Oil change mistake! Change or not?

Just keep track of the gas mileage, oil pressure, water temperature, and perceived "get up and go" to see if the 20w50 makes any difference compared to the recommended oil.
In the current warmer weather, it won't hurt a thing.
The recomended oil is actually thicker at start on a really cold morning than is a twenny fiddy in warm weather.
I don't think the heavier oil will do anything other than make the engine smoother and quieter.

Will he remember to change it in the fall regardless of mileage?
In the Sahara Desert maybe.
I would dump the thick oil and add the required viscosity oil.
250W-50 is too thick. If it were 10w30 or 10W-40 I would say keep it, not with 20W-50.

The effect of wrong oil is accumulative and slow.
If he is using the truck with too many cold starts and short trips then he ought to change the oil to correct weight and use it as an add on later or mower etc.
MA summers are not like FL so if he decides to keep it in I would tell him avoid revving up the engine in addition to avoiding too many cold starts if possible.
He can also drive the truch for 500 miles and dump the oil serves as cleaning agent.

Temperature limitations applied. 20W50 was good from 20 degrees on up. 10W30 and 10W40 was good from 0 degrees on up. Straight 10 weight was good up to 60 degrees. Straight 30 weight was good above 40 degrees. The preferred viscosity was 10W30.
I really wish they still did this.
If you can get access to an FSM,it`ll have all of the usable oil weights per Toyota,and not the EPA/CAFE/government.

Just curious, do you think that maybe Toyota or other manufactures might use different oil sump pumps in the same size engines in different countries due to different climates and common oil availability. This could possibly account for the differences in Toyota's oil recommendations between the US and Australia.

The real question is did you smack your brother upside the head? Since my wifes van takes a different weight than my car I literally check every quart before I pour it in. And then I check it again.
I would drain it after 500 miles as suggested before for 2 reasons:
1. You just flushed the engine
2. You have 5 years worth of lawnmower oil

Look up the phone number for a Toyota dealer in Austalia and call them up(use Skype) and ask the service department if that engine can handle the oil.
While you got them on the horn ask them what weight they use at the dealer for that engine.

I find it funny that someone would be worried enough to make a post about this but too cheap to spend 20 bucks to install the correct oil for there climate in a 2007 truck , MA is not Australia
To me its a nobrainer, at least put something close to the
proper viscosity (for your climate and use) back in the truck.
If the truck called for 20w50 and you accidently put 5w30 in it what would you do?

Probably wont make any difference. Just a 1or2 MPG difference. Plus it may get rid of the infamous Taco Tick, Tick, Tick on the 4L V-6.
UPDATE: I went over his house last night and he says the truck runs better then it ever did?? So I said take me for a quick ride "I wanted to see and hear for myself" And he is right no noise at start up motor is quiet even quieter then it was before and it's not sluggish when you push the gas. He will check the fuel economy for me and give me an update. So I said heck it looks like you made the right call leaving the 20w-50 synthetic in??

The 20w-50 will not blow any gaskets out, cause any wear on "tighter clearance or tolerances newer engines" so just leave it in as it's summer time it will not hurt anything. Clearances (the distance between parts, bearings etc) have not change in many many years. Tolerance the measurement given to manufactures that a part can go outside of the specified given number on the blueprint ( +.15 or -.15) and still be acceptable has zero affect from oil grade.

You can go up but you cant go down, he would have to take it out. This fear of heavier oils in warmer seasons show a complete lack of understanding of engines and lubricants. I am surpirsed and embarrassed. This is an Oil Board for Pete's sake! You guys better spend MORE time worrying about the unbiquitous 5w30 shearing out of grade - THAT will void your warranty.

Crinkles you're the best!
We've got operatives all around the world and sooner or later we'll get to the bottom of this.
Now can you get a hold of a manual for a Ford 4.6 Modular and tell me what's possible?

LOL
See it is Kuwait, not Massachusetts.

I wouldn't change it. It's a full synthetic with a pour point of -36F; so we're talking a far cry from a conventional 20W-50. I've seen a few on this board say they've either known someone, or that they themselves have in the past been, using Mobil1 15W-50 in cars that called thinner oils year round--with no ill effects--year after year...

I do not think Toyota does that, Whimsey.I do not think oil recommendations are related to the differences in mechanics but climates/operating conditions.
Most probably the engine will still be OK after 5K miles with this oil but why risk it? It is 30 dollars to buy M1 oil with filter at Autozone or Advance Auto on sale.Is it worth gambling?
