Sorry this happened to you Hyundai is having laws suit after law suit for engine issues poor engineering no matter what Oil you used would have saved this issue
This is a good report, this Oil seems to run as good as any just make sure to leave the idling time to a near minimum on your 5.7 and you should be good to go!
Its not so much the MDS because the 6.4 has the same issue, but if your Hemi Idles or sits at a low RPM this seems to be the cause, but I agree I would have this retested. I hope this works out for you
Is this the 3.5 Ecoboost? If so be careful with extended oil changes, I know I will get rude comments but I could care less oil is cheap engines not so much.
You still did not answer the question. You stated "The iron difference cannot be attributed to the oil." And sorry If I came off Rude but why did that drop with the Amsoil same mileage same filter
So Please tell me why the differance- I love People That know everything Please Enlighten me I posted my UOA s if you say the oil has nothing to with it then why did it change I will listen may not agree but sure the hell will not be Rude- go ahead Caller
I never wrote the Pentastar is Direct Injection let me repeat that, I should of done a better job explaining my self-**** my opinion is no better than any ones Just a person trying to get ideas. Also I think both oils are great
