Ive always used royal purple race 51 in my motors and 75/w 90 in my drives and napa racing filters. have 400 hrs on my hp500s and still run like new and oil pressures are still as they were new. i change the motor and drive oil every 20 hrs.

I am using Mobil One V-twin 20w-50. So far I am having good
results. Each oil change I send a sample to Blackstone Labs
for analysis. So far virtually no wear on my 496 HOs.

I've used Mobil One 15w-50 in my last three boats with no problems. My engine builder said to use Mobil One (Innovation) so thats what I'm sticking with. Royal Purple is also good. I use their gear oil in my drives (Konrad).
