My daughter and I are trying to remember where to add oil to the engine. The car was my father's but my daughter inherited it because she helped work on it. In the close-up picture (IMG_2994), we think it is either to the very right or just left of that. Both of them have caps but we don't want to do it wrong for obvious reasons.

Hopefully this question is so stupid that I get a lot of answers. We are trying to figure out where to put an oil additive in the engine. In IMG_2994 we are thinking it is the capped opening on the right but think it might be the one just to the left of that. Thanks for your help. Chris Locke
