First oil change at 1800 miles 2012 LT. Hastings filter, store brand full synthetic 5w30, dexos1 rated. My car already had the atrocity of a recall done on it. At first I removed the plug with the filler cap on. I can see how it would have gone everywhere, but with the filler can removed it flowed nicely. I packed rags around the filter, but not one drop spilled, the oil must drain out after the engine is turned off. 24mm socket used, I also used a wobble drive extension and swivel head ratchet to spin the cap off, it's sort of a pain. Do all filters come with a new o ring? Hastings did. I also notice the dipstick takes some wiggling to get it back in. After this, I'll be going by the oil monitor.
