Just a Warning .......
#43
I"m going to throw this out for conversation.
Full synthetic oils are so slippery that they are not my choice of break-in oil. I found this out the hard way when I had to replace a jug on the 0-360 Lycoming engine in a my Cherokee. I was running synthetic at the time with good results, being higher oilk pressure and better cooling and a reasonable oil consumption rate per hour.
That cylinder never did break-in, and increased oil consumption to an almost unacceptable level.
That said, I can see why Ford chose this oil for the Boss from the getgo.
It's hard to resist not stepping on the gas peddle from day one. (I did resist reving it to the redline until I had over 1000 miles on it). But the car is meant to be driven and I've seen guys rev limit the Boss from the first day they got it.
So my guess is Ford wanted the best engine oil protection from day one and chose the 5-50 synthetic oil to do so, ..... perhaps at the expense of a slightly poorer break-in and therefore more oil consumption.
Now here's a choker for you,...... I was very tempted to drop the synthetic oil after 1000 miles and go with 10 -30 conventional oil for the next 3000 - 5000 miles to get a better engine break-in, then go back to Ford's full synthetic oil.
I didn't because I wasn't sure of all the implications of doing so, and my oil consumption was not high at all. That led me to conclude that my enging break-in proceedure was relatively successful, so I just dumped the first batch of oil out at 1800 miles to get rid of any metal particles, and re-filled with reccomended oil again, just before I put it away for the winter.
So that's my story,
Your mileage may vary,.........

Hey guys,
I agree with most of the members about checking your oil whether your vehicle is brand new, fairly new, or not so new. It’s a great rule of thumb and it’s also in your Owner Guide. If anyone feels their oil consumption is excessive, please contact your Ford dealer and PM me with your VIN, dealer, mileage, and contact info so I can help.

I wonder if the "oil users" fall into a certain build date range? Mine is #887 and being a quart low after 1800 miles - would certainly fall into this.

Curious about this comment since my 192,000 mile PT uses 1 qt. every 4,000 miles, which seems relatively normal to me.
The valve cover repair that you mention was first presented in the PTCC forums about 2 year ago. At that time there was no TSB, and to our knowledge that hasn't changed. To the best of my knowledge it only affected a very small percentage of 2001 model year PT's.
Heh, guess it doesn't take much to ruin a car's reputation in the days of the internet.

What's normal? I've owned 4 cars in my life ('81, '87,'01','08), and they never required topping off oil. I think its people that have that experience that are a bit surprised when they have to start feeding their engine "extra" oil in between changes.

Well, many PT people were amazed and complained about oil consumption when none of the non 4 banger Mopars were using a drop. Guys with trucks to Chargers were seeing zero consumption and yet many people with PT's were seeing consumption. My buddy keyed me into it, his used a quart every 1000 to 1500 miles.

Back in the day the saying was "if you aren't using a qt in a 1000, you're not lubricating the upper cylinder!"

Heh - I use conventional oil in the PT - changed every 3k since I bought it in '04 with 60k on it. Never had to add any oil between changes.

If it was, it's just the engine breaking in.
If you have 3000+ miles on the car and are using a quart every 1800 miles, it's consuming somewhat more that it should.
BTW, I did my first oil change after 2000 miles.
I don't like the fine metal particles from break-in or particles left in the block churning around in the oil too long.
Cheers,
