Notice the use of the word "including" when referencing PAOs. They did this because they could NOT truthfully say "a majority".

I pulled the following from their website. Again, they use the word "including".

M1 is a fine oil...nothing wrong with it at all. It is just that ot os 3 times as expensive as it should be. Some people will pay $600 for a pair of shoes just because of the name that is on them. Others pay $6/qt. for motor oil because of the same reason.

Question:
Response to Claims that Products Contain 'Mostly Mineral Oil'
I've seen claims of gas chromatograph analysis of Mobil 1 Extended Performance 5W-30 SM dated 10-06 that state it is "mostly mineral oil". Realizing that you cannot divulge your exact formulations, what do you say to the critics that claim you are using a high percentage of hydro processed mineral oil in Mobil 1 instead of the more expensive PAO or polyester base stocks?

Answer:
Just like other companies, we do not discuss our product formulations for obvious proprietary reasons. Mobil 1 Extended Performance is formulated using a combination of high performance fluids including PAO, along with a proprietary system of performance additives. But in the end, it is also about performance. Mobil 1 is used by more Original Equipment Manufacturers than any other oil as factory fill in their vehicles. Also take note of the kind of testing we put our product through, including the Las Vegas field testing we recently completed. The Mobil 1 technology is also tested each weekend on the race track. In fact, more than 50 percent of all NASCAR teams use Mobil 1.

Mobil's site flatly says:What more can they say?

 

Did you forget about the whole Mobil vs. Castrol lawsuit that started this new definition of what is and what is not a synthetic oil? Castrol was using a G3 base which Mobil said was not truly a synthetic base, then they SWITCHED to a G3 base after the lawsuit, when the courts decided G3 could constitute a synthetic base. Of course this makes no sense since G3 comes from dino juice and by its very nature could NOT be considered synthetic since it comes from nature.



And dont get me started of Mobils funding of global warming skeptics, shady foreign business practices, the Valdez oil spill, their human rights record .......

no sense getting oil anytime soon. need a new engine to put it in first. lolz. blew a valve. just might as well replace everything.

 

How did you do that?

 

Mobil-1 for me. This oil will last for at least 14K miles. I have pushed it to over 15K miles on one change before. No side effects aside from a slightly rough idle. Once changed, was smooth as butter.

 

How can the oil affect the idle?

I have no idea but it sure does. When I change the oil there is a definite difference between the dirty and clean.

There have been test done on Mobil 1 and they noticed the same thing especially when it starts getting close to 15K miles. The test showed the oil still holds up for that long, backed by a chemical analysis.

 

trying to push a little too much out of a weed wacker motor, but yea took the head off the other day and saw that the one of the intake spring was busted.

and question about how oil affects idle? i'm wondering that too. i'm running mobil 1 and it has been working great. but since i've used it my idle plays. what i mean is some times it goes below 5k and gets rough than comes back up. and than it does it again after a few seconds. it does it pretty much everyday now. so whats going one. is it my oil? i'll try new oil and see. but i changed new plugs so that wasn't the problem.

I actually mean that when the oil gets dirty it will idle a little rougher.

My car has always idled a little funny, sometimes dropping the rpms to the point I think it will stall, especially when the AC is on.

Is there any third party information on the different synthetics available. I never really trust what manufacturers say about themselves, they want to make a sale.

Please post links if you have any.

In my opinion this is the best!

Take a look around in the forums.

 

WHY???Mobil 1 is all that engine will ever need to go 300K plus miles.

 

checked out mobil1.com. it IS IN FACT made from PAO base! can now be used in any car from ZERO to over 70k miles. indeed, the list of autos using it as OEM equipment is quite ompressive!

 

I thought that this tread too wasnt going to start into a ____ing match. I had my hopes up until this page LOL. But the question is a loaded one, as everyone has their own different opinons.

I have used Mobil 1 for well over 15 years now, and havent had one problem. Thats countless oil changes on several different cars all from 100K+ miles to brand new. More recently i switch over to the Mobil 1 Extended Life and i get 15K miles out of it. At Wal-Mart is only a few dollars more ( still under $30 ) for 5 quarts and i use a quality oil filter. I use the blue PureOne filters, they run about $7 a pop. They have a rubber diaphram that keeps some oil in the can during start up, which i like.

JMO.

 

The Purolator PureOne are supposedly one of the better filters for filtering small particles. Unfortunately, they're also supposed to be fairly restrictive which means they'd be in bypass a lot of the time. I've been using them too with regular Mobil 1 and 6m/5k changes.

I think the next oil change I may try some Amsoil oil and their Ea oil filter. The filters are supposed to be the best and I haven't heard any complaints about the oil. With the filters around $16 and oil around $8/qt, it's 1.5x to 2x as expensive for a change. Worth it if I were to follow their 1yr/25k mile service or 1yr/15k severe service. Still undecided though...
