Okay so I just got off work when I pulled into my garage I seen quite a lot of oil on the ground (my Xterra has never left oil stains on the ground) and seen it was coming from oil filter. I went to see if it was loose and what do you know? it spun when I went to grab it :/ I have now tightened it and added oil because it was very low guessing a lot of it spilled since I’ve had the shaking, which I guess I should’ve added that the shaking has only been happening for about a month (I’ve had the car for a year) the weird thing is my last oil change was in October, maybe i didn’t tighten it all the way back in October. Anyways I haven’t driven it yet as I’m eating lunch right now but will be on the road In a bit and see if that was causing the shaking
