picked up a 2012 exl today

the car salesman said that the car should be not driven at the same rpm for more than 5 minutes during the break in period

see no mention of a break in period (search of pdf owners manual) other than no revving or sudden braking the first 600 miles.

please post your thoughts and experiences

thx

i was wondering the same thing, i read on some blog that with new engines you actually need to go full throttle for the first 20 miles so the combustion pressure would seal the cylinders seals Google it... im at a loss how the manual says just the opposite and he can say what he says...

If you want a new engine at 50 miles go for it. Use your logic, all parts in your car are brand new and need to be worked in gently, especially the engine. It needs to polish itself out, if you go full throttle you may damage your engine or have an excessive oil consumption. When you polish your car do you start with the your polishing machine with full throttle or you gently increase speed as you progress?

....no revving or sudden braking the first 600 miles.
You got it...

Ours had less than 100 miles when we set out for our vacation trip to Charleston, SC via Charlotte, NC. We hit the magic 600-mile mark while in Charleston, and had plenty of "same RPM" travel along the way. The key is to be gentle while the friction surfaces in the engine and on the brake rotors get bedded in.

Your salesman must be "old school"... I haven't heard advice like that since the 1970's ;)

I would follow the written advice of the manufacturer over the spoken word of a salesman.

The "old way" used to guarantee that oil made it to the cylinder walls. By varying the rpms, you vary the vacuum which in turn pulls oil up the walls when the vacuum is high.
As to whether or not it is necessary, all I can say is that we have a 2001 Caravan(we're seriously looking at a new Odyssey) that we broke in the old way and with 174,000 miles on it, it doesn't burn a drop of oil to this day.

I would just follow the manual written from the engineers.

See post #167 of this link: http://www.odyclub.com/forums/54-2011-odyssey/138999-2011-odyssey-reviews-articles-12.html#post698361

Here is a quote: "For example, Honda has developed a technique it calls plateau honing for the cylinder walls of its engines. Rather than a standard single-step machining process with a honing tool — an abrasive that smoothes the cylinder to the required finish — plateau honing uses two stages of grinding to produce a surface that is ultrasmooth yet leaves a pattern of very fine grooves to hold oil."

It's a van, your not going to be racing it I hope. Just drive easy, no sudden bursts of speed, and vary your speed on the highway and you will be fine. Even if you don't do this, you will be fine.

This is really confusing. Brake pad manufacturers have instructions on breaking in pads that includes repeated stops from 60 mph to bed in the pads. How does this correlate with not using the brakes hard? Doesn't make sense. I knew some engine builders when I was younger who used to say to break in an engine by driving in in a normal manner (which by implication meant to vary the engine speed. I think that is legit, but I don't get the don't jump on the brakes part....

Be patient - this engine needs at least 5,000 miles to completely break it in.

In the meantime, check your tire pressure. With the cooler weather, tire pressure drops considerably.

You know I adhere to this idea but take into consideration that all racing engines are new prior to being used and their first couple of seconds of life its being dyno'd at extreme RPM. Race engines are far more sensitive than your average car engine. While I always warm up my engine prior to full throttle usage Its technically its not necessary as long as oil is getting to all components a fuel injected engine needs no warm up.

I dont think race engines were designed to last or even expectected to perform for 5-10 years, as one would expect buying a minivan.
