I was using 1 qt of 15-50 topped off with 10-30 Mobil1, Now the 10-30 isn't available here so I'm gonna run straight 15-50.

Mobil 1 5w30 Ext Perf. Extended performance my ***. Still only good for 4000 miles if you street race your car. Don't forget the qt or qt and 1/2 that you will add before you change the oil. Don't want to run anything else. Going to stick with what came in it from the factory. Although with the oil cooler it now takes 7 qts.
