Thanks for the input guys. As for filters, I was thinking fram tough guard.... jk
Was going to use the my favorite, K&N. Do the first cheapo filter with a Napa gold or something. For oil weight, 5w-30? I have always ran 10w30 in my other vehicles.
I would have run full synthetic in my last car, but the oil pumps in the 1.8L mazda engines dont like synthetic, so i ran semi-synthetic.
