Blush!
It was time to change the oil in my Mexican 2009 Sienna, this week. I referred to this issue in an earlier thread. It is not like the 2002 was. No filter can. A filter case assembly under the car, and can’t access it without raising car. I scrounged up the correct tool, I think from Rock Auto. I bought heavy duty ramps and two jack stands, the type with the U-bolt.
I had a five quart container of Mobil-1 EP, 10W-30, plus one quart.
When it was time to do the deed, I ran the car up on the ramps, made sure it was properly lined up. I put the jack stands under, but they are the type with the U-bolts, so I could not make a perfect contact. I noted in the jack stand manual the warranty is not valid in Mexico. Sigh!
I took the 3/8 driver which is supposed to take out the drain cap so you can drain the oil without making a mess. Ha! With all my force on the 3/8 handle, it would not come out. I had to take off the whole assembly. It still took all my force to break it loose. Stated spec is, I think, 15 - 23 ft. lbs. Grrrr!!! I wonder if they used a heavy duty impact driver to put that thing on. So, I had oil all around the assembly.
I put the filter assembly back on and drained the oil from the oil pan. There was the previous washer on the drain plug, looked like some plastic substance. I had two of the same nylon washers I used for nearly 200,000 miles on the 2002 and put one on, and tightened it by experience.
I added the five quarts of oil, and checked the dipstick. There was more than one dipstick present!!! One was made of metal; the other one was human, sort of. There was no oil on the dipstick, I mean the metal one, the other one had a bit on him. Then, and only then did I dig out the manual. You did know Real Men don’t read manuals, didn’t you? 
The manual said the motor takes 6.4 quarts with new filter. Oops!
I only had one more quart, so I put it in. Knowing half a quart low is not a disaster if the motor is not pressed, I chose not to add a half quart of dino oil until I can get another quart of the same oil. Now that I know, next trip to the States I will buy a number of 5 quart jugs of Mobil-1 EP. They are twice the price in Mexico, over sixty dollars, if you can find them, and I will use empty quart dino oil bottles to break down that 1.4 quarts the motor needs during refill.
I also learned that the manual does include 20W-50 as a choice, though 5W-30 is shown as preferred. I am guessing they know the Mexicans all use 20W-50 so to avoid alienating customers include it in the oil choices. I am also guessing that listing in the manual frees the customer from warranty violations for using the heavier oil.
When I finished, I gave the 6+ quarts of used oil to a cousin. He said he can use it for coating boards when he pours cement, but may use it in his Stihl chain saw for the chain lube system. He never had a chain saw until I took one and he borrowed it a few times. I also taught him how to fix minor problems, such as clogged exhaust screen and fouled plug and weak gas mixture from excess storage time. Oh, and how to sharpen the chain, which he instantly was better at doing once shown the concepts. He is a clever man.
A further note here. When I was done, I tried to take off the special filter assembly tool. It would not come off. Concerned that it would fall off when driving and bounce through the windshield if a Mercedes Benz and kill the mistress of a government official, [/sarcasm] I spent a lot of time trying to get that special tool back off. I even got a claw hammer under there. I finally realized it is probably not going to fall off and just left it. I theorize that the force it took to get it off crimped the aluminum tool over the assembly and bound it in place. I have no idea how to get it off if a hammer and a screwdriver and a claw hammer won’t take it off.
Well, the only idea I had was to buy a new filter assembly cap and a new special tool from Rock Auto and make sure no one uses a high speed impact tool on it.
