I work with a guy that has a drag car. He uses Brad Penn motor oil and swears by it. Has anyone ever used it or has an openion on it ??

i have used it in my boats and like it,i also like valvoline vr1.

A pro engine builder friend of mine first recommended Brad Penn to me and since then I have used it in drag cars, pulling trucks and boats all with good results. Only less than positive thing I have noticed about it and other guys here on OSO have stated is a decrease in oil pressure during longer runs after about 10hrs on fresh oil. I have been just adding about 1/2 qt. Lucas oil stabilizer and oil pressure returns to normal.
