips for Maintaining Vintage Cars - as part of the expert series by GeoBeats. A good way to maintain your old car is, keep a maintenance schedule on it. You should be doing your oil changes. And with these ones, like, oil changes, grease jobs. Oil change is important, because there is no oil filter on these cars. There is no air cleaner on these cars. Basically, it is nice to keep them in a heated garage, but not all of us have the luxury of a heated garage. So what I do, I usually jack it up. I put fuel stabilizer in for the winter. And I jack it up, and I take the weight off the wheels. I take the battery out, and I put it on a charger. And I put a car cover on top to keep all the dirt and debris off it. So probably in the next week or 2, this one, I will be putting in storage until next spring.
