My Experience: Amsoil SS in 2013 Hyundai Santa Fes

Yes and I suppose their product is 100x better? Give me a break. Not much of a ROI.
1. Never claimed M1 was 100x better. But logic would dictate it's not likely worse and quite likely better.
2. M1 outsells Amsoil by a monstrous market share amount.
3. M1 is less expensive, probably due to economies of scale. Given the cost differential it would seem to be smarter to go with M1 even if changing it twice as often.
4. M1 is far easier to locate to purchase for most people.
5. Exxon Mobil has a company value of $420,000,000,000 and P/E ratio of 7. It sells about $400 billion in oil annually, with gross profits around $100 billion annually.
6. Amsoil is a small/medium private company valued at a whole lot less with revenues around 1/2 million dollars annually. Very small potatoes versus XOM. XOMs gross profits are 50x larger than Amsoil total sales annually, or thereabouts with some rough calculations late at night.

To your point, it would seem XOM ROI is, in fact, pretty good afterall.

That's all.

The POWER of moly never cease to amaze me!

Dimer can charge the battery faster because lights run just a little dimmer but still legal. :alien:

You might want to check your figures, I think your Amsoil 1/2 million dollars annually revenues figure is way off.
 
does the bosch have a anti-drain back valve and the other filters not?,or at least working correctly,,was the correct oil level maintained also,,rather unusal to have happen,was the pcv valve changed ,or even reconnected ,or vacume lines?? messed with,,,check using a EA to determine other issues maybe a thought to try
It has a bypass valve. Is that the same?

Nothing else was changed except the oil and the filter.

The oil level wasn’t low. I checked before the oil change.
 
The very BITOG ironic thing, some folks here would have credited the oil. If that BITOG pop brand of oil started with an H.

Honestly, sounds like maybe your turbo is not long for the earth and your OF wasn't doing you any favors. Some oils, especially USED oil can result in the engine sounding relatively louder. M1, yes. Some folks here even claim Amsoil sounds louder. Not one scrap of evidence on any of this.

AND I see some folks are trying to hack on Amsoil. The usual. Interspersing some truths with made up stuff.

IOW the usual thread!
 
Based on how and where I've maintained these vehicles, my logical assumption was that the oil made the biggest difference. Could it have been premium gas, oil filter and oil all combined? Sure.
And it could also be that none of those changes were what stopped the squeal. If the squeal was never specifically diagnosed, there’s no way to say any of your changes made any difference, especially when changing 3 variables at once.

That’s like trying to prove that changing the plug on my toaster, the aerator on my shower head, and flipping the couch cushions over caused my toilet to explode.
 
As I've said before, this was never meant to be a science experiment. Infer what you will from what I've shared. The squeal stopped and the startup and idle RPMs are lower/smoother with these changes so I'm just going to continue as planned until something else changes.

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.
 
My guess is the oil filter and premium gasoline made more difference (if any of the 3 variables made a difference) than the oil. I would try the Bosch filter with Mobil1 next time and see how it sounds....I'd bet it's as quiet (or loud) as the Amsoil.

I also wouldn't be shocked if the indie didn't use Mobil1. Did you bring it in to them or did they stock it? Either way it would be easy for them to do a switcheroo.

Fair enough. This is an oil site after all and I’m realizing how sensitive people are.
 
Well, I am using Mobil 1 now and it is very quiet. When it gets Vocal I will check back with you Zee09! LOL
Ever since Mobil-1 EP arrived in SP / assuming Natural Gas base also, I haven't witnessed an increase in engine noise either.

I no longer walk past the Mobil oil section at auto parts. But I do walk right by Castrol's section - especially at Walmart, since they no longer shelve Castrol Edge EP, which in my opinion, is the only Castrol product that interests me. The Black jug Castrol Edge breaks down much faster (visibly) and looks yucky & thinned, after only 3k service. It turns black quicker than other name brands too. It doesn't even warrant a UOA in my opinion.

No thanks....
If I wanted to spend top-dollars on Amsoil, I'd buy the Signature stuff..... no questions asked and no hesitation.
I ran Amsoil XL for a few OCIs 15 years ago. I really liked it and know Amsoil's a trusted, quality brand.

Well that adds another data point to the scenario. Maybe it wasn’t the oil that solved your squealing noise.

Any mechanic that tells you to just live with a noise until something breaks has failed in my opinion.
Adds another variable. As others have said, depending on the prior filter design, the whole improved experience could be attributable to a superior anti drain back valve on the Bosch Premium filter.
 
We haven't talked about PD pump yet, did anyone mention M1 0W-40? lol

Under Amsoil department, my vote goes for Amsoil SS 10W-30. Lots of moly, low VII and 4.1 Noack. Yummy! ;)
 
1. Never claimed M1 was 100x better. But logic would dictate it's not likely worse and quite likely better.
2. M1 outsells Amsoil by a monstrous market share amount.

That's all.
Small potatoes yet with their miniscule budget the SS product is probably as good or better, not to speak of great tranny and gear lubes.Good company and its totally American. They do alright. Nothing wrong with that. ROI? XOM according to you spends 100x more on R&D yet their engine oil in comparison doesn't show it. 1/2 million in revenue, I don't think they'd bother opening their doors at that rate. Have you seen their operations? Better check those figures.

Who would have thought that turbo squeal was an indicator of oil quality?

Plus the added bonus of your RPM shooting up. Amazing that an oil can do all that.
ask those Ford Mustang guys or Dodge truck guys about those noisy things. Redline Oil, Liquimoly Ceratec, Lubegard Biotech, 5w20 to 0w40 to name a few bringing a solution to a problem. Different ways to skin a cat 😺 but it appears that they bring relief to ailments.
