666Which ASTM (All Silly Test Methods) number is that ?
Rumor has it that Hondas practically brew this recipe by injecting some fuel/ethanol into the oil. Too bad my car doesn't make anyTry the No VII (No.7) oil it will make it even quieter + will clean any deposits around your turbo that may be causing the sound. .
"Turbo squeal" is only a hypothesis of just "one" of the mechanics who looked at it. It is just one of a handful of possibilities you may never find the answer to. I myself doubt it is the turbo as the style of bearing it has would of gave up the ghost a long ago if it was compromised with a "squealing noise". Cam phazer, cam chain tensioner, and the oil filter brand are other places to look. My guess you will never find your answer, unless your turbo dies within a month. Then that is just a guess it was the problem. It's a Hyundai/Kia needs to be on that list too.Correct. It also eliminated the turbo squeal. Not only did it lower initial idle RPMs/roughness, but also the engine just vibrates less at idle after it's warmed up.
Please add ASTM 666 to the bingo card. Also is moly on it? I can't recall.
Good to know. I sure hope you’re right that it’s not the turbo."Turbo squeal" is only a hypothesis of just "one" of the mechanics who looked at it.

Any update on the squeal?Good to know. I sure hope you’re right that it’s not the turbo.
Still no squeal. Car is running greatAny update on the squeal?
And still affecting your idle speed?Still no squeal. Car is running great
Yes. It gets to low idle faster upon startup and just seems to be smoother at steady state idle tooAnd still affecting your idle speed?
That’s even more amazing since the idle reduction is generally controlled by engine temperature. That is just some super oil.Yes. It gets to low idle faster upon startup and just seems to be smoother at steady state idle too

I requested that Astro14 change the title of the thread.You did use "test" in your title. It's important. Please ask the moderators to change the title. Single change, filter and oil, experience. Something like that.
Some folks here are a little jumpy - in reality people line up for real tests. Look at the stuff posted.
Some folks just want to poke and prod, rather than listen.I requested that Astro14 change the title of the thread.
Can you share that statistical analysis with us please?There's a noticeable difference in UOA overal mathematical chart numbers between the two, especially now when SP UOAs for Mobil-1 oils are now abundant, with a most definite downturn in oil additive strengths. Pablo of Amsoil has never mentioned that Amsoil uses inferior base oils - to that of Pennzoil Ultra Platinum or Mobil-1 EP. So I expect Amsoil's base oil and that of HPL, to be at least equal in quality and performance to the Mobil-1 EP.... quite possibly better, as most-all craft oil brands are.
So in my amateur oil sleuth mind, I firmly believe I spent more for Amsoil, because it's an upgrade to Mobil-1 EP. Much like the beer industry I was in for 30 years, the craft beers cost noticeably more than the Buds, Coors and Miller names. But there's a most notable difference in quality and price, when visiting the Micro Breweries across our country.
Amsoil 5w20 has made my old 2002 Ford F-150 run smoother and quieter than it everI own two 2013 Hyundai Santa Fes 2.0T AWD; both bought brand new in 2012. One of them had the dreaded engine failure at 61K miles; Hyundai replaced no problem. Since about 99K miles, my car started squealing only at cold start-up in the morning. I had two dealerships and two indy shops troubleshoot; serpentine belt replaced twice, then eventually the tensioner. Still squeals. One of the indy shops even removed the belt, started the car cold, and it still squealed. They seemed to think it was coming from the turbo. The dealer finally said, "well, if it's not causing any issues, just live with it until something further happens".
Anywho, the squealing continued every morning at cold start-up. This car has almost exclusively seen M1 5w30 synthetic and 6 month, less than 5K mile OCIs; the squeal happened EVEN after fresh oil changes. After doing a ton of research on BITOG, I finally sprung for Amsoil SS 5w30 to give it a shot. Oil was changed yesterday and this morning, zero squeal. In fact, my RPMs were WAY lower at initial start whereas before, they shot up and I had to let them calm down before shifting into gear.
I'll keep you guys posted but from what I can tell, Amsoil SS made a massive difference in how smooth and silent this TGDI runs. Very impressed so far but time will continue to tell. I will likely reduce my OCIs to 3-4 months just given the reputation of this engine and it's higher mileage (112K).
