When I was in college I worked at a service station and our rules, for changing oil, were:
- Always change the filter with the oil.
- Always coat the oil filter gasket with oil and fill the filter, at least half way, with oil before installing it.
- Then fill the car with oil (being careful not to over fill)
- start the car and let it run for 3 - 5 minutes before shutting it off and check the oil again to ensure there is enough in there.
As far as funny gas station stories go, I had an older woman come in with her 1978 Monte Carlo and told me her husband sent her down to have the winter air taken out of the tires and have the summer air put in. It was everything I could do to not laugh out loud while trying to explain to her that there is no such thing.
