Scott,

Since you have the turbo it requires 6.1 qts of oil. If the engine prev had "regular oil" or dyno oil and you are changing to synthetic I would recommend draining the oil cooler as well. In fact, I drain my oil cooler each and every time. No since contaminating 6 qts of new oil with 1 of old, now is there.

So what to do. I will assume that you can do a simple oil change. Remember to use a new oil drain plug gasket (aluminum only, copper takes more torque to seal and will eventually strip the threads). Aluminum is designed for 26 ftlbs of torque. Warm the car, drain the oil, remove the old filter, drain the oil cooler and reconnect the lines, replace the filter with a new one, replace the drain plug (new gasket), replace oil.

Draining the oil cooler is easy and sometimes a bit messy. Please refer to Volvospeed Bay 13 (link at bottom) for info. It is best done with a pair of split ring pliers to open the connector just a bit.

Best of luck. Any questions - email.
