So while attempting to contradict me you look kind of silly. It is irrelevant TODAY making the need to do so an old wives tale, just like I stated... It's time has come and gone. Have you ever had an engine professional built? I have, attended the dyno runs for break in, wrote a $9000 check (25 years ago) and broke it in on Amsoil and ran it that way for years... Never had a problem. Old wives tale...

This thread reminds me of The Great Oil Debate thread over on one of the Ducati (motorcycle) forums. You want to see blood splatter on the walls? Ask 'what kind of oil should I use in my Ducati.' Chaos will ensue. I run Mobil 1 motorcycle oil in my Ducati because it's cheap, it's available, I've had good luck with M1 in my trucks, and I am just a casual rider. I was told, literally, my motor will seize up very soon.
My 2023 F250 7.3L is supposed to be my last service truck I buy before I retire... what's funny about that is, my previous truck, a 2017 2500HD with the 6.0L gas engine, was supposed to be my last truck, but it's transmission (and other issues) told me otherwise... so I've moved back to Ford. Of all the things discussed in this thread, the only thing I have control over is what kind of oil I put in the motor... defective parts, poor design, low oil pressure, grenading cylinders... none of that is in my control beyond how I use the truck, so like with the Chevrolet, I'm rolling the dice. I crapped out with the 2500, lets hope I have a better roll with the 7.3L Ford.
I made the transition to full syn oils many years ago, mostly because of the extended drain interval and that they flow better at startup... I start and stop my truck 30-40 times a day, so that is a factor. My normal drain is at 7500mi, which has worked well enough all these years, including in 2 V-10's with all their aluminum parts. Some of you are reporting your OCI as 5000mi, even with full syn oils, so I might switch to that.

Actually the early synthetics caused seal shrinkage (sounds like a personal problem doesn't it) which is typically caused by PAO base oils. With the addition of Ester base oils this is no longer an issue. Seal compatibility in a Group 3 base oil (still synthetic) is essentially the same a Group 2 conventional.

Not fighting, you are just wrong... I know that probably hurts your feelings.. hence the ridiculous comment? Synthetics do not cause issues just because you say so

I'm going on my 22nd year as a Ford tech. There is so much misinformation and opinions on here it's comical at this point. We recommend the syn blend for just about all engines in the ford line-up. When someone comes in with their amsoil or their mobil 1 and wants that in their vehicle we put it in. I'll never understand why people feel like their smarter than ford but hey not my problem. The issues with the 7.3L is something to watch, we're seeing more and more issues it seems.

Man I'm not going to pretend to be an oil expert. To me oil is oil, over the years we've seem some very high mile trucks with various engines that run whatever the dealer recommends. Oil change interval obviously play a big part in that, some people are religious about it and some are not. Todays engines are not what they were even 10 year ago. For lack of better term, they're throw away engines when something internal goes wrong. We don't rebuild these things anymore, we swap them out way faster when thats whats needed. If I owned one, I would be most concerned with the warranty, which is why you run what Ford recommends and don't think any more about it.

Probably means the aluminum blocks with the sprayed in plasma cylinder liners. Not enough plasma liner material to bore the cylinders. And any Ford dealer will not rebuild a rebuildable engine which the 7.3 is. Order a new engine or rebuilt pending Fords decision, shows up in a black box drop it in a call the customer for pick up. Send old engine in the black box to Fords rebuilder.
