^^^ Agreed... For the first year of ownership I have been changing about every 3 months simply because there was no documented history on the vehicle and I would like to get it to a good point. Doing this has pointed out a few leaking spots (oil pan or rear main, valve cover, possible side rod inspection cover) so I will continue to do this for another oil change or two and then go based on my mileage and what I get back from BlackStone when I get around to sending in the information sample.

He says Zinc is a good thing... no debunk that I can see... just a marketing spin put on to justify what they sell.

Yeah, Jalopnik's headline is not accurate as usual. I think the takeaway is that that dude's opinion is that current ZDDP levels are fine except for break-in of flat tappet engines.
Plenty of reason to do it this way. Scientific fact for one thing, All conventional oil will begin to break down after being run in an engine, after 6 months oil will lose much of its lubricating properties from the chemical process that also breaks down additives.
If oil didn't break down, then there would be no reason to ever change it. All you would need to do was change the filter once every few years or so regardless of mileage. If your drive consists of nothing but stop and go driving and short trips like me, then you need to change your oil more frequently regardless of miles driven. The official toyota schedule for severe duty says oil should be changed every 6 months, even if you didn't drive very far, but no more than 5,000 miles between changes of oil and filter.
For those of you changing your oil only once a year...you're doing it wrong.

Please back this up with facts.. Not the fact that oil changes are necessary, but your statements of how often they are required.

Its not hard to look in your owners manual and prove that to yourself. Toyota recommends 6 months between oil changes (severe duty) regardless of miles driven.
http://hugh4prez.nate-online.com/Cruiser and M416 Manuals/1986 Maintenance.pdf
See page 7
You went from every 4 months no matter what, to 6 months as recommended by Toyota in 198something. Oil has changed a bit in the last 30 years..
Again, please show scientific (your own words) that oil left static for 4-6 months needs to be changed.
Show me the data that backs your information up.
Here, I'll start

I said 4 months no matter what? LOL you need to have your eyes checked. I never said any such thing at all. Toyota specifies 6 months, that much is already proven.
If you don't believe that conventional motor oil degrades over time in a 1930's tech engine with a carburetor, then far be it from me to try to prove otherwise, but I will give it a shot.

This test shows the oil was degrading after only 5 hours of use, significantly around the piston land area due to extremes there.
http://www.tytlabs.com/english/review/rev383epdf/e383_036moritani.pdf
This paper says that the oil has begun to degrade as soon as it begins to change colors
http://www.lubeng.com.au/assets/files/technitips/068_Motor Oil Degradation.pdf
http://www.upmpg.com/lubricationnews/why_motoroil_deteriorates/
Scientific fact that engine oil breaks down over time after you use it.
BTW, why so much rancor over my conservative approach to changing my engine oil more often than you do? Do you just hate to see people spend their own money? I also wax my vehicles 4 times a year too and change the antifreeze every 2 years.
Even if they don't need it.
Cruiserdrew
On the way there
It's cool, change as much as you like. It's still a trivial expense in the life of a Land Cruiser. Delo is good stuff.
I've adopted a different approach, that is easy to think about and remember. I change every 5000 miles on the 5000 miles on the odometer. So 150K, 155K etc. It's easy that way and I don't need a sticker to tell me it's time to change. It averages out to about once per year on the Cruiser fleet and twice per year on my wife's car.
As we have discussed before, it is more important to have a schedule, and stick to it, than exactly what the schedule is. If you are changing 3 times per year, you'll get good life from your motor. You feel good, your Cruiser is fine with it, everyone is happy. Others get nutty and get weekly oil analysis looking for non-existent problems and that's cool too. They are happy, Cruiser is happy.
So, 4 months, 6 months, yearly, all will work fine. No matter what, it won't last forever, but will likely last decades with few issues. Remember too, that if your truck uses any oil, and you check and replace, then you are continuously replacing the additives and can cut your change intervals a bit. But at 3x per year, with a good oil like Delo, you have one of the best maintained motors in the USA.

Yep, obviously my eyes need to be checked... Toyota recommends 6 months in harsh climates. It's not proven with modern oils. Just recommended with 30 year old oils...
Okay
Huh.. So many years depending on the oil huh...
Interesting....
Oddly enough that article has nothing on actually oil change intervals. It does recommend that you do not use oil that is over 3 years old tho..
huh.. 12 months...
psst.. 20,000 kilometers = About 12K miles... And again no discussion about time..
No, the oil at the lands was changing after 5 hours of use.
BTW, I love the end of the paper that states that figures 5, 7, 9, 10, and 11 were incorrect for a couple years Pure confidence there....
No, it says the oil is designed to change color so as to not damage the motor..
It also says there is not definite numbers to change the oil by..
Even Amsoil ( a great synthetic that you do not admit to using) maintains that they can go much longer than conventional dino oils.
Of COURSE it does. However, that does not mean that it is not protecting the engine properly. Tires wear the second they hit the pavement as well. You replace them every 300 miles?
It's simple. It's not needed. Telling people that it's a good idea to change your oil every 3K or 4 months is a good idea and they are "doing it wrong" if they change their oil yearly is silly. It's not an absolute. If you drive 75K a year, every 3 months may not be adequate. But it also may be fine because of the driving conditions.
Your best bet is to get your oil analyzed and see exactly how long your oil can go. If not, you are generally wasting oil and money. And I hate to see people wasting their own money...

Where do I say you have to change the oil every 4 months no matter what?
Where do I tell anyone that they should change their oil every 4 months?
Where do I say oil sitting static goes bad?
Toyota doesn't claim 6 months in harsh climates, it claims 6 months of harsh USE, which means dusty conditions, cold starts, stop and go traffic, lots of idling etc.
I would question your ability to read anything and come up with an accurate representation of the information you just consumed.
I do appreciate the fact that you are trying to save me the $70 a year extra I am spending changing my oil so much, but I will continue to do so even to your dismay.
Think of frequent oil changes likened to fire insurance, you pay extra to have it, probably won't ever need it, but the alternative of not having it could be costly.
Wow, that's alot of oil changing.

Ok I think that is enough of the back and forth on who's e-$%^ is bigger. Suffice it to say that people will determine, based on THEIR OWN METHODS, what is a proper OCI for their particular application. One OCI does not make it equal or greater than another as there are too many variables to consistently get the correct answer. Smartypants - I think that is what Mace is trying to get across. There are recommendations within the manual that were created for the time that the manual was done. HOWEVER, that does not necesssarily make them correct, think of them more as guidelines.
As I stated before, my father was an ademant man about changing oil in all the cars at 3k miles (and he only EVER used Pennzoil) and refused to pay someone money to do it (if he hurt his back guess who was under the car changing the oil
). Anyways, over the years that changed as the needs of the vehicles (as they became newer), our driving habits (they did a 60+ mile commute daily), and money really changed. Now with their new 2011 Honda Pilot he changes the oil (again he is now 70 and does it himself) on the recommended 7500 mile interval as stated by the manual (and believe it or not that big ole V6 only takes 4qts!!) or when he has time. We have gone from a society that relied on doing the analysis ourselves to relying on an idiot light that tells us when we need to change our own shorts.
And just to clarify - in your first post (Smartypants) you did state that you change the oil every 4 months regardless of mileage. Mace questioned this stating there is no reason to do this which is what lead to the above spiraling tyrade. You apparently have your set reasons as to why you do this and that is fine, I think Mace was just trying to state (since you have a very low number of posts and I personally have not seen an introduction stating what your mechanical/vehicle background is) this was not necessary to try and help a new member out (which is what this forum is all about!!).
Anyways, back to who uses what! I received a $25 Walmart gift card from my chief for my bday however I refuse to go into a Wallshart (personal reasons that I can explain if needed) but don't want to give it back to her. Thinking of going and grabbing a pint of MMO to add to my next oil change but really have an ethical issue with this as I have not been into one in over 7yrs. Decisions decisions.

Good post. But one clarification. Just like modifications, I really do not care what people do to their own truck. If a person honestly believes in doing something a certain way, they are going to do it anyway. The guy that removed the front inner axle seals so that his bearings could be lubed by gear oil comes to mind. Land Cruisers are what their owners want them to be. The problem is when someone that may not have much background knowledge hops on the computer and reads this thread on which oil to use in his truck. He sees a post by some guy stating strongly that he changes his oil every 4 months no matter what, and takes that at face value. So he does it as well. And wastes his own money.
You obviously CARE A WHOLE LOT. Otherwise you wouldn't have spent HOURS UPON HOURS trying everything in the book to make me look foolish, you even went so far as to use a quote from an entirely different and unrelated thread to try and keep your ego happy.But one clarification. Just like modifications, I really do not care what people do to their own truck.
Your trying to save me a buck by telling me to get oil analysis, which costs more than the oil change and does nothing to help the oil. I will save the money from not following your advice and just be ensured that my oil is in tip top shape at all times.
You shouldn't assume that low post count= someone with little knowledge or skill, just as i assume a high post count is not always a reflection of skill, but could just be ego inflating behavior and not in a true spirit of helping others.
Oil breaks down over time, undisputed fact.
Also Toyota's 6 months between oil changes wasn't just a "recommendation" if you didn't do it you voided your warranty. So if they recommend you change it every 6 months regardless of mileage, then I would think that would suffice.
Oil changes are cheap and quick and easy to accomplish, oil disposal isn't a problem. What's the big deal?
Gonna go change my oil now, have a nice wonderful, fun filled, and adventure packed day.
