2010 engine break in period?

[rapev-8]

hello everyone, just bought a new 2010 yaris 2 dr hb and my question for today is break in period?
i know alot of cars back in the days you will need to drive under 3500 rpm for 500 miles before you can beat on it :) (kinda like a new clutch put in a car) does it still apply here on my lil car?

[cougar65]

I just babied it for te first 500 then just started driving it like I would any car. It's strange how it's not in writing any break in instructions...

Think it's 1,500 mile break in period stated in manual . I always change oil and filter not long after that .

[rapev-8]

should i change the oil myself or take it to the dealer? cause i got that stupid "toyota care" and thats every 6 months or 5000 miles.

[Hershey]

That's up to you . If you do change the oil and filter make sure to save the receipts and to record the mileage , date , type of oil used ( weight + brand ) in your service manual . The oil change is very easy . I do it myself because I make sure not to overfill , spill oil , and know oil filter is tighened properly . We've had / seen where they forgot to put the oil in , overfill engine up to a quart , and not install oil filter properly so it leaked oil to th point of the engine loosing over 3 quarts . Maybe your experiences have / will be better than ours .

Page 122 in the owner's manual

For the first 200 miles avoid sudden stops

for the first 500 miles do not tow

for the first 1000 miles
do not drive at extremely high speeds (you should never drive extremely high speeds imo)
avoid sudden acceleration
do not drive continuously in the low gears
do not drive at a constant speed for extended periods

unfortunately it doesn't say how long an "extended period" is? an hour? 2 hours?

ok, so maybe 1000 miles before i can beat on it :) yea i never let anyone else do my oil change beside myself, but try doing my IS300 or the 98 4runner v6 could be a b*tch. but i ll be doing the first oil change myself then

yea man not a good idea!

New cars do not require break-in periods. That is 1970's thinking.

[Hershey]

Then why does TOYOTA have a break in period that suggests a certain type of driving in the owners manual ?

i beat the shit out of my car day 3. that's 500 miles in. i got bored babying the new car.

Actually they still do.
Even though modern enging do not require the break in of old,
Engine parts still have to wear in together.

Engine parts also tend to wear in together better if the speed is varied a bit for the first 200 miles or so.

The prime reason why modern engine do not require break ins like in years past is because modern machine tools are much more precise making tolerences tighter. They still need to wear in together though.

I'm not getting into the how long a break in should be argument......I know better

so u go by what toyota says like its the bible but feel they are buffoons?

i was very gentle on my car for the first 3000km and i was told to stay off the highway.

all y'all worried about the break in period should also realize that unless your car had 0 miles on it when you bought it, it's likely been on at least 5 test drives and nearly everyone on a test drive floors it to test the car's pickup.

I nor anyone here can intelligently answer that question. None of us are Toyota engineers. I can tell you this, engines today are built completely different than 40yrs ago. Fuels, oil viscosities are all 100 times better than the 1970's. Most engines today are aluminum as opposed to cast iron. We have fuel injection & ECU's that control everything. Cant compare 1970's to now.

well, the way i look at it. i have the skill and the tools to pull out engines and do my own mechanical work. thank god for warranties. someone once told me a toyota engine is never actually "broken in" until around 100,000 miles
