This is either an abused stang engine or a defective engine put in at factory. This should be a lesson to those who don't heed the manufactuer oil weight requirements. Don't give the manufactuer any reason to deny your warranty! including using the wrong oil grade specified in the owners manual! Even if you use 30wt and the engine fails like this, who wants to go to court for a year to fight this..even if you win and prove that 30 wt did not cause the failure. You are still out of a new car that you are making car payments for that is sitting. Remember the cathy covington case? bill in utah said ford checked his oil change receipts too. If you don't like 5w-20, don't buy a car that requires 5w-20.
What Ford says about 5W20!

Most computers require a cable that is pinned so certified dealers can retireve engine information. Some computers are even configured with event loggers so excessive events are logged for future reference. And yes this is all used for warranty purposes.
What was your Mustang speced for back in 1998? Do you still have the owner's manual? Just curious.
GM and the EPA went through the same thing with 5w30s back in 1984:

Sorry, there are parts of the memory only the dealer, and a few others, know how to get to.
Well it sounds like it was something defective from the factory or a misshift. Who buys a Mustang to drive easy...just like how I buy BMW's for the fact I like to drive HARD and know they can handle the abuse. If that 4.6 can't handle seeing redline everyday and/or has issues running anything above a 20wt than I would know where Ford is really taking back on the cuts
A V-8 Mustang driven hard ... imagine that. This reaffirms my idea to only buy V-8 Mustangs new, unless you have a lot of mechanical know how to fix what the previous guy broke. I don't even want one to drive fast, I just get goose bumps when I hear that exhaust note.
I wonder if on cars "built" to use 5w20 if perhaps the difference is in the oil pump design, thus causing thicker oils to have problems?
There are parts that only Ford can get to that the dealer has no access for.
Even with a rev limiter you can over rev on a down shift. I remember a Honda owner being denied warranty because the PCM showed that the engine was reved at 15000 rpm when the engine threw a rod.
This story is somewhat difficult to believe since:
1. Why would the owner admit to using an oil other than what is recommended for warranty purposes?
2. If 1. never happened, Ford would have a hard/impossible time proving what grade was used since an oil grade is not readily established from a used oil analysis...especially between a 20 and 30 weight..nor would they ever bother (assuming there's some oil in the engine). So that throws the 'use the warranty-recommended oil' theroy out the window.

Correct, I said dealer instead of Ford. My bad.
So TallPaul, do you have Torco in the sump, acetone in the fuel tank, Yokohama tires on your wheels and did you soldered shut your power valve even if you have F.I.?quote:

Actually I was responding to the following post, but forgot there was another page or posts in between:
No.
Well, I'm at Jiffy Lube today, in Salem, Massachusetts (they screwed up my air pressure on my tires last week when I took it to them to dump the factory fill with MY filter, I made em fix it).
Lo and behold, three Massachusettts State Police cars were in there getting the oil changed, Crown Vics all, 2 2003s, and a 2004, all over 100,000 and one of the 2003s had 188,000. They were pretty candid about them, and they're running 5W20 in them, with (GASP!) Jiffy Lube white filter cans.. The trooper that was chatty said none of them had new engines, these guys were apparently from the same barracks. When they were gone, the mechanic doing my tires (with MY gauge, 42F/40R), confirmed 5W20 in all three with Jiffy Lube filters all.
I'd say the police packages put in these unmarked Crown Vics PROBABLY have hit redline a TIME OR TWO in their long days of service on the Massachusetts Turnpike, I-95, and I-93 north on up to Vermont. And somehow, they held together against all odds with 5W20 Bulk Jiffy Lube oil and Jiffy Lube filters.
Would the Police Packages be a better, stronger build that in the Mustang in question? These engines looked bigger to me in the engine compartment than the 4.6 L that's usual in a stocker Crown Vic by the way, but they had no identifying stickers or labels on them. In any case, bulk 5W20 with Jiffy Lube filters in cars that undoubtedly see severe service every single day. Oh, they bring the cars in every 5,000 miles, so said my chatty Bear-hat wearing trooper. He said he does 5 grand every month and a week, and he takes his car home with him.
Again, all this in big hot V-8s with 5W20, and Jiffy Lube (Fram?) filters. Kinda blows away my former 20W50 old-guy concerns and assumptions that gave me the willies this morning when I put 5W20 Motorcraft with a Hyundai OEM filter into my dinky little new 1.6 DOHC Accent GT this morning.
I have achieved automotive nirvana in Gloucester, Massachusetts today. I am comfy now with the idea of 5W20 SM dino. Anyone care for a lobster to celebrate?

Heres what I say about 10w30. It did'nt cause a bearing to spin. If you want to use 10w30 use it. I ran a used oil analysis on my truck about a year ago with Pennzoil 10w30 it it came back great. I have almost 20000 miles on mine and I plan to keep running 10w30. To those who want to use 5w-20 I say great, good for you, but stop trying to convince me 10w30 is not any good. Not going to happen. 5w-20 is C.A.F.E. driven end of story !!!
Agreed here, too, but the guy had to have abused it SOMEHOW, didn't he? Got cute with a chip, over revved it, something?
We need a Ford mechanic to elaborate. In any case, I'm not going all gushy over 5W20 vs. 5W30 in my case, it doesn't matter in a Hyundai Accent with a 1.6 liter 4-banger in any case. I'd like the engine to last until the body and other mechanicals rot, which, in the case of my last Hyundai, was around 165 or 170K on the engine, and 250K on the body.
That would be adequate service. That these big honking cop cars with whatever size V-8 Interceptors they're sportin run Jiffy-Lube bulk 5W20 oil and Jiffy Lube filters year-round to this number of miles WAS a revelation to me after reading here how suckie Fram and Jiffy-lube is. Rather remarkable. Don't know whether to attribute it to the quality of the engines, the oil, or the (gasp) Fram filters.
Meanwhile, I'm not trying to convince anyone of anything. After all, what do *I* know, anyway?
