Hey Guys just purchased my first high performance formula The motor is a 502 w/6-71 blower &daminator carb set up I was told it made 720 HP any suggestions on motor oil??? By the way love the forums I ll probably be on forums more than I'm on the boat

Red Line is great! www.redlineoil.com You can get it through motorstate as well.

There is a looooooong thread on oil, do a search and you'll find it.

I've run:

Mobil 1 15-50
Mobil 1 20-50 V-Twin Motorcycle oil

Amsoil 20-50 Motorcycle oil

No problems on a 540 with a whipple

Thanks guys I thought 20w /50 was it wanted to get your oppion

Sweeeeet boat saxman
