Hello everybody, I'm a new poster here, but I've been reading bitog for a while. I have a question about the use of Royal Purple. I cant seem to find much information in the community about this oil peoples experience with it. I'm trying to figure out how the community feels about it and any experiences with it. My application is a modded Suburu WRX 2.0l, which produces about 300 bhp. I really want to give this high output motor the best chances for longevity at these power levels. And a little history - this is my second motor. The stock motor blew a rod bearing 2000 miles after using Mobil 1 5w30. The car was running stock power at the time. So I will not use that every again in a Subaru. Any other suggestions are welcome. Thanks!
