I read the running thread, quite disheartening that Mobil would go backwards on the formulation but keeping the price steepest about syn fluids inspite of making $40B in profits.:mad:

Well as the thread details Penzoil Platinum is a great choice and when on sale at local stores, quite a bargain!!!

Being an avid Mobil 1 user for the last 15 years, this is very disappointing. It looks like Mobil finally caved in to Castrol's definition of the term "synthetic" (ie: Hydrocracked Dino), and severely downgraded the quality of their product. With the premium price that they are charging for their oils, one might as well pay a little bit more for the real stuff, Amsoil/Redline.

Amsoil has gone to Group III (hydrocracked dyno) in only their XL7500 motor oil which continues to have a 7500 mile drain interval. Their other oils (Amsoil Original Synthetic, Series 2000, Series 3000) all remain true synthetic PAO based with ability to go to extended drain intervals. True PAO's are similar to liquid low molecular weight plastics (ie polyethylene/polypropylene). Group II and Group III oils are just "tweaked" dino oil.

Has the performance gap between Group III and PAO's narrowed? YES, but there is still a gap which is partially compensated by using additional additives. Unfortunately, you can only keep up to a certain level of additives dissolved in the oil... and the more the processing, the less the solvency.

I always liked M1 since my dad had switched to it LONG ago. I've seen the difference in how clean motors running it are over the years. I put it in the Sequoia after about 3 oil changes when new and had planned on staying with it. Amsoil is not easy to get all the time. For the price difference I might switch to something like the Penzoil Platinum or some of the others discussed on bitog. I think the M1 is still probably an excellent product but I'm not going to keep paying premium $$ for oil that isn't premium anymore.

all of you oil nuts should have to read every one of these posts.
i did.

So far only the EP oils have been shown to contain Group III. Ignorance is bliss, but the "classic" formula is what I am using until I see that it is also involved.

Did you know Mobil EP (15K mile stuff) costs more than Mobil1 Synthetic?

The threads in general talk about both the Mobil 1 Syn and EP formulations that are going the GrpIII way.

Yeah, the classic formula has always been a better value anyway IMO.

Why is everyone so quick to throw Mobil 1 out the door since one guy says he ran some test and found certain results? First, there is a ton of BS on these forums that everyone takes to heart...especially considering they have no idea in which context the message was written. I have been on those "bobistheoilguy" forums and read what everyone is saying. I think its funny how many people have jumped to the conclusion that mobil 1 is no longer worth the money. If I posted information on Redline, Royal Purple, or Amsoil that said the oil were based from Group III stocks, would everyone just believe me too? Everyone needs to settle down...especially considering how good Mobil 1 oil has been to everyone over the years. For years it has provided great lubrication for your engines and enabled you to go hundreds of thousands of miles. If the oil was so crappy, do you think so many manufacturers would be putting it in their vehicle from the factory? Lets get everything back into perspective!

It is because the one guy you are talking about has impeccable credentials.

somehow i have survived my entire life w/o mobil 1.
never had an oil related engine failure. the rest of the vehicle always fell down around the motor. air cooled motorcycle engines are a different matter. synthetic all the way in that case

Tones,
you know the individual that is making these claims about Mobil 1? What are his credentials? I noticed on the "bobistheoilguy" forum, the person who made the claims joined the forum in 2006. How long has that forum been around? Last question, are you personally standing behind his findings 100%?

I don't know him, but several members of BITOG do. His credentials were posted on the board. Perhaps I don't understand your question, but why would I stand behind his findings? He does that himself. Many people have started or passed on rumors like this in the past, but were ignored. Here is a guy who knows his stuff and makes this claim. It gives the claim more credibility.

For you folks that are using Mobil One, are you willing to pay more the same formulation? The feedstocks to make the PAO basestock are becoming harder and more expensive to find. What makes you think that the Group III is not a synthetic- it's still a liquid AND gas to liquid technology. There are advantages and disadvantages to ALL of the known lubrication basestocks and the PAOs are no exception. Frankly, the mix as I see it will probably mean lower wear metals but only time will tell when UOAs start showing up and the oil is trended. The down side most likely will be that oil change intervals need to be at or near 7500 miles for most engines and that will be determined after the independent UOAs start coming in. Don't go throwing Mobil One under the bus just yet. It maybe a better oil than what you have become accustomed to using.
For you folks that want to question the individual about his claims that Mobil One is a mostly Gp III, here's his website.
