Cannot purchase this locally any longer
Size: 5 Quarts
I cannot purchase this viscosity locally any longer. I was very glad to see it offered here. I use this thicker oil in my 2.2 liter Chevrolet engine that has over 200k miles. It works great.

Great oil but...
Size: 5 Quarts
Great oil. My only gripe is that I need 5.5QT's and single quarts are not available in this weight. Even if it was it looks like a single qt would cost about as much as 5qt's.
