Why do some of the Newer oils have a low TBN #

Good question... I'm not sure. If I had to speculate it would be that it holds it's tbn much better than typical oils. Look at that VI! That's one heck of a cold weather spec oil and I wouldn't hesitate to use it if my car spec'd a 20 weight.
 
HaHa, I like the warning on the page you provided that reads, "Do not drink the oil. It causes nausea and diarrhea." Who drinks oil?

The crazy arm wrestler on Over The Top drank motor oil, LOL.

How about the lard Arse on Stand by me that drank castor oil, Classic
 
here is a quote:

Storage Method: Seal the container tightly after use in order to prevent dirt, moisture, etc., from entering the oil. Store in a dark location. Avoid direct sunlight.

..could you please explain further by what you mean by "stable"..generally speaking..I always thought the higher the TBN number, the longer the oil can stay in useage..would this Not be true to some degree thus making this oil not suitable for long term use
 
Viscosity and TBN aren't related. One is the thickness of the oil, and the other is it's ability to resist becoming acidic.

A higher TBN oil will retain a neutral Ph level longer. I don't know why some 20 weight oils don't have a higher tbn. But, it has nothing to do with VII's AFAIK.

Hopefully someone with more info can chime in, but one would think the opposite of what is posted here. If an oil were incredibly shear stable, one would think it would be well suited for long oci and therefore would also come with a high TBN (which all long drain oils do).

TBN refers to additives that fight acids. Some oils are just less prone to acid formation, so they don't need as high a TBN. A lower number will do just as well. That's one possible reason.

Another possible reason is that the oil is intended to be used in markets where gasoline does not contain ethanol. This also translates to lower acid formation, hence less need for a high TBN.

A third possibility is that the oil is formulated to be friendly to the emissions systems of modern "clean" diesel cars. That entails minimizing certain additives, which can affect the TBN.

It depends on the formulation. A high initial TBN does not ensure extended drains. Amsoil ASM 0w-20 has a high TBN of 12 and is formulated for extended drains. Schaeffers and redline have considerably lower initial TBN's but have been showing extend use capability by TBN retention.

Retention IMO is more important then a higher initial TBN. If you can find an oil that has both then it could be run for a considerable length of time and be effective.

ENEOS is made by the Nippon Oil Company; it's their house brand.

But Nippon Oil also make the Toyota Brand 0W-20.
There are a few VOA's and one UOA of the Toyota 0W-20 and it's spec's are even more impressive than ENEOS.
The VI is 214, the TBN is 6.7 (determined by Dyson Analysis).
Toyota has just extended the recommended OCI from 5,000 to 10,000 miles.
 
Many of the newer Euro oils are low SAPS formulations that have lower TBNs.

A point that is not commonly brought up here, is that the ability to do long drain intervals is also dependent on fuel quality.

explain this. Been here 6 years and never heard this...

Tooslick discussed this a while ago in the UOA section. I'll search and look for some of the posts and post them this weekend.
 
It certainly has to do with gas with ethanol vs without. In fact, an oil's ability to retain the extra acids ethanol blends create is part of the move from SM to SN.

..I will try to find the UOA of Toyota's 0w/20..would Honda's oil be the same thing..

According to the VOA the Honda and Toyota oils are different. IMO the Toyota oil is the better of the two based on VOA. I'm sure UOA will be coming in since both oils seem to be gaining interest on the board.
