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

That's not good. Oil has an operating temp range. It's generally accepted that 180* is minimum operating temp. Much below that, and it's not working the way it's supposed to. Unless we're talking about C*.

Maybe the second statement has something to do with the first. You're using a quart every 1,000-1,500 miles. That's a lot of oil for something used so gently.

That sounds like too much oil to me for that setup, and the oil sounds a bit too thick , that oil temp also sounds high, and are you saying you are cruising at 5000?

Should be about 9.5 to 10 qts depending on pan.

With 6000 miles on the clock you should be down to 1 qt per 1000 miles on the ford racing windsors , hopefully less.

Have you done a static and leak-down compression on your cylinders ?

Interesting. I also have the 351 Windsor Ford Racing 385 hp engine. Bulletproof. I change the oil once a year. I use Mobil1 0-40. Burns no oil - no need to add anything between changes. Around 60 lbs pressure.

But 7 quarts fills it. Do these engines come with different pans?

Must...mine takes 12 quarts....Ford (Roush) Dealer just serviced it and used a new(?) Ford synthetic XO 5W50 and a FL-1HP filter...the Mechanic said to monitor the temps and consumption but that he didn"t see any reason to think that anything was wrong...we shall see...runs great...thanks Pan and others...
