RossMAN,
Here is the real deal in ref to your ? on the new Honda.
Honda is undoubtedly one of the world's great over-all autos.
1. As previously stated, let it warm up as you drive it away normally. i.e. drive it to warm it.
2. Use the gearing to vary the engine RPMs. i.e do not hold the RPM steady during the break-in period.
3. Follow the factory manual guide-lines on the break-in oil change (probably 3K miles), and always change the filter with an oil change. This is so that the specially formulated oil allows the proper friction to properly mate the contact surfaces (such as rings and cylinder walls, rotating & recriprocating contact points).
4. Even if it says Pennzoil on the hood at Indy, the driver(s) and crew use Valvoline. Use Valvoline in your Honda.
5. Your Honda could be broken-in at 50 miles by following this procedure...
In Third gear (after it is fully warmed up), stand-on the footfeed for a five MPH increment starting at approximately 2,500 RPM. - Then, let-off the footfeed 'till it descends to 2,500 RPM or below.
Do this about Ten times in succession.
After third gear is complete, do the same in Fourth gear, repeating the above procedure, Again, do this 10 times in a row.
The same for Fifth gear...10 Times, a five MPH increment.
Your new car is now totally broken in and you no longer need to pay attention to anything except checking the oil & water.
Following this procedure, I usually put 300K+ miles on an engine without anything except routine maintenance, and don't forget the Valvoline (not Synthetic, also, no need for any of the new "high mileage" oils, it's just a marketing gimmick).
Thanks, and a tip 'o the hat to Jim Buick (and another Jim, a former Dr. of Motors.)
