My Toyota Sienna does not need an elaborate break-in. But following a few simple tips for the first 1600 km (1000 miles) can add to the future economy and long life of my vehicle:
Do not drive over 88 km/h (55 mph). Run the engine at moderate speed between 2000 and 4000 rpm. Avoid full-throttle starts. Try to avoid hard stops during the first 300 km (200 miles). Do not drive for a long time at any single speed, either fast or slow. Do not tow a trailer during the first 800 km (500 miles).
My Toyota Sienna Fuel FUEL TYPE
my new Toyota Sienna must use only unleaded gasoline.
To help prevent gas station mix-ups, my Toyota Sienna has a new smaller fuel tank opening. The special nozzle on pumps with unleaded fuel will fit it, but the larger standard nozzle on pumps with leaded gas will not.
At a minimum, the gasoline you use should meet the specifications of ASTM D4814 in the U.S.A. and CGSB 3.5-M93 in Canada.
NOTICE
Do not use leaded gasoline. Use of leaded gasoline will cause the Toyota Sienna three-way catalytic converter to lose its effectiveness and the emission control system to function improperly. Also, this can increase maintenance costs.
Toyota Sienna OCTANE RATING
Select Octane Rating 87 (Research Octane Number 91) or higher. For improved vehicle performance, the use of premium unleaded gasoline with an Octane Rating of 91 (Research Octane Number 96) or higher is recommended.
Use of unleaded gasoline with an octane rating or research octane number lower than stated above will cause persistent heavy knocking. If it is severe, this will lead to engine damage.
If My Toyota Sienna engine knocks...
If I detect heavy knocking even when using the recommended fuel, or if I hear steady knocking Toyota Sienna Toyota dealer.
However, now and then, you may notice light knocking for a short time while accelerating or driving up hills. This is no need of concern.
GASOLINES CONTAINING DETERGENT ADDITIVES
recommend use of gasolines that contain detergent additives to avoid build-up of engine deposits.
For further details, ask your Toyota dealer or a local gasoline retailer.
IMPROVED GASOLINES
The American Automobile Manufacturers Association (AAMA) has developed a specification of improved gasolines. The AAMA specification offers optimal fuel information for better vehicle performance and better protection of your engine.
recommend the use of gasolines that meet the AAMA specification, if available, for improved driveability and emission control system.
GASOLINES CONTAINING MTBE
Gasolines that contain MTBE (Methyl Tertiary-Butyl Ether) are available in the market. If you use a gasoline mixed with MTBE, make certain that it does not contain more than 15% of MTBE.
GASOLINES CONTAINING MMT
Some gasolines contain an octane-en-hancing additive called MMT (methylcyclopentadienyl manganese tricarbonyl).
do not recommend the use of gasolines that contain MMT. If fuels containing MMT are used, your emission control system may be adversely affected. The Malfunction Indicator Lamp on the instrument cluster may come on. If this happens, contact your Toyota Sienna dealer for service.
GASOLINES CONTAINING ALCOHOL
If you use gasohol in your Toyota Sienna, be sure that it is unleaded, has an octane rating no lower than 87 and does not contain more than 10% ethanol.
Gasohol is a mixture of gasoline and ethanol.
doe not recommend the use of gasolines containing methanol. If you use gasoline containing methanol, use only gasoline meeting the requirements above and also containing less than 5% methanol with cosolvents and corrosion inhibitors for methanol.
Toyota Sienna GASOLINES QUALITY
In a very few cases, you may experience driveability problems caused by the particular gasoline that you are using. If you continue to have unacceptable driveability, try changing gasoline brands. If that does not rectify your problem, then consult your Toyota dealer.
NOTICE
Do not use gasohol other than stated above. It will cause Toyota Sienna fuel system damage or Toyota Sienna performance problems.
If driveability problems occur (poor hot starting, vaporizing, engine knock, etc.), discontinue the use.
Take care not to spill gasohol during refueling. Gasohol may cause paint damage.

Operation in foreign countries Three-way catalytic converter
If you plan to drive your Toyota in
another country... First, comply with the vehicle registration laws.
Second, confirm the availability of the correct fuel (unleaded and minimum octane number).
The three-way catalytic converter is an emission control device installed in the exhaust system. The purpose is to reduce pollutants in the exhaust gas.
A large amount of unburned gases flowing into the three-way catalytic converter may cause it to overheat and create a fire hazard. To prevent this and other damage, observe the following precautions: Use only unleaded gasoline.
Type B
Toyota Sienna Engine exhaust cautions
Do not drive with an extremely low fuel level; running out of fuel could cause the engine to misfire, creating an excessive load on the three-way catalytic converter.
Do not allow the Toyota Sienna engine to run at idle speed for more than 20 minutes.
Avoid racing the Toyota Sienna engine.
Do not push-start or pull-start your Toyota Sienna.
Do not turn off the ignition while the vehicle is moving.
Keep your engine in good running order. Malfunctions in the engine electrical system, electronic ignition system/distributor ignition system or fuel system could cause an extremely high three-way catalytic converter temperature.
If the engine becomes difficult to start or stalls frequently, take your vehicle in for a check-up as soon as possible. Remember, my Toyota dealer knows your Toyota Sienna and its three-way catalytic converter system best.
So this article states that a 2011 Seinna can run 87, or 91 or higher octane for higher performance...Does this mean that 87 gives low performance? Exactly what IS low performance in a Sienna??..and exactly what IS high performance in a Sienna engine?? ALSO...I want to run the octane which is best for my engine physically for the long run. Will running 87..the poor performance octane affect engine longevity years down the line?? Will 91 octane or higher--for high performance INCREASE engine longevity? These three octane numbers are confusing to the average consumer. Because how can a 91 octane engine run all three and it doesn't matter to the longevity of the engine? Why doesn't Toyota just tell you to use what give best performance and best longevity of the engine? It all seems like a Toyota smoke screen by lying to the consumer telling them that the Sienna runs on regular octane...when in fact they should have high test 91 or higher! I do want my Sienna to run perfect of course, but by the same token I don't wish to throw away money for nothing. SOOOO once again I ask..WHICH OCTANE 87, 91, OR HIGHER IS BEST FOR THE LONGEVITY OF THE 2011 SIENNA V6 ENGINE?
