What type of oil should I use on my '94 Buick Skylark? (I live in Wisconsin, the car has 199,000 miles approx)

Question

Thanks mang ;-)

Answer 1

You should use a quality 5w30 oil.

Answer 2

I would use high mileage oil they have been promoting. 5w20 in the winter and 10w30 in the summer..

Answer 3

Valvoline 5W 30 or even 10W 30, if you don't want to worry much about changing oil grades during season changes I reccomend 5W  30.

Brands I prefer the Valvoline or Penzoil.

Whatever you do, do not switch over to a synthetic after that many miles and that old of a car.

Hope this helps.
