OCI, not when but why?

Every fiber of my body is saying this turkey is fully cooked and nothing is going to help. But I thought that several times along our journey only to be refreshingly disappointed.

Kind of thought this was a positive statement. No one is shoveling dirt yet. It took a few OCI's for the last method to respond and it did nicely. No need for a sad face.

First positive is that the usage was pretty linear. Second is the end point color of the oil. I'll be changing oil in the next day or two.

Looking at the Mobil 1 FS Euro 5W40 newest formula SP as a lower ash, low cost replacement for the Shell Rotella T6 5W40 that has a bit of ester. That is after I've gotten what I think can be had from this current choice.

Are you saying the new Valvoline oil is not working as advertised or has done all it can do? You did try it right?

No, not saying anything yet. I'll keep up with the Valvoline R&P for quite some time. A lot of things are possible, so I was just thinking out loud on the keyboard.

It historically has used less oil on a *W40 so keeping an eye out for a lower ash replacement.

Yes, it could be the usage will slow enough I just keep using this one. Who knows. Only giving enough time for the data to speak can answer all the questions.

I just opined in one of the earlier post it is also likely the rings and bore and just done and nothing will restore it. :dunno:

A good guess, a what if, precedes a hypothesis. Very Grumpy like, eh?

Looks like they updated the photos on their website. They're a bit clearer. Still limited in terms of what they're sharing.

I wish they would define the length in miles or hours of "Four Changes" which is what they say it takes to bring it back to new.

What do you think of TEOST 33C?

I don't think about it at all....because.....I don't try to see how close I can run to failure to save an illusional buck. I suppose it may have some meaning to those looking in the broken toy box to find the least broken toy. :dunno:

I just don't shop in the 'scratch and dent' isle.

Do you find it humorous at all that AMSOIL chose to compare themselves to oils that do not meet the ILSAC GF6 spec? Try again with those that do. :idiot:

IF they are the only one in that space, then good for them but it's still a product I haven't a need for. Because? I didn't start in the broken toy isle creating a need for it. :rolleyes:

:rant:

TEOST is an oxidation test. It’s meaningful for turbocharger deposit formation.
Here’s some more of our 2009 testing on Mobil 1 5w30 EP showing the relationship between TEOST 33C and MHT and TFOUT compared to NOACK.

Blah blah blah. What are you even stating? Hand waving.

If he’s wrong about something in particular in that video I’d genuinely like to know.

Personally, I think the person who buys a new Toyota and goes 10,000 miles on 0w8/0w16 before the first oil change is the real idiot, not him.

This ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I'll extend that to any oil and any manufacture.

Look, in the 50's and 60's a 100K was time to call in the gut wagon for most consumers vehicles. MOST but not all. But enough to create a narrative. There were some as early as the 30's who could get things to last a lifetime. Thier life time.

Manufacturing has improved to the point that we now have an average life span the legal system now terminates at 150K. That is not allot of progress. But some still can get things, even badly engineered and manufactured things to last as long as they wish. Once again, the fist creates the narrative.

Show me a scholarly peer reviewed study where early oil changes do NOT lead to a longer engine life.

Some of these replies are really humorous. I would venture that a person who changes their oil around 500 miles probably keeps their vehicle until the wheels fall off. You wouldn’t see their vehicles in the used car market. So using that logic most everyone else probably follows the manufacturer recommendations. Keeping that in mind everyone else is driving a time bomb. No not really. The longest lasting vehicles, Honda and Toyota recommend 10K oil changes. Most of those buyers tend to not only hang on to their vehicles. When they buy their next vehicle it’s usually the same brand. So those people would question who’s the idiot. As far as 500 mile oil change. I never did it. In fact my pulling rigs that traveled 50K miles a year. Usually went 25K miles on Amsoil before the first oil change. Those miles couldn’t be harder. I don’t do that anymore mainly because I don’t drive those miles anymore. And I have more time being retired. I see the wisdom now of changing the oil by 5K miles. Mainly because of driving habits now, less highway miles. If I was ripping the highway I’d go longer.
