Originally posted by kickster: You cant get 5W40 in Dino oil. I heard the closer the numbers are the less additive the oil has. It requires a lot of additive to make 5W40 Dino oil. I have been using 10W40 Dino oil in my VWs for years. My dad also uses the same oil in his VW.

The thicker is better mentality is alive and well.

I don't think I've seen it (dino 10w-40) on store shelves for at least ten years.
