When I purchased my 1972 Chevy Nova SS I did some research on what oil would be the best for my classic engine, I learned about Penn Grade 1® High Performance Oils and was told by a number of trusted experts that it is the best oil for my high performance classic engine. When I began using I noticed how it comes out clean. I was also impressed that even in 90+ degree temperatures the oil pressure stayed even and the water temperature never went over 195 degrees. I recommend Penn Grade 1® High Performance Oils to all my fellow car enthusiasts because from day one I have been extremely satisfied with its performance.
