Regardless of what engine, lots of benefits seen from switching to Alisyn drive oil. I gained 2 mph on a V6 boat, 454 mag nova gained 4mph.

Re: POLL: which oil do you use ?
My 15-40 Diesel oil experiment has ended,, and I will not be using it any longer in my 496.. going to stick with Castrol syntec synthetic blend 20-50.. After a VERY hard hour long run at lake champlain I found my oil pressure's at idle dropped quite significantly,, seems the lighter weight cannot keep the pressure up when it get hot..

At the TMP shop they use 20-50, and tell all their customers to change every 10 hours. I have a quick oil change set up on the motors so it can be done in 30 minutes from filter to refill, plus it keeps my 1 year warranty in effect, to me oil is cheap insurance.

Just giving up on 15-40,,, it's not enough oil for our motors, after long runs, oil pressure suffers.
Wondering if mobil 1 15-50 will do the same ??
