97 taurus wagon engine & oil change

I just purchased this car & I have 2 dumb questions. How do I know if I have a 3.0 liter Duratec or Vulcan engine?? I want to do an oil change, Should I, a) put the car up on 2 ramps or B) jack up whichever side of the car the drain plug is on ( by the way, which side of the pan or car is the drain plug on) Many thanks.

Put the car up on ramps. You never want to get under a car with just a jack holding it up. Jackstands are mandatory if you don't use a ramp. You not only need to get to drain plug, but to oil filter also. So ramps will give you the most room to work with.

what model do you have?
drain plug would be on the driver side (hmmm... like middle part) pretty sure, you're not gonna miss that.
I agree, ramp would b the best tool...
