2010 engine break in period?

Add to that the car was driven off the assembly line in Japan into a storage lot.

Then driven/loaded onto a carrier to transport it to a dock.

From there, driven/loaded onto a ship bound for America, etc.

Then driven off the ship to another storage lot, then driven onto a car carrier/train car and transported again.

Then, perhaps another car carrier before it reaches your dealer.

As someone who worked at an auto assembly plant in the past, I can tell you the cars are jockied quickly so......

However, these are only brief perieds and there is no reason to add insult to injury and continue the abuse when you get it as parts are still not broken in and damage can still be done.
Also all this loading/ unloading and test drives are not nearly as bad as someone getting a new car and imeadiately driving it from NY to Flordia (for example) and running it at a constant 3k RPM (for example) before any real break in has occured.

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.

Yes but, piston rings and cylinder walls are still cast iron or cylinder walls are plated with a better weaing metal than what is used for the block.
Even if the block is aluminum, it still has a cast iron/plated cylinder sleeve. Bearing and crankshafts for example are still made basically the same

Basically, the only thing made of aluminum are non wear items and critical bearings/mating surfaces are stiil cast iron or steel.
Aluminum an other alloys are used prmarily just to save weight, not for better wear properties.


Granted, oil is much better but, parts still have to wear in to one extent or another.

Capice?

Why driving at constant 3k RPM is bad? I got my brand new car in GA and drove 5hrs to FL at 3k rpm, did not have any problems...

Go check out the break-in period for a new GT-R. It's like mission impossible.

it's a yaris. a stock one at that. don't rly see the point of beating on it?
