05 1.6 What is correct oil to use? - stevek
The service book says to use either 5/30 or 10/30. Chevrolet dealer has sold me 10/40 saying thats Ok for this engine.
Coments appreciated if it makes any real difference?
Thank you

My local motor factor's oil supplier says 5w-30 www.commaoil.com/.

There's probably not a lot of difference as long as you make sure it meets the spec in your handbook.
