So I am experiencing some oil loss by looking under the car. its not significant but its leaks droplets here and there probably stick note size. I just had my oil change not even a month ago and temps dropped below freezing recently (so I expect a tech over torqued the cap). I also can see oil pool up in the "valley" on top of the engine block. I made multiple appoints with shops and the earliest I can get in is 3-4 weeks out. I was planning to do it myself but now the weather is dropping to freezing temps and my garage isn't set up to house a car inside to work on, so I'm looking at biting the bullet and just pay a shop to do it while change my spark plugs too. My question is, can I top off the oil until I can get my car into the shop for the next month?
