How can [censored] be the world's leading synthetic oil? How can [censored] meet the specs it does?

You have to take what you read here and run it through some logical analysis.
 
Clevy, I am not a Mobil-1 nor Amsoil fanboy, though I have/do use both. Could you help me understand why you feel Mobil1 is {censored}?
 
This test doesn't prove anything. There are too many variables. There was no control to say that maybe the turbo is defective. Maybe it would have happened anyway, we don't know. Mobil 1™ is the leading synthetic motor oil, and trusted worldwide. If it didn't work, it wouldn't be, period.
 
To those that think that Forced Performance is only stating the obvious, you'd be surprised at the number of people that modify their STI's from 305 factory hp, to 400+ hp and continue to run Energy Conserving oils.

"Test" is probably a strong word, but Forced Performance has a LOT of experience with modified EVO's and STI's. They were actually one of the first ones to spot the turbo oil line screen clogging issues on 2.5T Subaru's.

DUH.


Yup, using an oil in an application it's not intended for may result in undesired results. This should be news to no one.

If you modify your engine (especially to more than DOUBLE the original output) you might need to re-evaluate your oil.

The original article provides good information but has been incorrectly interpreted by some on BITOG.

Could not be any farther from the truth. Real world, high load engine oil testing....unlike bickering over if you should be using Pennzoil yellow bottle or Castrol GTX in a stock Honda Civic.
 
Great read and thanks for posting this.

By the way you are only allowed to bash Amsoil on this site, never but never say anything bad about Mobile One regardless if it is fact or fiction.

And on this site you must also misspell it.
 
We often observe our customers operating our turbochargers beyond their rated power outputs and
max shaft speeds. We like this, and this is why our customers are the baddest MFr’s in the world, they know
how to try hard and they know how to win year after year after year.
The most important thing to remember when you are hanging your [censored] out there over the edge (besides
being SAFE) is that the only thing that keeps your power system from transforming itself into a cool looking pile
of busted up trash is your motor oil. If you want the best protection against lubrication failure for your race
engine then you need to use the proper motor oil.


I think this says it all. They abuse them.

Oil spec'd for a 270 BHP engine used in a 650 BHP one. Specific output is a factor here too. Real world? Nope.

This oil is being used in the wrong application. Surely you agree with that?

They should try these next time:

That is true to some degree. I believe Mobil pays for sponsorship on this site, and Amsoil does not. Would you sponsor a message board that was always bashing and putting down your product?

Mobil has had more bashing than Amsoil on this board in my short tenure here. They only somewhat recently became a sponsor.
 
Look at the Mobil 1 UOA's, especially the M1 EP UOA's. Mobil 1 oil is not that great.
 
I also believe that Mobil 1 earned the title "World's leading synthetic" due to brand recognition. It has nothing to do with their level, or lack, of quality that other brands can equal or surpass.

Here's a test. If someone were to say a word, you would already have a picture in your head of the first product you thought about in that category. Example....

Soft drink ----> "Coke"
Glass Cleaner ----> "Windex"
Trash Bag ----> "Glad"
Sneakers ----> "Nike"

Synthetic Oil ----> "Mobil 1"

and please spare me the argument, "Used by more OEMs than any other motor oil." Any blender could have that privilege if you paid the OEMs to "choose" your oil. It's all about endorsements.

And what sort of information as to how well an oil performs can be gleaned from a UOA?

How much controlled tear-down testing have you done to qualify that statement?

Oh wait, that's right, we are using a tool that is meant to monitor oil life and contamination to gauge oil performance.

Like trying to kill at duck at 2,000 yards with a 12 gauge and spread shot.
 
I think its a valid test, but Im not sure the zddp content of Brad Penn is the difference, its probably the viscosity of the 20w-50 that provides better protection. I dont think they should recommend oils based only on zddp level, I notice they highlight other 10w30's which I dont agree with

In my BMW m50 engine, I ran Syntec 5w-50 because the oil temps were hot, and I was revving the [censored] out of it and using it hard, it just makes sense
The blackstone report looked like it was never stressed

One guy on here last year, was puzzled that he fried his 300zxtt crank bearings while running 0w30 at a road course driving event, while his factory owners manual said to run up to 20w-50 for hot conditions

The trend towards lightweight oils is good...for saving fuel and long ife, but dont expect it to protect in race/severe conditions

They used Mobil One in our school buses and it caused them to break down often. Had they used Amsoil I would be able to spell better.
