For those that run Mobil 1 oil...

I am not going to run their oil anymore.


Not because it is 'bad' oil, but because it is grossly overpriced now.
Scroll down to "controversy"...they made the Wikipedia for going Dino basestocks....

Mobil 1 was introduced in 1974. In 2002 Mobil B1 introduced "supersyn" anti-wear technology, followed by Mobil 1 Extended Performance in 2005 which increased the use of this technology further.
Controversy
In 2006, the results of a gas chromatography test on Mobil 1 EP 5w-30 were posted by an industry expert on the popular motor oil discussion website BITOG (http://www.bobistheoilguy.com/";). It showed the oil to be primarily composed of a less expensive, Group III hydroprocessed mineral oil. Until this time, Mobil 1 was believed to be a true synthetic, utilizing a Group IV (PAO) basestock. The release of this information has led to a backlash against ExxonMobil's lubricant products in many automotive communities. Ironically, in 1999, Mobil fought Castrol's change in formulation to a Group III basestock in motor oils being marketed as fully synthetic. Mobil claimed that Castrol was decieving their customer base, while degrading their products. The National Advertising Division of the Council of Better Business Bureaus eventually ruled that Castrol could continue to market their Syntec line as a fully synthetic motor oil. ExxonMobil currently refuses to comment on the primary basestock of their Mobil 1 series of oils.

Yeah they are spendy. I usually just throw some left over cooking grease in my car anyway. :p

Luos, why not switch to Royal Purple?

Isnt it dyno proven to increase horsepower?
Ive been thinking of switching from Mobile 1 to RP.

Everything is dyno proven these days. I haven't seen the dyno sheets anywhere.

But, I just go with good ol Quaker State.

Quaker State? you pussy!
go to the royal purple website and look at thier videos from Horsepower TV.

Quaker State.....:disappoin

Nothing wrong with Royal Purple.

Other than price.
Been shown to be very similiar to the VP oils I ordered, and Pennzoil Platinum.

So basically Mobile 1 synthetic isnt really synthetic?
I read over it but I didnt know there where grade I II and III of synthetic oils!
So is Royal Purple more synthetic then Mobile 1 and is Motul more synthetic then Royal Purple?

Ohhhhh, my aching head!

Something like that. :lol:

Basestock I, II, III aren't fully synthetic. Although apparently they are allowed to call a basestock III a synthetic.
IV and V are fully synthetic.
At least that is how I understand it.

Mobil 1 is still a fine motor oil. Just not worth the price we have to pay for it.

AHHHHHHH, im glad im getting rid of this Mobil 1 again. 1st 3k miles with it, and i dont like it as much. i dont know why. valvoline synpower is what i started with, and is what im going back with.

Interesting.

I use royal purple, it's not too expensive, cheaper than mobile 1. The Purple does the job and it makes the cars run nicely. I've tried Motul in the Jetta and didnt like it much, the oil seemed too thin for my liking.

I use Castrol Syntec german blend in my ss and the Castrol synthetic blend in my truck. I've had zero problems out of the truck burning oil in 8 years and 155,000 miles......and I'm by no means easy on the truck. :grinno:

As I understand it...that German blend isn't made anymore. :banghead:

I dont know if it really adds power but the Porsche only gets RP

Ahh but your mileage is skewed... 155,000 on the chassis, but not on the motor.

I use AMS Oil, better than even royal purple but not as readily available. If they were available like RP, everyone should be using it. They are the true pioneers in sythetic lubricants. I've done my research for hours apon hours deciding what to put in my Mustang after the 331 was built up. Expensive, but you get what you pay for.

I read that Amsoil doesn't have the wear properties that other leading synthetics use.

I know a very knowledgable (sp?) gentlemen that gets Amsoil for free...and doesn't use it in his performance vehicles.

Not saying it is a bad oil. Just passing along info I have heard.

yeah I'd rather not use it in my RX-8, i would rather go with a thiker oil like RP cause the 8 eats oil like crazy

i thought you weren't suppost to put synthetic oil in teh rotary? voids warrenty or something.

I used to run mobil 1 in the eclipse when i had it, but it caused horrible lifter tick due to the detergents that are in it. I'm a service advisor at a GM dealership and i can tell you most people wont use mobil 1 just because they dont want to pay $80 for an oil change, it's way to pricey now.

Horrible lifter tick eh? :mad:

Jesus.

5 quarts Mobil 1 5w-30 = $22
ACDelco filter = $5
15 minutes of my time to change it myself.

it's very very debateable...the reasons for using regular oil is because they said it lubricates the seals better, but that is based on information that was provided over 10 years ago, with the Fc's. The seals that are used in the renesis are different and stronger seals, there have been people running synthetic in the renesis and currently have well over 60k miles on them.

Also RP is the only synthetic oil that is reccomended to use in rotaries because they themselves have been using the oil for over 10 years in thier own FD's and have continously been doing thier R & D about the rotaries so their oil can always be used.

I find that very interesting. Did you happen to read that on the internet somewhere? If you did you mind sending me a link? I try to keep an open mind about oils and all the so called "independant" tests out there. But when i was researching RP, AMS, Mobil1 etc. a few years ago. I couldn't find anything that said negative stuff about AMS oil. In fact I found a VERY good comparison between the two using an LS1 engine even. Now like i said, i keep an open mind about Independant tests and everything but so far to date i have found nothing more complete then that test. It compared AMS oil directly with Mobil 1.

It isn't that it adds horsepower. It reduces friction thus reducing drivetrain loss. On Horsepower T.V. and Trucks they tried out the Royal Purple on the dyno and freed up more power than I would have expected. This also means better gas mileage.

When it warms up my tranny, t-case, and diff are all getting RP.

I am not going to run their oil anymore.

I wouldn't put Penzoil in my car if you gave it to me for free. Any half ass mechanic will tell you Penzoil makes crappy products. In fact a buddy of mine's dad found out his used car had it inside, and immediately took it out for another name brand oil, eventhough the car wasn't due for an oil change.

That said i'd probably use Castrol Synthetic or some other brand of synthetic motor oil if Mobil 1 becomes too expensive.

90redgt, I don't have any links. It was discussed with someone that takes maintenance to a whole new level. :lol:
He says he gets Amsoil for free from a sponsor and still uses something else.

Granted, he doesn't pay much for the other oils either. :lol:
He recommended the VP synthetics to me. In turn, I ordered a case.

www.Bobistheoilguy.com
Not Bob that I have been speaking with, but someone that is on that site since it showed up.

From my guy...
Short answer...no Royal Purple is not "better" oil than Mobil 1. However it depends on your viewpoint here...RP uses heavy doses of Phospherous as a additive.....this is good for cleaning etc. Mobil 1 5-30 thins out to a 20 weight after less than 500 miles.....the friction modifiers are superior in Mobil 1 but the add packs are superior in RP (rust/oxidation/engine cleaning agents etc)...so if you look at Used Oil Analysis you see Mobil 1 has better wear results after 5000-/+ Oil Change Intervals but RP provides better long term protection on engine tear down and ring wear
Looks like he used to run Amsoil. I think he still does in a few of his vehicles.

Not the first time I have heard that.

Apparently this new Pennzoil Platinum is a very good oil though.
