This may be a dumb question, but is there a way to tell if the oil in an engine is synthetic or not? I ask because I don't know what is in my TB right now and I always use synthetic when the mileage starts getting up. I'm around 141,000 miles now and the oil was changed right before I bought it this past summer. I don't know what was used, and I'm not sure what, if anything, I need to do when I change it.
Will just a standard drain, filter change, and fill be ok when I change it? I don't know if a flush needs to be done when going to synthetic.
