Going with the Royal Purple
Just bought 17 qts of Royal Purple 15W40 from Napa Auto Parts here in Houston. I decided on RP because that is what we have been running in many of the 500, 600, 700, and 800 rear wheel HP turbo cars we have built and have never had a bearing failure due to heat. We have seen a few because of detonation, but never from burning. RP is the one we prefer, but we have also use Moble 1 with very good results. They are both fine products.
