What kind of Motor oil to use for Buick LeSabre?

I have a 1997 Buick LeSabre, i juts bought it, don't know what type of motor oil to use. 5W or 10W, any difference? Also, is Synthetic motor oil any good?What kind of Motor oil to use for Buick LeSabre?
10w40 is what you wantWhat kind of Motor oil to use for Buick LeSabre?
It should say in the owners manual, and on it oil cap, what oil should go into that engine.





5W30 is a thinner oil than 10W30, and is (theoretically) more energy conserving.
Depends on what engine is in your car. If it is the 3.1L/3.4L then GM suggests 5w30, if you have the 3.8L then 10w30 is what it takes. Synthetic oil is always a welcome addition to any engine (except for a new or rebuilt because it doesn't allow proper ';break in';)
