I just remember the take home message was not to waste your money on synthetic. I don't know about sludge buildup etc.
they did more than a 25k test, it was more like something closer to 100k, and found
no difference between reg oil and syn.. sludge will not build up if you change your oil
frequently, no matter what you use,.. like i said syn is really for race cars, the only advantage
i see that it gives our cars, is it flows better in extremely cold tempatures, and oh yeah,, (piece of mind)

All you have to do it change your oil in a reasonable amount of time
and buy a JAPANese car!

Like I said, toyotas aren't free from the laws of physics...there are a lot of other manufacturers that make quality powerplants. I'm not saying they aren't good...I just don't believe they are superior.

cool, musta seen you on 3.8mustang.com. anyways, on topic...i figure the cost of using reg oil is about half the price of using synthetic. but you can go about twice as long with the synthetic as you can with regular. so for me, it almost balances out.

The thing is, there are a lot of ppl out there that believe, no matter what kind of
oil it is, no matter how good it is, it should be changed after about 3-4k miles, because even
the best syn oil gets conaminated.. I also believe that, and i don't need an
oil analysis done to tell me what I already see with my own two eyes..(the oil turning black and
getting thicker), which by the way, happens to syn oils after 3-4k miles, I used to use
syn oils and do my own oils changes, so i know this first hand.. i stopped using
syn oils in about 1992, when i realized what i mentioned above...I Think the first time
i used them was in 1989, all i remember being out was "mobil1"..

This kind of misinformation is why people in North America still waste an obscene amount of natural resources by changing their oil when there's nothing wrong with it. This debate it endless, so I'm not going to waste too much of my breath, but you can't judge an oil's condition with your eyes: period. End of sentence.
There were issues with synthetics way back when they were first released. There are no longer such issues. I run my synthetic oil 5000 plus miles in my car. It has over 50k miles on it now. Oil analysis confirms that there are no abnormal wear particulates, and that the TBN (look it up if you don't know what it is) is still high... meaning even after 5000 miles, there is plenty of life left in the oil. Unless you're Clark Kent, I tend to doubt you can see those things. Oil turns darker as it gets older... it's supposed to. That dark color is carbon buildup, and it means the oil is doing its job and keep the motor clean.
I can understand if you're a bit hesitant after some bad experiences a few decades ago, but things have progressed substantially... time to enter the new millinium.

By the way, if you're interested in FACTUAL (i.e. oil analysis) information about all kinds of oils in all kinds of cars, check out:

3k-4k is a thing of the past with modern cars and modern oils unless of course you have money to burn

Beyond the warranty period, I'd agree. Oil analysis is inexpensive, and a great way to arrive at a change interval that is appropriate for your engine. The color of used engine oil has no bearing on its ability to lubricate.

You''re both right, it's been 15 yrs. and ive been using regular oil,
and have never had ANY engine problems of any kind on any of my cars
Thank you both for making my point even more clear
Also, you talk about wasting precious oil, meanwhile when you spend
double the money on syn oil, you just give the oil companies more money
to put right back into their oil plants, so they can produce even more oil, so
don't even try going that route, it all equals out..The only person that can give
lectures on not spending too much oil is someone that has an electric car
and have never had ANY engine problems of any kind on any of my cars

I've seen many oil analyses that had identical results at 6K miles as it did at 3K miles.

Here in Canada, when I owned my BMW (2001-2006) the car came with syn. and the interval was 25000 KM!! Believe it or not you would have to pay for it yourself if you wanted it done sooner. BMW's warranty would only cover the cost if you followed their 25000 interval!!
