Pennzoil Ultra vs Amsoil XL

Unfortunately without Analyst and pictures of the engine and parts in question the only thing any responsible person could do it speculate.

Yes, and pigs fly. Oh, and my Newfoundland can dance the Rumba while playing the entire symphonic section from The Phantom of the Opera.

I doubt you wanna hear this,but I quite frankly have a hard time dealing with people posting garbage on the internet.There's enough misinformation on this board the way it is anymore.The 5.4 motor has always been a reliable motor.

How many 15K intervals did you do on the 0W-20 ASM?
How many 7.5K intervals on the 5W-20 XLM?

I'm really doubting the oil was at fault, I am trying to help. Most likely some issue like a slow HG leak or other issue.

Well, if you followed appropriate OCIs, that's not the problem. You used Amsoil, so that's not the problem. 5.4 L engines are not known as sludgers, so that's not the problem. Therefore, there must have been something else. Coolant intrusion? Bad PCV? Engine and oil never getting up to temps? Serious fuel management issue leading to sludging?

I agree. At least one UOA to assure you have no coolant leaks or parts wearing unusually. I say every car you own should have a UOA, regardless of oil choice of length of OCI.

As you see from the replies blaming the oil is tough w/o pics and evidence to support it. But I'll toss this out there, I bet shorter OCI's and/or a UOA would have prolonged the life of that engine a little longer. Next time you plan on extended OCI's get a UOA to back it up, don't rely on the blenders claims or sales hype like some people do. I have a friend doing just that with his Hemi Ram, not good IMO.

Were you adding coolant to that engine?
 
No problems with the moter at all the first 100,000 miles,ran like a sewing machine,untill I had the 100k service done,plugs,flush and fill,belt,fuel filter.The mech did break one plug off,5.4 liter's known problem,lucky it was only one.Thats what im asking is there a oiling problem with the 5.4 moters,with all the facts about amsoil just wanted to know why the moter looked so bad on the inside? Not beating up on Amsoil...
 
Please elaborate more on what were your change intervals & viscosity used?

For the first 50k 0-20 weight,changed at 15k severe sched,changed because it was using a qt between changes,last 50k 5w20 xl around 6k.also PI additive avery 4k.Amsoil ATF and Rear end severe gear oil..Amsoil front to back..
 
You are right the dealer told me that they would not cover warranty claim if I used amsoil in my truck so with that said I am going to stay with Pennzoil or Mobil 1.I can buy them for about the same price.

I would talk to your regional service rep if a dealer tried this one on me.

Yeah. That's like saying using Shell Gasoline will void your warranty and you have to use BP Gasoline.

Dealers are there to sell you a product, not help you make the right decision.

I have it on good authority from a friend in Shell lubricants that PU is 100% Group III. I can't provide a link, merely that anecdote.

Another good authority at SOPUS told me that the new PU is PAO. Go figure. But there is no way the new PU NOACK numbers could be so low with 100% group III oil base, IMO.

The SM version was Group 3 no question since Sopus admitted it in the Q&A. The SN version might contain some PAO (I seriously doubt it is mainly PAO).
 
Unfortunately no oil is 100% anything, but Pennzoil got the formulation right with PU IMHO. If I had unlimited funds this is the oil I would use and I would do 12K OCI's.
 
I agree with Capa & Dave. The SM was definitely Group III. Noack volatility is a good indicator of base oil types. If the current PDS for PU is correct, then I would believe it's majority PAO.

SOPUS makes good oil.
