I took a different route,and purchased a small vacuum pump,just hand one. I then drew a sample of the fluid into a small container,that was part of the pump package $30. I sent the sample off to Blackstone labs,and they send you a pfd file by email. The car had 32,000 miles,and the sample stated that the fluid had the equvalent of 15,000 miles so I did nother. At least now you know where you stand with the vehicle,and your driving habits.
