I have 2001 Boxster S that I purchased a few month ago. Right before the purchase the previous owner had the car serviced at a local shop that specialize in Porsches. Yesterday, I checked the oil level and noticed it needs to be topped-up, the problem is that I don't know what kind of oil was used during the last service. I only have the following info on the invoice from the shop. Any recommendation on what oil I should use to top-up? By the way, I only put about 2,500 miles since that last oil change.
Thanks,
Fabrice
