On to one of the most important things...
Changing engine oil.
A good set of homemade wood car ramps, a special 86mm oil filter wrench, oil, and oil filter.
The oil filter wrench fits nicely onto the engine oil cap.
A good 3/8" ratchet, and the oil filter cap comes off.
After draining the oil and installing the new filter, add about 6.5 quarts of oil for a 3.0L N51 engine.
Since it is winter, going with the recommended oil of 5-30W.
My $0.015, it is not so much which synthetic oil you use, it is how often change the oil. Typically, I change oil at about the 3,000 mile mark.
What is interesting, is that this engine does not have a traditional dipstick. There is an electronic dipstick that one scrolls through on the instrument cluster to see the amount of oil in engine. Instructions are in the users manual.
Another basic maintenance project done.
Don't worry, things will start picking up soon.
