2009 Buick Enclave: What is the oil type and capacity?

The 2009 Buick Enclave takeS5.2 liters (5.5 quarts) of SAE 5W-30 oil. This is a synthetic fluid designed to last longer than non-synthetic varieties, so You can generally go a bit longer between service appointments. Buick recommends changing this fluid every 7,500 miles, but if You drive in dusty conditions or make a lot of long commutes at low speeds, You may need to have Your vehicle serviced more frequently. If You plan on changing it Yourself, a few recommended products include Amsoil, Castrol Edge, Valvoline, Pennzoil Ultra Premium, and Royal Purple. It's a good idea to check the fluid in Your vehicle routinely, even when it's not time to be changed. This will help prevent potential expensive engine repairs that can be resulted from low or old oil. The average cost for this maintenance work is $100 to $140, including labor.
