comments? Blackstone labs says run next batch out to 6,000 miles based on these results.

[Falkdesigns]

The latest Mobil 1 commercials guarantee their oil to 15000 miles. Guarantee.

I should have my analysis back soon on Amsoil that I had in there for ~ 8000 miles.

I'd have to pull out my old Analysis report on Amsoil from the Civic Si I had to compare numbers which is at home. Doesn't it have a table, and tell what low and high numbers are? I get mine done at Oil Analyzers Inc. and they offer very self explanatory test results.

It's a new offering, not just them changing the recomendation on the existing oil

Mobil 1 Extended Performance You've never seen an oil like this before. Mobil 1® Extended Performance is a new high-endurance motor oil with 36 percent more anti-wear additives and 37 percent more cleaning agents than current Mobil 1 formulations. It is a fully synthetic formulation that helps extend engine life, reduce oil breakdown and minimize engine wear -- all while helping to keep your engine clean. Improvements that add up to exceptional protection for 15,000 miles. Guaranteed.

Amsoil has been recomending a 15k / 1 year oil change interval for years. Finally Mobil 1 is trying to catch up . I would run Mobil 1 if I didn't feel that Amsoil and Redline were superior products, and if they weren't readilly available to me.

[Rex]

They may be "just" catching up, but I wonder how the price compares?

I can't find pricing for the new Mobil 1 Extended Performance online at any of the Pep-Auto-Advance-Blah-Blah-Blah places.

I'd rather just change mine every 3 months and be done with it.

[Falkdesigns]

Why when an oil mfg. gurantee's thier oil for 15k someone would change it after only 3k boggles my mind. Synthetic oils do not suffer the downfalls of Dino oils. There is no thermal viscosity breakdown. You merely should change the filter at 6 months, and top off the oil. I've seen first hand the analysis results of Amsoil that had 10k on it, 3 auto-x's and numerous abusive canyon runs in the 2 hour range. It came back "suitable for continued use". Once again, this is an argument I can't win with you guys until you try it yourself, and get your own analysis results back. I for one, have all the proof I need.

I think 7.50-8 bucks a quart for Amsoil and Redline is pretty good. I bet the new Mobil 1 will be at least 6 bucks.

[elwesso]

The problem arises is that, while the oil is still is still fine as a lubricant, it is the non soluable things that the filter cannot even get, but can still cause enough friction to cause wear.... Hopefully Fred can clarify this, but I know he said there are things called VII's or whatever, and those are the viscosity enhancers (that allow it to exhibit a 10 weight cold and 30 weight hot) that break down and cause varnish.....

Its like fighting a never ending war, no one will every be absolutely right that everyone will agree on. Personally I will aire on the side of caution... im going to change my oil at 4000 miles, and may run my redline next fill slightly longer...

The bottom line is, even mobil 1 is cheap... $30 for a case over the course of 3 months isnt really that big of a deal...

Good info Qship, im going to get an analysis done on my mobil 1 0w40 and see how it does....

[PoorManQ45]

I think 7.50-8 bucks a quart for Amsoil and Redline is pretty good. I bet the new Mobil 1 will be at least 6 bucks.

At walmart it costs ~$4.75 for a quart of the 15k Mile Mobile 1 synthetic

Unfortunately for me, they stopped carrying the regular Mobile 1 synthetic, SO it's back to Supertach for this Poorman

[PalmerWMD]

I am always skeptical of a formulation change that advertises "now longer OCI's", even if the formal is changed, there is no freee lunch.

The extra addtives to ensure reserves for a longer OCI, must come from somewhere. if you ahve more detergent the nyou are taking away from somwhere else

I imagine perhaps this forumulation may have less of some other additives, which ones I dont know, anti foaming? or anti rust? or less baseoil and a higher %age of the total formulation that is not lubricant?

its coming fcrom somewhere, I'll stick with the regular Mobil1 or one of its competors

Fred..

[PoorManQ45]

For some reason I was thinking that exact same thing. They're still selling the oil in 1 qt containers. SO you can't increse the percentage of one additive without decreasing another. Hopefully they didn't lower the anit-foaming and/or anti-rust as you suggested

[qship96]

so,maybe you get 2-3 teaspoons less base oil,for increased detergents and additives to get a longer lasting,more robust oil. pure guessing without analysis to tell you how it is holding up IN YOUR PARTICULAR ENGINE!

Precisely.....

And IMHO, you cant (cant) go wrong with M1 syn at 4000 mile intervals, whatever the case is.....

[Falkdesigns]

That's true and in my case, all the contaminants they measure for in PPM's were so far down the scale, like near the bottom, that I knew that the oil was still doing it's job. Amsoil & Redline have recomended extended OCI's for YEARS. Mobil 1 is the late one to the game.

[qship96]

Falkdesigns,along with looking at wear metals,insoluables,viscosity,etc you must also look at the TBN to determine when to change the oil. this batch of mobil 1 actually held up better IN MY ENGINE than the Redline oil I have been using,according to the analysis reports for my engine!as much as i am a fan of the redline chemistry,it didnt do a superior job than mobil as far as measurable results.I may try a blend of these 2 oils and measure the outcome,as i have 19 quarts of redline on my shelf!

[Falkdesigns]

That's pretty wild! Well, I have always used Amsoil and this is the first time to try Redline. I got the Redline for *nothing* so figured I'd use it for now. I should have my analysis on the Amsoil I had in for 8k very soon as I sent it out about 10 days ago.

[PalmerWMD]

the oil<cant> be more robust if there is less baseoil in it.

One sign that Mobil attempted to address this at least in part in the extended formulation is that their 40 weight is a 10w-40 not a 0w-40 like their other 40 weight.

reasons are obcious less room to put VII's as other addtives take their place.

Fred..

[qship96]

Fred,I think you are making a huge assumption that the oil CANT be more robust,without actually testing it.I seriously doubt mobil would risk its excellent reputation with this new formulation,if they didnt believe it would test out to be better in actual use.

[PalmerWMD]

qship:

I am not saying its a bad oil, its probaly an excellent oil.Its just that there is no free lunch, every advantage has to be paid for, by a disadvanatge elsewhere in the formulation, if equal chemisties are used.

Since the normal Mobil1 is high end as it is, there is not much room for improvement in the chemistry, so trade-off will have to be made somwhere in the formulation.

The only room for improvement would be switching to an even better base oil ,which will enable saving VII's out of the formulation ,which will make more additives of everything else possible.

This is the model that synthetics have over non syns.

I suppose Mobil could go from a group 4 PAO, to a group V like redline, but improvements are likely to be incremental and in any case expensive for the consumer.

Plus ExxonMobil is the biggest producer of PAO's in the world ,wouldnt make sense for them to drop them in a major consumer oil.

For example in Europe you can get castrol SLX and castrol SLX longtec.very similiar synthetic oils, except the Longtec is optimized for long drain intervals.And it works as advertised, <but> the HT/HS an important value in performance applications, is noticably lower, than the regular SLX (which is repackaged and sold in USA as Castrol Syntec 0w-30 ACEA A3, btw)The longtec doesnt make ACEA A3, but ACEA A1 instead, a lesser spec in many ways.(Tho it <does> last longer)

Fred..

[qship96]

Fred,I hear what you are saying!I personally would never attempt 15,000 miles with mobils new oil,or ANY oil actually-my interest,with mobils claim to get this extended mileage,they vastly increaded detergents and additives,is whether it will show better analysis results then regular mobil 1 for say the 5-6000 miles i normally go per change.I think my analysis this time was fantastic with regular mobil 1,just trying to squeeze out even better results,if at all possible-ps the results above were better than my last 5,000 run with Redline!

I agree your result is very good.No reason to change what works, I kind like the current oil formulation of Mobil1

Fred..

PS: my favorite Mobil1 eve,r was the mid 90's formulation before the switch to SL, the SJ (or w3s it the SH spec mobil1) formulation in Mobil1 15w-40, no VII's at all optmnized for proytecting against wear only with scant attention paid to fuel economy and none to catlytic converter protection.A 15-w40 optmized as a gasoline not Diesel oil.

[qship96]

Fred,I am considering blending mobil 1 with redline to get the best of both-i had hoped using streight redline would have posted superior results to mobil in my engine,but it hasnt,much to my surprise,being a ester based oil.iam hoping the dose of moly and ester,combined with mobil will show a strong result-anyone with the 350z`s having any superior results from these synthetics?

[PalmerWMD]

I would not blend Mobil1 with redline ever.

they different base oils used need different additive chemistries.

Better use one or the other redline is an awesome oil with incredible stability is hard running. Mobil comes very close and is 20-50% less depending on were you buy either.

For you i would recommend trying the new SUV Mobil1 oil in 5w-40 as its high detergentand higher viscosity for your nonnew engine.

But then again, why mess with success, clearly your current oil is working great.

Fred..

[PoorManQ45]

Plus ExxonMobil is the biggest producer of PAO's in the world ,wouldnt make sense for them to drop them in a major consumer oil.

On a side note, ExxonMobil is now the largest company in the world.

About their 15k mile claim, it probably is true, but what actually happens to the oil after 15k miles? Won't the filter be in need of a replace at ~7500~10k?

I personally would recommend that anyone, except maybe Geo Metro owners , go 15k miles without an oil change.

Also note that Car manufactures are extending the Oil and transmission fluid to ~7500 miles and never, respectively. Example, GM recommends these exact intervals. Can you follow their guidelines and keep the engine in great conditions? Yes, but for how long? I would bet that it would be somewhere near the end of the warranty that these extended oil change intervals catch up to you. So, the long change intervals work for awhile, but it will almost always catch up to you in the end.

Fred: Lets assume that the Mobil 1 15k mile oil will indeed be good for ~15k miles... What would the affect on the engine be?

[Falkdesigns]

If an engine fails after warranty because of the mfg's recomendation that you change oil at 15 k, the mfg still will suffer from a bad reputation. The cars life under warranty is NOT all the mfg's care about.

BMW recomends once a year oil change on all their cars. And if you service it at the dealer, even if you want to pay for it, they won't change it sooner. Thier reasoning: you don't need it. Amsoil has always recomended that you change the filter after 6 months, but the oil continues to do an exemplary job.

I've seen the pics of a diesel engine torn down after 250k without an oil change that ran Amsoil and the internals were almost as new. I know some people said well, it's a diesel truck. I tell you what, a tractor trailer hauling as much weight as a house for 250k is under MUCH more load and stress than our engines ever will see.
