Quote:
Doug Yates builds all the Roush engines, and he told us that they use a
special blend from Shell that is made just for their engines. I don't
know of any legitimate NASCAR Team that uses anything but our oil,
Valvoline R&D Racing Blend, Mobil R&D Racing Blend or the Shell R&D Racing
Blend. By the way, Roush is sponsored by Valvoline, so I doubt they
gave any other company the go ahead to use their name in conjunction with
selling a competing brand of oil.
