Boosting Old Half-Used-Up Oil to Go Longer

[fredfactory]

How can you we help an oil make it to 15,000 miles?

Been looking at http://www.google.com.ar/patents/US6843916 and how systems like Fram High Mileage Oil Filter gel packs have been proposed and used, and what they were putting in the oil to extend distances to an oil change.

Can one mix Oil Extreme Concentrate (calcium sulfonate) which has a big 320 TBN, with STP Oil Treatment and a racing oil or LiquiMoly MOS2 or something to cover all the additive depletion? Trying to only add in enough, in small amounts, to boost the additive package in half used up oil.

Might want to do this if one is lazy, or to save money and the mess of an oil change, or has a fleet where you're just changing oil filters for 30,000 miles to save money.

With all the thought and money used on a bunch of additives, it might just be cheaper and easier to just change the oil ...

Best way is to change it!!!!

I'd just change the oil and be done with it.

If you want to count pennies get a Miti-Vac suck out half the oil thru the dipstick. Or drain some out of the oil pan via a Fumoto valve, and top up with fresh oil. A lot of work IMO.

If you want to really stretch things out get a dual remote filtration system and a few UOA's to establish how long you can safely go. It should be a heck of a lot longer than 15,000 miles, and no additives or partial drain and fills.

Lookin at UOAs, seems TBN drops, and I calculate just a 1/4 cup of the 320 TBN Oil Extreme would fix that. Too quick and easy.

Being efficient is important. If one bought a bottle of additive, making it last a couple of years spreads cost out. Use a partial bottle.

Does Lubrizol sell just raw additives in a soup, no base oil?

Lets assume a person wants to conserve on oil waste and changes.
Please no hostile people against conservation here.

No direct studies on just adding a half-quart worth of raw additives in every 5,000 miles that I've seen. Only a lot of patent and tech discussions about how motor oil breaks down additive compounds.

About filters, it does seem a better oil filter would be useful here for this goal.

How much oil does the engine consume? There is an argument that if the engine consumes enough oil to turn over in 15K miles you don't need to do anything other than change the filter every year or 2 to avoid carbon plugging.

Well the best way would be to run a quality oil, get a uoa at the end of your usual oil change interval. That can tell you how long you can go. As one member here Dnewton3 suggests, the many of us under utilize our oils capability.

That would be better than some unknown additive in an attempt to raise tbn. Tbn is not the end all be all.

With filters, a mobil 1 filter or a fram ultra is all the filter i need. Changing them too often is wasting the filtering ability as well. I feel filters will filter better as they are used, up to a point.

Another penny wise....

Buy an extended performance oil like Mobil 1 EP, Castrol EP, or Amsoil SS, use one of the 15,000 mile filters available, and forget the additives...Easy...

The Oil Extreme Concentrate raises TBN by 1.7 if you put 1 oz in a sump (1/6 of the bottle), and its just got calcium sulfonate. TBN is covered here. Can't find a VOA on Liqui Moly Motor Protect, thinking a partial bottle of that might cover everything else.

Combining all three of these makes sense. Drain off a quart every 10,000 miles or 1 year, and add back a new quart of one of the Extended Performance oils mentioned, and change the oil filter using the best oil filter around. Thats once a year.

I guess the other approach, just changing the filter every 6 months and adding in 4 oz of a magic additive package, is easier, maybe important for a fleet trying to go forever.

Quit being cheap and just change the oil it not hard to do

 

[fredfactory]

1 oz Oil Extreme Concentrate raises TBN by 1.7 (6 quart sump)
1 oz ZDDPlus Oil Additive raises zddp by 260 ppm
Would adding in 8 oz of a 0w50 with wide visc spread add enough VII back that has degraded? Maybe there is a concentrated form out there. Trying to keep the amount down. So far the TBN-ZDDP treatment is only 2 oz.

I've seen recycled oil on the shelves with a green cap. No idea how they do it.

Oil extreme is pretty awesome.. But I am positive it is priced high. Good to be thinking of conservation. Just don't hurt your own wallet too much or your own car to be an aggressive conservationist. But I do like the idea behind it. We only have this place has home. Better not make our planet a mess. That said.. I don't believe in global warming. For numerous reasons

but that's not what this is all about..

Gotta use only a little of it at a time to water down the cost. It has a ton of TBN over base in it. So 1 oz (1/6 of a bottle) is an adequate dose every 6 months or a year to bump up TBN.
Thats the approach I want to take here, just 1 oz at a time of anything, mix them all to no more than 5 oz, less than 1 cup every time something is added to boost the worn out additives.

 

[ThirdeYe]

Why not just use an oil that's rated to go that long, like Mobil 1 EP or Amsoil?

 

[fdcg27]

I'd be very careful about playing formulator in an effort to extend OCIs.
If the subject engine is one that you have little concern for, then by all means experiment.
Just bear in mind that you will be experimenting and that there aren't more than a few members here who can offer you any advice on this informed with any real knowledge.
If you seek to save money, deals on oil and oil filters abound and you could always go two OCIs on a quality filter. You could also simply run 10K on a synthetic oil, or even 15K if you feel a little daring, although this would be less daring than mixing various potions into an engine's oil without any good documentation to support the stuff you propose to use or much informed guidance on how to use it.
If you seek to save resources, just be sure and return the drained oil to a retailer who'll recycle it.
If you seek to try something different, then go ahead with your idea but bear in mind that you might end up with unanticipated bad results.

Looked around.
Here's a 5 oz total treatment, small amount that should do it:

1 oz Oil Extreme Concentrate raises TBN by 1.7 (6 quart sump)
1 oz ZDDPlus Oil Additive raises zddp by 260 ppm
3 oz Schaeffers #132 Moly E.P. Engine Oil Treatment

Every 6 months. With an oil filter change every 1 yr with premium oil filter, as suggested above.

Now I need to sample the oil once a year to check viscosity, maybe timing how long it takes to run out of a test tube at room temp compared to a new 5w30 sample.

TBN, anti wear, and moly-penetro-vi covered with the approach.
Using only partial bottles means it lasts.
