Oil Change... 0w20? wtf?

Good ol' broscience. Not a shred of evidence to support a claim, but damn it, they know better than the engineers. Reminds me of the BMW forums talking about how BMW doesn't know how to build a motor or what kind of oil they should use.

Can we talk about cast iron shavings that occur in oil from all aluminum blocks now? lol.

Sounds like something else I know...:D

So I picked up my new '12 LE on Wednesday but I noticed the dealer put a sticker on the windshield saying my next oil change is at 5K. I thought the first one was as 10K. (I have not read the whole manual yet so I'm not 100% sure)

aluminum block engines wear and create particles just like a solid cast iron block does, so calling that out as "broscience" would be a ridiculous argumentative postition indeed. The 1GR-FE does have "cast iron" sleeves in-case you were unaware...
 
Oil Viscosity

I agree with the people who support using 0-W20. Do you think Toyota would risk hundreds of millions of dollars replacing engines if it were not the correct oil, plus the absolute ruin of their reputation if the engines did fail due to incorrect viscosity. Besides, I have been using synthetic oil since around 1980 or 81 (Amsoil). I used it in a BMW back in those days with the recommended viscosity at the time. It is not something new on the block.
 
A question for any Canuck 4Runner owners?
What oil does your Canadian manual recommend?
I've read on the forum it says 0w-20 or 5w20 and they are in a colder climate then us.

I ran Mobil 1 5w-20 last summer and have Toyota 0w-20 in now.

Also a doozy straight from the manual.Read the last sentence. High speeds? I don't see how they could ever deny the warranty because of using the wrong oil with a statement like that in the owners manual.
Just tell them your always late to work and have to travel at high speeds so you put in 50w........per the manual.lol

so what about us people in hot climates like Las Vegas? I rarely get's below freezing here at all and most of the time it's in the 80's + I still think 0W20 is a little thin for a hot climate like ours?

I understand your trepidation. A "cold start" does not mean 20 degrees F outside. It means your engine, before it is started, is not circulating any oil. When you start it, the temperature of the oil waiting to be pumped is colder than it will be after the engine is started and oil is circulating. You will be fine in Vegas with 0W-20. If it gets hot enough in Vegas for that spec not to be effective you have other problems. Re-read the thread. There is some good info in it. Just look at Harper's chart above and the temperature range. I will say again: There is no place in North America where 0W-20 synthetic is not effective as an engine oil.

0w-20 would be fine but if you are uncomfortable with it you could use the 0w-30. I personally only use 0w-30 because I'm pretty much WOT every time I use the vehicle and I tow also.

Not a Canuck, and not from the Canadian Manual, but the attached page from a large 2010 4Runner document has what you're looking for. I think you'll find that the USA oil spec is for CAFE appearances and nothing else.

My manual and dealer recommend 0w20, I suppose that could change the further north you go in Canada, but here in the banana belt that's what they do.

Oil changes are at 5k when YOU pay, 10k when they pay.
 
1/2assed Cost–benefit analysis.

Toyota has made a decision that the benefits of the 0W20 outweigh the costs.
----------------------
What's the average life span of a modern car?
What is the usual cause of death?
Oil related engine failure?
Transmission failure?
Rust?
Accident?
----------------------
• fuel efficiency
• power
• longevity
• low maintenance and related costs
• low mfg costs
What are the goals of an engine owner/operator?
What are the goals of an engine designer?
Are the goals the same?
Is 0W20 the best oil to achieve those goals?

Is it worth the time, energy, and expense to research a better oil than the recommended?

Not today:)
