Your "operators manuel" should explain which type of oil to use. I have a 96 Buick, LaSabre, that uses 10/30 wt.
check your manuel
what size of car battery do i need for a 2003 buick lesabre
body lift
DextronDextron
10w30 says it right on the oil cap.
R 134A (hint it is also in your manual)
Your hands, your hands
this new type of gas called butt gas
The 2005 Buick LaCrosse has a 4-speed automatic.
If your car has 100.000 miles on the engine,it's best to use 50 weight racing oil. My 90 lesabre has 293000 miles I use 10w30. Thicker oil will not flow to the bearings as quick and is not recommended by GM.
The 2005 Buick LaCrosse runs on regular unleaded.
