5w30 for summer 10w30 for winter

 

Anyone know some info with mobile 1's regular vs. extended performance?

 

What is the difference between Mobil 1® Extended Performance and Mobil 1?
Mobil 1 Extended Performance formulas are designed specifically for today's longer service intervals and are guaranteed to protect for up to 15,000 miles or one year.

Mobil 1 Extended Performance has a unique formulation with a boosted level of protection and performance. Mobil 1 Extended Performance, with the Advanced SuperSyn System, contains 50 percent more SuperSyn than Mobil 1. (Updated March 2006)

your question answered on mobil's website.

AMSOIL SSO 0W30 killed mobil one extended performance on th 4 ball wear test, leaving a wear scar that was only like .4mm, whereas the mobil one was like 1.2 or something like that. AMSOIL is the best stuff you can run in your car, period. It has better quality detergents, base stocks, and additives, as well as the manufacturing process being suprior. All of their oils are filtered down to a micron level far beyond the requirements that the automotive industry sets. It's more than twice as expensive as mobil one, but you get what you pay for.

 

This is what I run.

 

Can't go wrong with factory spec Mobil 1.

And now to contradict myself . I put in 0w-30 Amsoil Yesterday, and I've only gone about 50km since then, but with no complaints yet.

I have full faith in both the Mobil 1 and the Amsoil.

 

So where is the test report for the Amsoil vs Mobil 1?

I tend to not consider Amsoil because it's never sold by any of the large parts stores (NAPA, Carquest, etc). Every time I see an Amsoil advertisement it's either a small plastic sign stuck in the ground at the corner of some intersection, or it's a magnetic sign on the side of some old beat down contractor's pickup truck. They don't have a very good marketing campaign, and when that's true, it normally means the product is snake oil. Even going on Amsoil's webpage and looking for local dealers, I get a list of individuals and not businesses.

I'm interested in reading the test report.

 

If you do a search on google there are plenty of tests for amsoil out there.

 

Eneos, but it is very pricey. Amsoil, RP, and M1 EP are good as well.

 

Here is where I've found some info on oil when deciding for my first oil change (most of which include amsoil).

I wouldn't use one as a reference but many. I ended up going with Amsoil 0w-30, but I don't think you can go wrong with Mobil 1 + a few others as well.

 

I've already done the search, I've already read the test reports published by Amsoil. There is no third party test I can find. Many things in this thread are either wrong, or very apples to oranges. For example, four ball test wear was not .4mm vs 1.2mm, it's actually .45mm for Amsoil vs .55mm for Mobil 1, which is incredibly insignificant given the extremity of the test.

"Third party ASTM test report", but it actually isn't because it was paid for and published by Amsoil.

The only other ASTM "test report" I found but it's for gear oil, and it's on an Amsoil sales website whihc makes it not "third party":

Most of the tests in the second link show the results bewteen Amsoil and mobil 1 being so insignificant, I can't see how anyone who read AND UNDERSTOOD the testing, would care one way or the other which product they used.

I'm assuming, and probably wrongly so, that there actually is a third party test, not paid for by Amsoil, not published on Amsoil's website, not published by one of the Amsoil dealers, which is available as an actual test report, and availble complete, rather than one that picks and chooses the best results in order to maximize the marketing value of a particular product. When I see this one, I'll begin believing. Until then I'll keep believing Amsoil is just MLM.

 

Have you had a look at any of the links I've posted^^?

In any case I'm not trying to convince you that Amsoil is any better than you believe it is... Especially coz I wont be footing your repair bills regardless of the oil you want to use .

As far as I'm concerned picking between Mobil 1 and Amsoil is like buying a 7 or 7.1 mega pixel camera.

 

@ evostang: Well, AMSOIL pays money to have these tests done by INDEPENDANT LABS to make sure that these tests can be repeated anytime, anywhere in the world. Mobil one doesn't spend any money on proving their products, they just have the market niche of a well known name and can provide an oil that is good at a cheap price. Mobil one costs half what AMSOIL SSO OW30 does, so look at it however you want. If you really think that AMSOIL is lying even after spending money on tests to prove their claims, then look up the magazine "fast fours and rotaries," which is an australian magazine that has absolutely no affiliation with amsoil (even though the independant labs that AMSOIL uses don't either), and they had an article comparing a number of oils from mobil one, royal purple, redline, amsoil and a few others. They came to the same conclusions; AMSOIL is superior. Hell, look up blackstone laboratories various tests and you'll find the same. If you don't want to like AMSOIL then just keep using MOBIL ONE, it's still good oil. AMSOIL is just better, period.

 

I looked at all the links you posted, I read through a couple, and I really don't see how most of them are relevant. ???

You have just made the same point I was trying to make. Maybe Amsoil is better, but according to thier own test reports, it's so marginally better it's insignificant, so who cares? People on this website are implying it's magnitudes better, when in fact, according to Asoil's own testing, it's not magnitudes better.

Also, they have the same test report giving two different results. One test pubilished by Amsoil in 2005 says Mobil 1 had a .55mm scar depth, the other test published by Amsoil in 2007 says it's a greater than 1mm scar depth. Which is correct? I believe Amsoil is just publishing the information which makes them look best, just like any other company would.

Sti2EvoX: Maybe it was a third party independant lab, do you know for sure? Which lab was it? I've never seen the name published, and I have tried to find it. The fact that Amsoil pays for the test, influences the results of the testing. It does, you can argue all you want that it doesn't, but in fact, it does. Also, do you know if Amsoil published ALL the information from the testing, or only the info that makes them look better? Companies never publish info that makes themselves look worse. There is always some info held back from the marketing / sales groups. Mobil doesn't have to spend money priving thier product, it's already the standard which the other companies compare themselves to. I looked up Blackstone Labs and the Fast Fours and Rotaries testing, none of it is repeatable or scientific, and none of it gives enough in from which to draw a conclusion. Stating that "Amsoil is just better, period" is your opinion. There is no fact to back it up. If you want me to believe it, you need to provide solid evidence, not just the vagueness which you have already contributed.

 

Im using Full synth Mobil 1 10w30 since day one, almost 70k on the motor, no problems, cams were installed when the car had 25k on it lol, now i switched to 5-50. just because of the milage on the motor.

I did royal purple ones, and i could hear my lifters like on my DSM, so i switched back to mobil, oem' ftw.
