After returning from my 2,100-mile road trip in our long-term 2009 Suzuki SX4, I checked the tires and the oil. I added 1-2 psi of air to each tire. The oil level registered just under the halfway mark on the dipstick, so I added a smidge of 5W30. As one would expect on this class of car, the owner's manual is lenient on the type of oil you may use, suggesting only that it should be a bottle of 5W30 with the American Petroleum Institute seal.
The dipstick is conveniently located (red arrow), as is the filler cap (yellow arrow). However, the mouth is recessed a few inches, so a funnel would really be helpful. I'd left mine at work, though, so I had to dab up some spillage. 
On an unrelated topic, I've forgotten to mention how good the low-beam headlights are on this car. Some time ago, a friend pointed out how large the headlights' reflector boxes are -- which should translate to a good spread of light on dark roads. Turns out he was right. I did a lot of night driving on my Oregon road trip, and the low beams did a great job of illuminating the road -- I only used the high beams on a couple occasions.

One annoying thing I have noticed on some of those plastic engine covers is that there is no real seal around the oil fill.
If you pull off the black plastic cover, you may find some oil buildup and spillage on the top of the engine. After awhile, it can make a real mess so maybe check that out the next oil change.
Just another reason to leave the cover off.

My low-beams completely suck. That's probably my fault though for being cheap with the replacement bulbs. And I probably placed them in improperly. Either way, I need to purchase better lights.
