So. Ford just replaced the oil burning Voodoo in my 2017 GT350R. If you have one of the oil burners--it's pretty easy to tell. It burns a shit-load of oil. Mine started at about a quart a thousand miles, and rapidly ramped up to a quart every 300 miles. Finally decided I had run enough miles on the oil burning slug at 6,000 miles, and several tests by Ford. The dealer had the replacement motor within a week or so; clearly, they are not wasting time to get fresh motors out. The oil burning cut off is 500 miles/quart. Does it run any better? Holy shit. What a difference. Much smoother and faster--by a wide margin. On the old motor, the oil pressure never got above 100 PSI. The new motor runs 125-140 under throttle. If your motor is only making 100 pounds or so, or you test a 350 and that's what you see--good chance it's a bad motor. Great car, expensive tires. I'm fine with the naturally fast burn rate, but they like to pick up any loose nails on the road, which makes them unusable on the track. No repair option. On set (two) both front and rear at 6,000 miles @ around $3,000 or so.

If it's mileage you're into, I'd be happy to swap tires and wheels with you. No charge. I got 14k out of my first set with 3 track days on them. Although that last track day was kinda wild and wooly.

Hmm my car oil pressure is not that high.. 140 seem hella high though.

They run a lot of oil PSI. Coming from old school muscle, I was a little freaked out seeing triple digit numbers.

There was at least one motor that failed sure due to oil starvation from oil pump pickup seal coming out. I wonder if that was part of the problem here. That could bleed of pressure I would think

There is a separate thread on oil pressure. If I recall correctly, most people reported similar oil pressures (when hot): 90-100 throttle, 40 idle. Don't think there was any correlation to oil consumption. My experience - as my oil consumption has been increasing, I've also noticed higher oil pressures, not lower. I am also currently in the ~ 300 miles/qt consumption.,

Awesome now we can create another thread if you have under a 100psi oil pressure you have a bad motor this should really put everyone over the edge!

Update on my buyback. Ford sent an offer of a full refund plus taxes and fees minus $3500-ish for mileage which was 7k miles. I accepted it and they paying off the remaining loan and sending a check for the difference to my dealer for me to pick up. The whole process was relatively easy it just took a few weeks with calls emails and sending documents for me to sign and return. All and all it was a much more pleasant experience than I expected. Ford took care of me. I am still Ford fan. Waiting on the GT500 reveal.

I, for one, based on my car, am gonna strongly disagree with that statement.

If your motor is hitting 140 psi with Motorcraft 5W-50 oil, there's a good chance that you have a restriction somewhere in your oil circuit, or your pressure gauge needs calibrating.That is what I would be concerned about, no previous data presented on this forum supports that high pressure condition. You shouldn't be seeing that kind of pressure with cold oil, and certainly not with hot oil.

My car at idle is 140 psi and under wot is around 240 psi. I think my motor might be bad due to low oil pressure.

Are your gauges metric ? I did not think the stock gauge went that high?
