So what is high and what is low RPM for this car.</font>
Based on my experience riding motorcycles for the past 30 years, I've found that RPM isn't that critical as long as you're not "loading" the engine too severly. Motorcycles, in general, have higher performance engines than automobiles so break-in is more critical. Most of the bikes I've owned recommended limiting engine rpm to 3000 to 4000 rpm for the first 500 miles or so and then 6000 rpm up to 1000 miles. These are engines that red line at or above 9000 rpm. After that, they pretty much cut you loose to ride like you want. These numbers are probably pretty safe but if you're limiting the engine to 3000 rpm and doing full throttle acceleration at the same time, especially in the higher gears, you're not doing the engine any favors. I found it interesting that the manual in my current motorcycle, a 1998 Honda ST1100, simply recommends, and I quote;
"Help assure your motorcycle's performance and future reliability by paying extra attention to how you ride during the first 300 miles (500 km). During this period, avoid full throttle starts and rapid acceleration."
And that's it! Basically, you can rev it all you want, just avoid full throttle operation and hard acceleration, at least initially. That 300 mile figure is also the shortest I've seen recommended on any motorcycle I've got experience with.
In the case of an automobile with an automatic transmission, the system will shift gears in relation to how hard you're putting your foot in it. I tend to agree with Nemogira, anything under 3000 rpm is probably Ok for the first 500 to 1000 miles. During that time, the occational "brief!" burst of acceleration won't hurt anything. In fact, it may help to seat the piston rings. Beyond that, I don't think I'd worry about it.
The most I remember reading about break-in on any cars I've owned is to simply vary your driving speed for the first XX amoung of miles. Out of curiosity, what does the Odyssey's manual have to say on the subject?
