I am going to round the numbers off but this oil is crazy well built and it's not their top of the line stuff . There another , the Ultra thats a step above it . An internet friend TaulPaul oughta just love the thought of making a brew with some of this motorcycle oil.

Antinomy - over 1000 ppm
Sodium 225
Magnesium 650
Calcium 730
Barium 11
Phosforus 3400
Zinc 2560
VI @ 100c 12.5

HT/HS is in the high 4's

This exact formula is offered in a 17.5 cSt 15w-50 and the HT/HS was drum roll ...... 5.5 !

Just thought a few here might be interested in seeing how this oil was built . Sorry , out of respect for the company I will not list the base oils . No group III though

This oil can be has for a little over 6 buck per liter when purchased through a Parts Unlimited dealer .

TBN?

Motorbike, I talked to them today and found out just how muh more they put into their Ultra series oil. I know that I've been asking about different oils on this forum, but I think that I've found a winner for the winter in my vehicle, maybe even a keeper for year 'round use.

You're not kidding when you say that their product is "crazy well built". I also can get it local for $11 liter. I know, very high end in price, but after talking for 30 minutes about the additive package, bases, detergents, and such, I think that this might be the first oil that I will let in my crankcase for 10K miles, or 6 months, whichever comes first. I've NEVER said that about ANY other oil that I've used in the past.

I also would like to hear from TallPaul to see what concoction he could conjure up with it as well!!

New to this forum! I realize that this thread is old and probably dead, but just adding a testimonial from a long time user of Maxima Extra and Ultra......my engines last forever, and a day!

Wow, this surpasses Redline oil. Only thing that bugs me is the sodium. Guess it dosen't matter though. No moly? Who needs moly with all the goodies in this oil. With 1000+ ppm antimony, bet the UOAs come out squeaky clean.

Here is some reading on M/C oils, you will notice this oil is included.

If your favorite brand rates high, you will like the info. If on the other hand, it fairs low you will likely have something negative to say about the info or the company who did it.

Please read it thoroughly..

A Study of Motorcycle Oils

No moly, because these are (ester synthetic) motorcycle specific oils (JASO MA), that can be used in bikes with wet clutches (moly will make the clutch slip).

The new generation of Honda and some Suzuki high performance dirt bike/quad engines (CRF450R/X, TRX450R, CRF250R/X, etc.), are now separating the engine and transmission oils (God Bless Honda!). In these, you have the advantage of being able to run a JASO MB oil in the engine, and a transmission specific lube in the trans (or a JASO MA oil).

If you were to go to the topic header you will see the topic oil is Maxima Maxum 4 Synthetic Extra which is not a synthetic blend . Then , upon a " thorough " read of the link you posted you will find this topic oil was not tested along with the Amsoil synthetic . They chose to test the Maxim 4 Synthetic blend ... for whatever reason and even then did not test or omitted testing of the 20w-50 Maxim 4 synthetic blend .

The Maxima Maxum 4 Extra 10w-40 is a 12.5 - 13.0 centistroke oil made of pao and ester and has an HT/HS of 4.7 ! Noack is undoubtably low also as would be for the 17 cSt Maxima Maxum 4 Extra 15w-50 with a HT/HS of over 5.5 .

As good as these primarily pao with ester oils are they offer two other bike oils on even a higher tier . They are called Maxima Ultra and come in a 5w-40 and 5w-50 for the bikes and are primary ester base oil formulas .

Hope this helps with any confusion as to which Maxima oil is which in topic or Amsoils testing .

TBN?

Second analysis / same engine just in last week and this time with TBN .

TBN was 7.9 after 5 months and a hard 4200 miles . It's a 1 year or 10,000 mile capable oil in many bikes as is the Synergyn 15w-50 and the Silkolene Pro 4 15w-50 .

You can find a VOA for Maxima Maxum 4 Ultra 0w30 at this other site. The most potent oil I've seen period.

According to Maxima, Extra and Ultra have identical formulations, with the exception that Ultra has one additional ester that makes it extremely slick. "This ester does something very special on the surface of the metal"....that's all the additional info they were willing to offer.

In addition, Ultra is offered in some rather unconventional weights.

I run Extra in all my bikes with integrated transmissions, and the transmission of my 450R. In the 450R engine side, I run Ultra.

Another thing I notice is that the very light Ultras (0W10 and 0W30) are not listed as JASO MA! The analysis of these (at the site listed above), shows that they contain moly, so they should not be used in a machine with an integrated transmission.

Not much call for a 0W oil here in So. Calif. anyway!

Since I do have the Ultra in my vehicle right now, if you guys can give me some time to accumulate the mileage for a reasonable UOA of this stuff, I'll post it at that other site as well, since I posted the VOA of it.

Right now, I've got close to 4K miles on it, and was planning on doing the OCI interval at 7K, so I'm over half way there. I feel compelled to say though, unless this stuff comes through with flying colors on the UOA (meaning I could go 15K miles or better), then this stuff probably isn't worth the price of admission ($11 per liter).

Only time will tell now...

Where and why are you paying $11 for Ultra?

$7.25 at http://www.onoffroad.com Even after paying shipping, it isn't anywhere near $11/liter (remember too, that a liter is larger than a quart!).

$6.75 for Extra

It was through a local bike shop. They had to get it in from their warehouse, so it was the retail price of $10.99 per liter.

Thank you so much for the link to this place. I just might keep using this stuff now at that price, as I really didn't want to go back to anything else after dissecting this oil through the VOA. It's built like a tank, and runs "Ultra" smooth in my Honda CR-V. Don't worry, no oil consumption problems for the cat issue with all of the additive package strength.

As I recall, you are running 0W30 (which is actually borderline 0W20)??? Does your bike have an integrated transmission (wet clutch)??? (I don't know much about street machines.) If so, does it bother you that this oil isn't JASO MA, and it contains moly???

I guess that I just floor you then when I say that the Honda CR-V is their SUV vehicle. Yep, I run this in a car.

I do this for two reasons: one, because it is a 0w30 (bordering a 0w20) synthetic based oil, and two, after first reading this post, then conversing with Maxima tech guy personally, and finally getting educated opinions from forums such as this, I said d-a-m-n the torpedoes, full speed ahead and decided to give it a shot.

Now that I realize that I paid almost as much for the first OC with it than I could've for a whole case, I feel really stupid that I didn't shop around online as opposed to just searching for dealers in my neck of the woods.

I really do think that I just might stick with this stuff, but will do the UOA to be on the safe side before running any seriously long OCI's (meaning 10K miles or longer).

So you are just not worrying about your catalytic converter??? (High levels of zinc, etc. can contaminate the converter???) Here in Calif. we have to pass emissions every 2 years to reregister a car, so if I messed up my converter it would be $$$$ to replace it.

I'm not too worried about it, not because I don't care, but because this engine hasn't used a drop of oil since brand new, so the consumption issue that pertains to the cat life is not a concern.

I've even tried 2-cycle lube in the fuel tank for the mileage increase/top end lube issue with today's drier gasoline. No funny smells or smoke, even at an ounce/gallon ratio. Due to winter setting in though (meaning excessive idling, warm up time and crappy gasoline to begin with), I've since put that on hold until spring arrives again.

My inspection is in February, so I'll know pretty fast if anything is up with the emissions systems due to the 2-cycle oil and the lubricant in the crankcase.

The real bargain for the Ultra is the 20 quart pale for 126.00 .

If I can make a suggestion that would be not to waste the money for a test kit this first interval and do a running sample next go around at 6 months , depending on vehicle usage . You will gain nothing from the first test results .

Just one more is not to burn oil "mix" in your gas , with the antimony you really don't need additional upper cylinder " ring lube " protection or the additional combustion chamber deposits if used long term . IMO
