As a camshaft grinder I am committed to finding the best products for not only myself but also my customers who rely on my expertise.  I first started using the products out of the Bradford Refinery back in the early 90’s.  Since that time I have not had to worry about oil related issues.  I highly recommend the Penn Grade 1® products to all of my customers, especially those with a slipper follower or flat tappet cams.  For me it is pretty much a given that Penn Grade 1® High Performance Oils are the only lubricant that I am going to use and recommend in my engines.
