But its really, really easy.
1. raise car safely - i drive up shallow ramps with rear tires
2. do it warm so oil drains, but not hot enough to scald you
3. drain oil oil by removing drain plug - 8mm allen mostly centered in aluminum sump (center, rear)
4. remove oil filter, nearby, hanging down upside down, with your favorite filter wrench. I use a strap wrench
5. Filter is replacement element in re-usable plastic cartridge. Don't crack it
6. replace 3 and 4. plug about 25 lb-ft ( or good and snug, but not real tight) filter very hand tight
7. refill. Oil is a subject of religious debate. Use a Porsche approved oil unless you know better. Lots are.
8. Since you don't have a dipstick, try to fill exactly. measure. I think it takes 8.75 qts, but check you manual. Put in less. then get car level and measure. proper fill, IMO is one hash mark below the upper line. Note upper line is not top of readout. When the car is up on the ramps uit is not level and wont read exactly right
This car is very easy to change oil on. Much easier than my other cars.
