Let's Be "Transparent"

If Ford has a chronic blown engine failure for 6 out of every 100 FPC engines/cars produced they then have a serious issue and very surprised that they will continue to produce possibly thousands more cars for the 2019MY!
Let's be clear about what I said, and what I didn't say either now, or previously. My count strictly relates to individuals who have directly reported blown engines and who are also among the members of this forum.

If you have read my previous post detailing how this data was gathered, and what constitutes statistical consistency, you would have known that I am NOT saying my survey here is EITHER "statistically significant" OR it relates one for one to the larger pool of owners. It may relate to the larger population or it may not. My numbers did not include folks who had "second hand" knowledge of several additional failures. BUT, on its own, this count is of some interest. And given the number of folks reading this thread, there is a concern.

I would also be surprised if they would "continue to produce possibly thousands of more cars for the 2019 MY." I would also be surprised if Ford did not make some changes for 2019 MY based on lessons learned. I would also be surprised if Ford would discuss any of this publically.

I have been down this road before with performance cars from another manufacturer. One of my best friends and racing buds years ago lost his life from one of these "unfortunate supplier cost cutting exercises."

Have you guys tried Liqui Moly oil?

I just ordered a 18 gt350 on Friday and after reading this thread, it gave me pause on my purchase... But there's no other car I want so I'm going to hope I'm one of the folks that doesn't experience misfortune.

My Audi used to burn oil like crazy. I have an A6 putting down 400 AWHP and it used to burn about 1 quart every 1000-1500 miles. My shop switched me to Liqui moly and now I burn about 1 quart every 5k miles.

I also drive my Audi super hard. It has 90k miles on it and it's still going strong. The difference here is, the Audi doesn't come with a dipstick! The computer tells you when you're low and if you get too low, it just goes into limp mode, limits your red line to 4k and says to add more oil.

I'm not sure if the oil is good for this motor, but the German motors do well with it to reduce oil consumption.

Anyway, thought I'd share.

I have a '16 Audi SQ5 and run the recommended oil in it with no issues. I had the dealer put a dipstick (replaced a plug) in the engine. I prefer that than relying on the computer. It is my daily driver and a fantastic car.

For the Shelby, I strongly recommend that you run the Ford recommended oil or one of the few available equivalents to it. If you were to have a problem, running an oil spec not required by Ford will likely get you a warranty denial. And regarding the oil, check the level frequently! I would suggest checking it at every fuel fill-up, if possible..

I had an oil pump failure on my '14 GT500 and I let a '17 R allocation I spec'd go to my friend.
He's had an engine failure ('17 R) doing road course events. He said it was valvetrain then rod related, but he's not very mechanical, so I'll eventually talk to his dealer and see what they determined.
Car is already back together and he's happy, but it was complete engine replacement.
Also, last on oil, in my experience and talking to others, they will never deny a warranty because of the oil used, the dealer said they've never had that come up, only if oil changes were done.
Use the best oil you're comfortable with, let's not start an oil debate.

1 qt in 3000 miles is "burns that much oil"? That seems to be on the low end of what's being reported
Some cars - like mine - don't burn oil.

No oil consumption at all? That seems to be the exception - I'd be worried!
It doesn't burn oil, oh no. It DRINKS oil like a porn star drinks...! Nevermind. :headbonk:

But no seriously, mine isn't bad either. I just added my 2nd quart last night in a hair over 14,000 miles.

My first 16 GT350 didn't burn oil at all...at least nothing noticeable over 5,500 miles. My two 17s however were a bit thirsty so there is truth to some GT350s burning less oil than others.

There goes my theory that oil usage has to do with how the cars are driven.

We can't draw sweeping generalized conclusions from anecdotal evidence. Even if there were enough experiences to draw an association, it wouldn't prove a causation.

Agreed. That's why I called it a theory.

I still fully believe there's a correlation, just probably isn't statistically absolute. My car only drove on the track for about a 6 month window (14 track days) - no oil burn. But when I started to prep for moving and drove it around town a bit - started burning oil again. I know up in the PNW none of the track junkies seemed to be burning oil. Again, not saying it's a direct correlation, but it does seem like varied RPM under high loads minimizes oil burn.

With all due respect I was only responding to your post #211 whereby you noted that our members have had 19 engine failures which represents a 6.3% failure rate amongst them.

At no time did I suggest that your numbers represent a true or accurate cross section of engine failure rate for the entire volume of FPC engines over the last 4 MY's and would ask that you reread my post #269 whereby I said "If" and was merely suggesting that your percentage of engine failures was certainly not accurate.

Since the 2015MY Ford has produced ~17,500 GT350/GT350R's and to suggest that Ford would have ~1100 engine failures based on a 6.3% failure rate would not be even close to being the case.

Obviously there are some very serious issues with numerous FPC engine failures but certainly not to the magnitude as some members on this forum are suggesting.

:cheers:

Agreed I believe high rpms and low loads around town causes ring flutter and oil burning! High rpms high load rings are pressed nice and tight against cylinder walls and ring grooves and seal perfectly fine.
