Of COURSE I'm insane... I own TWO boats and one is a go fast.

Actually both are in theory.. but the Scarab is set up for just runnin not to go fast.

I put VR1 30w in last year, hard to find. Might switch over to 20w-50

I'm not trying to high-jack, or lead this thread down a rocky path, but if the motors are carbed, the issue of fuel dilution comes into play... Hence, Mercury recommends straight weight oil over multi-viscosity. Per everything I've read, the Mercury 20-40 Full synthetic isn't multi-viscosity in the traditional sense of containing viscosity improvers, it's a "blend" of 20w and 40w oils. They also advised against synthetics until they marketed one.
The VR1 advertises high zinc content for flat tappet motors, but since you have roller cams, that is of little benefit to you.

FWIW, I bought the VR1 20-50 for my bikes, not for the boat.

The only reason Mercury calls for a 20-40 ( by memory I believe it's a 25-40) is because there is no such thing marketed by anyone else! Hence, they feel you'll have to buy "their" oil, since no one else carries that blend. And I doubt that they are the "leader" in formulating a synthetic oil, trust me, they're having someone else blend their "Top Secret" blend! Lol

You don't want racing oil. It's only good for one run. Look it up here on OSO.

akaboatman 04-24-2014 11:10 PM

Still can't get any 5 qt jugs of 15w-50 around here. Must be a regional thing.

If any cares 15 w -50 Mystik synthetic blend Super heavy duty engine oil in 8 qt jug (2 gallons jug) for 24.95 at OReilly's till the April 29th. This oil is rated CJ-4, CI-4 PLUS CH-4, CH and SL and you know SL rated means more zinc & phos compared to SM / SN rated. For the money that's a great buy at close to 3 bucks a qt. I think Mystik oil is a Citgo made oil. Anyways just passing that along.
