No Break-in???
Hey guys, I just picked up my Tungston Pearl 350 tonight and before I left the dealership I asked my salesman how long the break-in was, and he responded that there wasn't one... He said the lexus motors don't need a break in. I don't believe him, you guys agree?
Also, as soon as I got home, I looked on my driver's side window and there appears to be a 4" scratch on the bottom of the window. It doesn't look deep, but I don't know if there is something the dealer can do to fix it or if they have to replace the whole window?

grats on you purchase... according to IS350 manual its 1000km no sudden acceleration. for the first 200 miles or so no hard stops. i'm just going by memory since the manual isnt next to me. if im error... i will appologize now. but im pretty sure thats what the manual states...
now all i need to do is figure a way to change my name
I've been reading alot on this very subject and everyone has thier own opinions on how to break it in. Personally i would just stick with the manual.

actually, believe him. there is no official breakin required at all. if you read the manual, it says if you want, you can drive easy on the car and vary the rpm for the first 500 to 1000 miles, but there is no real "rules" you have to follow.
i drive a bit easy for the first 500 miles, but i don't really baby it, i still rev it high sometimes (on my is300 and sc430)

I highly believe break in is crucial. Anywhere from 500 to 1000 miles. I believe in going really easy the first 500, moderate up to 1000, then it's free for all after that. 
I follow this method because it helps allow the seals and gaskets to properly wear in and prevent that dreaded ugly valve cover gasket oil seepage/leakage when you get past 50k miles. I drive high mileage and follow this method everytime. I have yet to have any leaky valve cover gaskets on my vehicles. I have 76k miles on my 27 month old IS300 for reference.

well from what ive seen and read over the years, ive come
to one conclusion, the proper way to break in a car is
not really known by anyone, lol i personally just drive it
normally for the first 500-800 miles, then after that i'd get on
it here and there , until about 1,500 miles.. Just to be safe, i mean
everything needs to be broken in ,somewhat, so why not a engine?

Break in
My salesman, a pretty savvy car guy who does his homework, said he has talked extensively to the Lexus pros in Chicago re: break-in. Their recommendation is to 'run it hard' for the first 1000 miles. Their rationale is that the engine is built to take it and that running hard does the best job at seating the rings. Best for future performance and fuel economy.

I think that guy "motoman" was referring to racing motorcycle engines..
which are meant to be changed frenquently,, Hey just to be safe i drove my
car normally, meaning i rev it to about 4 grand everytime i take off, and i completely
winded it out to about 6 grand in 2nd gear twice, and i have 200 miles so far.. So i guess its better
to just do a little of both because like i said no1 really knows, all engines are built
differently, not drastically different, but different non the less.
