I've been using German Castrol in my '06 WRX for the past 4.5 years; 2 years in Oklahoma City and 2.5 years in Colorado Springs. I'm moving to the Florida coast in a few weeks and am curious if I should/can stick with GC or if I should switch something else (some have recommended Rotella T6 5W-40). OKC was regularly 90-95 degrees from May-September, and the average high temp where I'm moving is 90 during the summer, 70's during the winter.
1. Should I stick with GC 0W-30 or switch to Rotella T6 5W-40?
2. Can I switch from GC to Rotella without any adverse affects?
Car is not a track car at all, just a daily driver with light mods.
