1st oil change at 5k or 10k?

Sounds like a Plan

 

Hmm. Why not do it yourself at 5K and then have dealers do it at 10K which is the recommended?

 

Just took my 2010 in for the 5K oil change I have the maint program and they replaced the oil filter, rotated the tires and added 1 quart of syn oil. Said they will adjust and pro-rate my maint contract to adjust the new 10K oil change interval. At 10K they will replace all the oil.

Well not sure if thats standard practice but no dealer I know off just change the oil filter and top up the oil.

Maybe it is something they do in the US.

 

Not Really...That's a new one

 

I agree. I changed the factory fill oil at 2100 miles, and just changed again at 5100 miles, using Toyota 0W-20 oil because of the Toyota oil's unusually high molybdenum and viscosity index compared to most other 0W-20 oils. I will now be changing at the specified 10,000 mile internal so the next change is at about 15,000 miles.

Rumple

 

I love oil threads, shouldn't there be at least 1 person to not fear the reaper and actually let the 1st oil change go to 10,000mi? Perhaps you have heard of a manufacturer named Toyota? They are quite big on this planet called earth. Since Toyota did design, manufacture and services these cars for a living, shouldn't we have some trust in them? If Toyota gives a 1 year or 10,000mi interval for the 1st oil change, then rest assured you are fine to let it go until then. If you change the oil earlier to make it more convenient for you then so be it.

 

jcgee88,

Clearly you either did not read the posts that began my exchange with Octavia, or you simply failed to comprehend what was said.

I said TWO things, First that IF you lease a car, then you should leave the contaminated oil in the engine, because you gain nothing by paying to change it more often than the bare minimum.

Then I explained what I do, because I keep my cars.

I explain this to inform all who take the 10,000 mile oil change for their 25 to 40,000 Dollar 'Investment' in a new Prius, that doing the minimum matters ONLY if you care about the car NOT AT ALL. As is often the case of people who lease cars. I would say that is ALWAYS the case with those I have known who lease their cars.

I take excellent care of my cars because I usually keep them, or sell them to a clsoe relative who will keep them. So you were "preaching":glare: to the choir.

 

Toyota also sold a lot of cars that ended up getting their engines rebuilt from sludge accumulation, and people followed the Toyota minimum requirements then as well. So much for "Trust" in some profit making self serving corporation.

FYI . . . New engines wear a lot at first, like for the first 5000 miles. They do this because metal upon metal friction causes the metals to wear, and that creates metal particles, 'wear particles' the larger of them get trapped by the oil filter, the smaller particles circulate with the oil. The longer you delay the task of drain and refill the motor oil, the more contaminated the oil becomes from build up of wear particles, dirt, condensation. In the first 5000 miles the wear particles are produced at a rate equal to all the wear particles generated over the next 50,000 miles. Leaving them in the engine is good for the people who want to sell new cars more often. The Toyota company would be counted among such companys. I purchase only new cars. Mainly I wish to avoid buying a car owned by someone with your attitude toward car maintenance. It has served me well. I therefore highly recommend it, and avoid buying Used cars that had originally been rented for a few years by someone interested in only using, and then disgarding the vehicle.

 

HAHAHAHAHA Trust them? You kidding right?

Never trust your dearler.

 

The 2010 Prius come with synthetic oil form the factory, to judge it by other, older Toyota models is not realistic. Modern manufacturing results in far less break in wear than was the case years ago, so oil change intervals are not as short as they were. Damage to engines results from people who never change their oil, not those that follow factory intervals.

 

I trust my dealer only half the distance that I can throw him. I change my own oil and maintain records of all maintenance.

 

Don't prematurely pat yourself on the back just yet...let's wait to see who's still standing (namely, the middle class) at the end of his term, shall we?

Also, do you have the wherewithal to not infuse threads in this forum with politics? Yes, I know you were responding to Octavia but I think you're both missing the fact that the real world simply can't entertain an ideologue's vision of utopia (as you have so eloquently and hypocritically proven with your blatant suggestion here that lease holders intentionally contribute to the the misfortune of a potential future owner by being reckless and irresponsible with the vehicle...because by damn, we're gonna' show that evil corporation who's the boss!).

 

First Toyota will not cover a repair if i go beyond 10k on oil. But they provide a full warranty for 10k oil changes.

Toyota says 10k i belive they know more about their motors than i do. I still see so many people saying they do the 3k oil change because "it's what they always done" and I know their just wasting their time and money. Why don't we all just change our oil every 1,000 miles then our cars will last millions of miles?

when GM cars get 5-12k out of regular oil i know a prius can go 10k on synthetic oil. And before you start to bash gm i have seen many of them get well over 200,000 miles with no engine wear doing the long oil changes.

Everyone can do what makes them happy. I also would like to see a someone send in their used oil at 10k and for the test to come back and say the oil was past it use and was causeing major damage to the motor. Every one i have seen said they could go longer with no harm to the engine.

 

I changed the oil every 5kmi. on our 99 Chevy Venture. It had 230,000mi on it when we sold it 2 years ago and nothing ever went wrong with the engine,except the dreaded LIM gasket, and I still see it running around town today.

 

Not only that, the Prius ICE isn't on 100% of the time and it's spun up to 1000 rpm by MG1 before injecting fuel, thereby minimizing the wear and tear and condensation of the stop/start cycles.

 

Well said...and here is some detail on how...

In the "old days," various engine parts were cast or machined,
and Q/A was done by testing some small percentage of the
finished product. In the case of large components that were
machined, for example, the engine block, as the grinding bits
got worn down, the machined results would start to drift.

Such drift caused two undesirable results:

1. Greater variability on the finished product, i.e., some
cars came off the line and they were forever lemons.
2. Mechanical engineers who designed the product had
to account for the drift by making tolerances looser
rather than tighter. Looser tolerances mean you
can't run "close to the edge," i.e., more efficiently.

In today's manufacturing process, every major part is
measured to a high degree of precision using a
"Coordinate Measuring Machine" (CMM). As a drill bit
starts to dull, the CMM will detect the drift before it
reaches an impactful stage, and notify the operator
to replace the bit. This also means that the end
result is not beholden to the skill/experience of the
machine operator.

Starting in the late-90s, automotive manufacturers
integrated CMM's into the middle of their manufacturing
lines, to replace the strategy of "test a few at the
end of the line." This proved so successful in
improving quality that automotive manufacturers
are now the world's largest consumers of CMMs.

How do I know this? Because I worked for a company
that provided the computers for the CMMs, for the
company that is the world's largest manufacturer
of CMMs. And, when you walked down the assembly
line of this CMM company, at least half of their CMMs
had automotive company names listed as the customer.

 

New Yorker, if you are saying you take good
care of your cars and you recommend others
do so, too, then we are on the same page. This
obviously covers the cars you own or plan to
sell to close relatives.

My post was in response to the first part of
your original post, which covered leased cars.
I don't see how I could fail to understand your
meaning, since you were quite clear:

>If you Leased the Prius and will be turning it over
>to somebody else, keep the contaminated oil in
>the engine as long as possible, it won't matter to
>you, and it saves you $ $ $ !

I would give you the benefit of the doubt that your
phrase "as long as possible" may correspond to
the maximum recommended oil change interval,
what you also call the "bare minimum." In that
case, I have no disagreement with that.

But, if you really meant "as long as possible" in
the sense of beyond Toyota's recommendation,
that's where we would disagree. Your original
post could be easily construed that way.

Lastly, I have been driving leased cars for the
last twelve years, and my own practice was to
follow the manufacturer's recommended oil
change intervals. I would do the oil change
at the recommended time even if I only had a
month to go on the lease. Again, this was to
ensure maximum reliablity of the car while it
was in my possession.

 

Engine technology advances but metal to metal surfaces still exist, still 'wear-in', and still produce vastly more "wear Particles" as they do. Engines are worn, aka slightly damaged, by normal use. That is why they eventually wear out. The trick is in slowing that so they run well, retain their power, and don't waste oil and gas. Oil changes when the engine is wearing in helps in that effort. Keeping the contaminated oil in the engine as long as you can does not.
