Break In Period?

gpstrac said:

So I have 300 miles on my IS F now, and have heard different opinions on the proverbial break in period. Can I get some advice on this subject? Is there a break in period, if so how long and what type of driving should I avoid or encourage during this period?

It is completely up to you on whether or not you want to follow the break in period. The manual says the break period is 681 miles and includes no hard acceleration or breaking, no driving at a constant speed for a long period of time (varying your speed), no high speed driving and a few others I believe.

Some people only wait for the 681 miles and then go ball$ to the wall, some don't and pushed the engine hard as they left the dealership, others waited for higher miles before pushing it real hard.

Personally I just drove it like its going to be driven, mostly relaxed driving with a few hard runs here and there and high speeds every once in a while, its completely up to you

Hope this helps

681 is the magic number. I like to round it off to 1,000 just to be safe. Letting the seals seat properly is key. You don't want to clean up an oily gunky mess around your valve cover seals after 30k miles.

Or Do my Crazy method of 5K miles which is around the first oil change..I just went by what the dealer recommended..Worked for me..As I really burn rubber down the highway to the danger zone..

i did 2k miles!, but floored it the first day i got it, just to see how it was lol, so tempting everything just driving the car, but honestly when these cars are built they go through a lot of miles, before they are actually set to 0, because to check the engine to see if there is any problems, obviously they aren't going to sell a car where they just built the engine, and then stick it in the car, and sell it.

Funny you mentioned it. My dealer already sent me a notice for my first 5k oil change, but I barely passed 1200 miles. My car reached the break-in point but definitely not the next oil change...

Come on guys! I just got my 5k service done last night at Longo Lexus. Catch up!!!
