0-200 miles ( 0-325 km ) : Try to keep the highest rpm under 3000 rpm. Every 15-20 miles, zing the engine to 4500 rpm in first and occasionally in second gear.

201-400 miles ( 326-650 km ): Try to keep the revs limited to 3500 rpm. Raise the "zing" rpm to 5500 with the same frequency as above.


401-600 miles ( 651-970 km ) : Go to 4000 rpm for driving limit. Raise the "zing" to 6000 - 6500 rpm and include 3rd gear pulls, same frequency.

600-800 miles ( 971-1290 km ): 4500 rpm driving limit. "Zing" it to 7000+ rpm and include partial 4th gear pulls.

800-1K miles ( 1291-1615 km ) : 5000 rpm limit with "zing" to 7500+ rpm with some pulls all the way through 4th and partial fifth gear pulls.


Now, don't misunderstand me on the zings. You don't HAVE to scream the engine religeously at the prescribed intervals. If you don't have the space to run the engine up in the selected gears, don't do it. Just know that you can, and IF the opportunity comes around lay into it. Don't over-do the procedure.

I recommend that the oil be changed at the 1K mile marker. If the plugs are looking good and if the compression's (and leak down numbers) good, switch to Mobil 1 for life. Use either 0-30, or 10-30.

After the oil change, you might want to reset the valves and from that point on, drive it the way you'd normally run it.
