Jay,

There you go trying to cause trouble again...

No additives, only amsoil. Is baron an additive ? I ask cause I don't know.I see that the baron is at 68 with mobil, & I didn't use any adds. with mobil. I thought that the TBN was low with only 5000 mi on the oil, when the oil started with 12 TBN.I don't think I could go 25,000 mi. with this oil, the TBN woulld be used up . SO all will know ,I used a fram xtra guard oil filter on both samples.
 
Amsoil is now recommending 15,000 miles/1 year for the type of driving most folks do.

What is the previous maintenance history of this engine with regards to oil/filter changes? Did you run the Amsoil first and then the Mobil 1?

The difference in TBN's is probably explained by the difference in Calcium levels
 
I ran the mobil 1 st. then the Amsoil.I changed the oil filter when I changed the oil. Why do you think the calcium levels higher with the Amsoil than with the mobil?I don't know any other history with the car. I bought it used with 67,000 miles on the engine.


Noise floor. next ?
 
Both UOAs look excellent and you should be able to run it 7.5k miles on either without issues.
Boron and Calcium are additives in the oil.

Are you using the PH6607 thimble filter?
I'd use a better or bigger oil filter.
 
I agree undummy, baron has to be an addtive in the amsoil cause I didn't add anything else to the oil. You are correct on the fram #. This time I'am using a larger wix #51064 filter.
 
M1 uses more boron than Amsoil. D.Ram, what I was getting at is the wear metals are both so low it doesn't matter. Lab variances are up to 15%. The Amsoil did show better here if one is to be very picky.
 
51334 and 51344 are other options for upsizing the filter.

Was the Amsoil used before or after the Mobil1? What oil or OCI history did the vehicle have before you took ownership?
 
Buster,

If do a VOA of both, I believe you'll find that Amsoil uses more boron than Mobil 1, but that M1 uses more MoDTC. That's from memory of recent UOA's but I believe it's correct.

The seemingly elevated oxidation in the Amsoil test is most likely due to an ester in the basestock blend that's triggering a peak on the FTIR machine. It's also highly likely that you have some cleaning of pre-existing deposits going on here. So TBN retention should improve with continued use of the synthetic lube.

A note on boron:

Borate esters are used to suppliment the decreased levels of Zinc and Phosphorus (ZnDTP) in API/SM engine oils. They react synergistically with ZnDTP to form lower friction, more durable AW films than you get with ZnDTP alone.

TS
 
To add to the comparison, what is the price paid for each oil change?

These numbers are so close that this would be the determining factor for me.

Mobil 1 uses more boron, but probably of a different type. M1 EP uses over 200ppm of Boron. Amsoil only uses about 60ppm.

Bill, you sell Amsoil I can tell. Are you kidding me about the Pb numbers? You can't be that clueless. You could send off both these samples to 5 labs and all 5 will show different numbers +/- 10%-15%. Get a clue.
 
It will be some time b-4 I post again .I plan on going 10,000 on this round of AMSOIL & see how the #s hold up.
 
I don't think the samples aren't switched, but nothing explains the B of 393! That's why I suspected some additive was used. I do think Amsoil has upped the B a bit.

PS Bill - are you an Amsoil dealer or is buster blowing smoke?
 
The lab could have made a mistake on the baron but, I can assure you I don't use any additives in anything I own.If someone would test a unused bottle (unless baron changes with use) then, I guess we would know. I may call Amsoil If I get a chance & ask the tech. guy if he knows why the baron is so high. Is it bad that the baron is high ? Will this cause problems ?
