Panavia, I have a 351 Ford Racing Winsor...385hp....that is serviced at the local Ford (Roush) dealership and if I understand the reciept...they use 12 quarts of 20-50 Castrol ($7.78) and a Ford FL-1-HP ($18.67)..the car has been serviced there since new (2008) and now has about 6K miles on it...The car will never see a track and is not driven in anger .. the oil temps will approach 110 for short periods(minutes) of low speed high rpm (5000+) use....until I scare myself...the oil pressure is always around 40-50 and I don't see any leaks under the hood or on the garage floor. Since the oil is only changed every 3000 miles cost is not really a concern..but I don't want to spend money for something I don't need.. ps.. It will use a quart or even 2 between changes...bart
