I have 40 miles on my rebuilt 84 1.6N/A JK motor. I made sure the first 20 miles were broken-in pretty good. I am going to change the oil to shell rotella 30wt and drive as many street miles as possible. I am going to drive the car from Southern California to Northern California in 2 days on Highway 5. How many miles should the motor have before driving on the freeway for 6-7hrs straight? Also, the posted speed limit on the 5 freeway after the grapevine is 70mph if that makes any difference. Thanks!
Wow, it's going to be hard to accumulate 400-500 in 2 days!
