Dirt Late Model
I began using Penn Grade 1 SAE 50 Racing Oils when my engine builder, SMS Racing Engines, recommended it to me. I was very impressed from the very first time that I poured THE GREEN OIL into my engine. We had a common problem with our previous oils breaking down in the engine and would have to change the oil after every race. The oil would look like it had a million miles on it. When we went to change the Brad Penn® Penn Grade 1 Racing Oil after the first time we raced with it, the oil still looked brand new!
I was so impressed with the durability of Penn Grade 1 Racing Oils. I can get at least 2 races out of Penn Grade 1 before I even consider changing it! I have recommended Penn Grade 1 Racing Oils to other race car drivers because it is the best oil I have ever used in my 26 years of racing! In addition, I love that it is a 100% made in the USA oil.
