I want to do an oil change myself and am not sure what oil to use (even after searches here). Can I test to see if it has synthetic in it now already?....should I just get synthetic? The car has 75k miles and I don't know if starting synthetic oil now will be bad or not...
Thanks in advance!

p.s. JJ, I didn't see you at the Bowl last week!

5,000 miles and a very cold winter later, I am still impressed with the quality of this product.

If that isn't available, Mobil 1 0w-40 is what MB always puts in the cars.
