I run M1 5-20 with M1 oil filter. In the Accord EX. Change the oil every 7500 miles or there about.

Will run the same in the Civic EX. I will do its first change at around 4k miles. I will not let break in oil run 7500 or 10k period. Will get the engine up to running temps. dump the break in oil and filter. Then refill with cheaper oil and a cheaper filter to flush as much crud out as I can. Then bath it in M1 oil and filter.

I will also do a tranny fluid change on the Civic. Did a dump and refill on the Accords tranny also at first oil change.
