What is a 2012 Buick Lacrosse’s oil type?

I just got my full driver’s license, and my grandfather offered me his 2012 Buick Lacrosse. He says the car never spoke to him and that it’s slow. He recently leased a Ford F-150 pickup (even though he’s 84 and has trouble getting into the cab). He said he’d give me the Lacrosse on one condition—I actually learn how to take care of it. So, first thing’s first—what type of oil does a 2012 Buick Lacrosse take?

With that puppy running on all cylinders, you’ll be the coolest cat in town! A 2012 Buick Lacrosse’s oil type is 5W-30 motor oil. Specifically, Buick recommends Castrol Edge High Mileage 5W-30 Full Synthetic Motor Oil.
Now, to impress Gramps even more, here’s some information that you’ll find useful in taking care of your 2012 Buick Lacrosse.
The 5W-30 motor oil needed for the Lacrosse performs well in temperatures both high and low. Both the 5 and the 30 refer to the thickness of the oil, or its viscosity.
The 5 means the oil’s viscosity remains thin even at frigid temperatures, and the W means winter. The 30 indicates the oil will stay thin and keep flowing at super-hot temperatures.
The great thing about using synthetic oil is that it lasts longer. You only have to change it every 7,500 to 10,000 miles. Synthetic motor oil will also be easier on your engine.
Before reassuring dear old Granddad that your Lacrosse is in tip-top shape, check your oil. Motor oil should be light brown or amber, and it should have a smooth consistency. If your oil is dark brown or black or if you smell burning oil or see smoke coming out of the engine, change the oil!
