Will this oil actually go 25000 miles? I am yet to see a UOA close to 25000 miles without a lot of make up oil replenishing TBN. The reason I am asking is my wife drives about 25000 miles a year and this really catches my attention...however her truck does not burn a drop of oil in 5000 mile OCI that I am practicing right now and I mean not a drop. So without any makeup oil do you really think it would hold up for 25000 miles? I am kinda leary about it and am still thinking about running it however changing it twice a year, right before winter and right before summer, that would be 12500 mile 6 month OCI.

Is there any other oil/filter combo that would hold up for 12500 mile 6 month OCI with no makeup oil? Maybe Mobil 1 EP and filter?

The SSO is actually rated for 35,000 miles under the right conditions. If your wife drives 25,000 a year, and the engine is tip top shape, then yes, it should be no problem.

Just for piece of mind, first do a UOA around 13,000 miles to see how its fairing.

IMO
 
Engine is tip top and she drives 50 miles round trip to work everyday all freeway but the rest of the miles are all little short trips to the store 1 mile, bringing kids to school 2 miles ect ect. So what kind of conditions would that fall under? I think I am going to run the Amsoil and filter for 6 months and change it as well as get a UOA and see where we stand. If the UOA looks bad and blackstone says it did not have much life left in it I will send the report to Amsoil just to see what they have to say.
 
My friend is running Amsoil SSO in his Toyota Matrix for 25K MILES without issue and has been doing for quite a while now.

He changes his EAO oil filter half way between.

I have asked to do a UOA for him but he doesn't think it is necessary.

Not THAT much difference between them....both will use a complex PAO/Ester base oil; both have overbased Calcium at about 3500-3900ppm; neither uses moly or Boron in their add-pack...HDD is much thicker than SSO, but that's 'biggest' difference between them.

So, okay, maybe they aren't the same oil or application, but there aren't many 'true' 25k, no top-off, straight runs of any Amsoil on here. Wanted to show that an Amsoil product COULD do it.....

Point taken...I am still going to do a 6month UOA and see where I stand, if it looks good I will run it for a year or 25k.
 
When you do your UOA, don't panic, the high TBN Amsoil oils start out with falls quickly to the 4-5 range but then hangs on for a very long time in that range I have found.

It's not linear to the mileage... Just something to keep in mind.

So in the first 6 months it might fall 6 points on the TBN scale but then in the last 6 months might only fall 2 points assuming the same miles are driven in both 6 month periods with the same driving patters etc.

Sounds like a great plan. I'm all for long drains, but I'm starting to see the merit in 6 month, 10-12k drains...a year is a long time, and a lot can happen in that time that you may not catch...ie, air filter rips/leaks - if you change at six months, you get the abrasive Si out, instead of it being there for a year. Same for a coolant leak...etc....
 
What kind of viscosity could I expect out of the 0w30 after a 250000 mile run...just a guesstimate? Would it resemble a 20w50 lol!
 
Actually the 0w30 seems to stay in the 30wt grade pretty well from the UOA's I have seen. If you have excess fuel dilution in this time it will fall apart though...

250000 miles? Not recommending that.

It would still be in the 30 wt range with 25K.

The thing you should absolutely know is that you don't just dump SSO in and drive 25K. You should do it in phases. 12K, 20K and then 25K. You have to realize the first OCI, you will be dealing with whatever oil and material is left behind from the previous oils.

That is why I am going to run 6 months and get a UOA...If it looks good I will extend it. I use to so 3k oil changes and since we have owned this truck I do 5k changes with mobil clean 5000, that was a big step for me...12.5 and 25k? OMG I dont know if I will be able to sleep at night. Money is not really a big deal what I dont like is crawling under her truck every 2 months to change the oil...twice a year would not be bad so I think I might just run the Amsoil and filter and change it twice a year spring/fall and call it good. I am lucky though and have an auto parts store here in town that sells Amsoil and for 5qts and filter will come to $75.
 
I guess I am still a little old school, just the way I was taught. No way under any conditions would "I" run any oil 25,000 miles. I would change the oil in May and November or at 12,500 miles, and that would be the extent of my extended drains. To many things can go wrong. JMO Fire away, I took cover

I think Pablo is saying that you should dump the SSO at 12k, then reload with it for a longer run.
