The CAM2 Racing Heritage goes back to 1966 and the successful Roger Penske/Sunoco Racing program. The award winning CAM2 chemistry in the 20W-50 formula was developed as a three-way venture between Sunoco, General Motors and Penske racing. Using CAM2 racing motor oils race teams competed and won in Trans Am, Can Am, CART Championship (Indy Cars) and NASCAR. Using CAM2 motor oils Penske Racing won at Indy on three occasions with Rick Mears and Bobby Unser. CAM2 racing motor oil was the first multi-viscosity oil to win at Indy.
