Does Toyota have any requirements for oil weight?
What are the + and - of 0W compared to 5W or 10W?
0W flows better cold, so better fuel economy during warm up. Any downsides? Will 0W have more wear in a cold engine?
To use 2000 series cost a bit more.
I found Toyota's API Requirement here. Their response does not directly address oil viscosity....
Thank you for contacting Toyota Motor Sales, U.S.A., Inc.
We appreciate your inquiry regarding the us of synthetic oil in your 4Runner.
All Toyota vehicles come from the factory with natural petroleum-based engine oil. Toyota is currently recommending American Petroleum Institute (API) grade SJ petroleum-based engine oil. In moderate climates, this oil should have a Society of Automotive Engineers (SAE) viscosity rating of 5W-30. In our high mileage tests with preventative maintenance performed at the recommended intervals, the recommended natural petroleum-based oil has provided excellent service.
If you decide to use synthetic oil for the engine, it would be best not to switch until the first scheduled oil change. Synthetic oil should meet or exceed the above specifications. Even if synthetic oil is used, we do not recommend a longer oil change interval. Also, once synthetic oil is used, you should keep using it and not switch back and forth with natural petroleum-based oil.
If the engine oil that you use, whether natural or synthetic, does not meet the above specifications or is defective, any resulting damage to the engine will not be covered by the Toyota New Vehicle Limited Warranty. You can protect yourself against this possibility by having your maintenance services performed by a factory-authorized Toyota dealer.
The Scheduled Maintenance Guide cites the minimum recommended services under what is assumed to be a standard, or typical set of driving conditions. In terms of maintaining the integrity of your warranty, our recommendation is adherence to the Scheduled Maintenance guide, which recommends service intervals of every 5000 miles, or 6 months, whichever comes first.
According to our records, the 4Runner we have on file for your is V8 4.7 4WD . The oil capacity for that engine, with a filter, is 6.5 quarts.
Your email has been documented at our National Headquarters under file #200412021090. If we can be of further assistance, please feel free to contact us.

Just to set the record straight.
Congress in 1975 enacted the federal Magnuson-Moss Act to regulate written consumer product warranties. An examination of the law reveals warranties remain intact when Amsoil Synthetic Lubricants are used.
The law was meant to give consumers detailed information about warranty coverage before they buy.
Congress charged the Federal Trade Commission with creation of the specifics of the law.
The FTC set down three rules under the Act: the Disclosure Rule, the Pre-Sale Availability Rule and the Dispute Resolution Rule.
Those rules require warrantors to title their written warranty as either full or limited, provide a single, clear and easy-to-read document that spells out certain information about coverage and ensure that warranties are available where the products are sold so that consumers can read them before buying.
In passing the Act, Congress meant to give consumers access to warranty information, let consumers comparison shop for warranties, encourage warranty competition and promote timely and complete performance of warranty obligations.
While the Magnuson-Moss Act does not require manufacturers to provide a written warranty, it provides specific rules when one is provided. Among those provisions, FTC regulations state: (c) No warrantor of a consumer product may condition his written or implied warranty of such product on the consumers using, in connection with such product, any article or service (other than article or service provided without charge under the terms of the warranty) which is identified by brand, trade, or corporate name; except that the prohibition of this subsection may be waived by the Commission if ((1)the warrantor satisfies the Commission that the warranted product will function properly only if the article or service so identified is used in connection with the warranted product, and (2) the Commission finds that such a waiver is in the public interest. ((42 U.S.C.2302(C))
That means your warranty stands when you use Amsoil Synthetic Lubricants.
Vehicle manufacturers recommend lubricants according to their viscosity grade and service classification. Any oil, whether it s conventional petroleum motor oil or synthetic, meeting the correct viscosity grade,5W-30 for example, and the current API SL and ILSAC GF-3 North American service classifications may be used without affecting warranty coverage. AMSOIL motor oils are recommended for use in applications requiring these specifications.
Furthermore, the practice of extending oil drain intervals does not void warranties. Original equipment manufacturers pay or deny warranty claims based on the findings of failure analysis. To affect the vehicle warranty, the lubricant must be directly responsible for the failure. If the oil didn't cause the problem the warranty cannot be voided, regardless of brand or length of time in use.
Many original equipment manufacturers would like you to believe you can only use their products. However, it s a violation of the consumer protections set forth in the Magnuson-Moss Act, unless they re willing to provide you those products free of charge.
Amsoil offers a warranty that covers the cost of repair or replacement of a proven mechanically sound engine damaged as a result of using Amsoil synthetic motor oil. However, it has never happened. Thirty years of experience proves Amsoil can be installed in any vehicle with complete confidence.
Amsoil further backs its products with action when a customer reports being told their warranty is voided if they use synthetics.
If you have heard from any member of a business that the use of Amsoil Motor Oil or the practice of extending drain intervals will void warranties, send Amsoil all the details including the name of the business, business owner or manager and the individual making the claims, in a signed and dated letter. Send the letter to the Technical Services Department at corporate headquarters and an Amsoil representative will send them a letter explaining the facts.

The system can't be seen. The front plate conceals it, but to change them you can just reach behind the bumper. This location is perfect and looks stock; even the hoses match the trans cooler hoses. I used steel for the mounting plate because I had it lying around. I would have used aluminum or stainless if I had some. Just make sure the thickness is at least 3/16".

Re: Anything new to report?
Just make the mounting plate up (3"x 7.5"x 3/16") prior to installing. You will need a right angle drill, 7/8" crow's foot (to tighten the hose ends at the filter block), and stainless rivets. The pictures and write-up should help. If you have any questions feel free to contact me. I check this site daily (weekdays).

14 years later how is/ did the system doing/do
Koz I'm a newbie, just purchased a 2006 Ltd with the 4.7. 128,000 miles.
I've been reading alot about different oils (engine,trans, diffs etc.)
I'm impressed with what I've read on Amsoil products. How has the flow/ bypass system held up. What was the highest mileage you got before having to change out the oil?

I removed the bypass system at about 300,000 miles because of the proof of filtration by the Amsoil EAO oil filters being so good. Comparing the hard to find filter dimensions chart I found a larger oil filter that fit.
If you have access to the Amsoil EAO oil filters, the bypass isn't needed.
