I'm a conventional man myself. For me, putting out 400whp my oil gets dilluted with gas FAR FAR before the oil ever reaches its useable life span in mileage. I change it roughly every 2000kms.

10-30 at the start of the season, 20w50 in the peak of summer, 10w30 in the fall.

IMO, once you get much above stock power and are injecting a little more then stock fuel, your oil will be contaminated very fast. Whether you do $45-50 dollar synthetic chnages, or $15 dino changes the oil gets gassy either way and needs to be changed....so I opt for the cheaper of the two options.

EDIT: its also just carquest brand oil since I deal alot with them. I also use their oil filters which are carquest badged WIX filters.
