what kind of oil do YOU use in your boat......

[riverby5]

some swear by synthetic and some swear by the thick shit....whats your choice and why....

[Lightning]

Synthetic thick shit.... Mobil 1 15-50

[voodoomedman]

Torco Racing Oil because Aaron at Absolute puts it in there and says it is the best stuff for it.
In the cars and truck I use Mobil 1

[rivercrazy]

Mobil One V-Twin. The best oil available by far....

[djunkie]

Mercruiser oil. I think its like 25w-40 or something.

[HatenWinter]

Valvoline 20/50 synthetic blend- 496HO

[acatitude]

I use valvoline racing 20-40 non synthetic. I change it evry 20 hrs, cant see the need for synthetic.
the thick shit is hard on your oil pump and bbc dont need 80 90 lbs of pressure. ALso I was told and it made sense, although there are lots of theries out there about straight or multi grade, that since your rpms change so much when boating, low to high and wot runs to idling thru slow zones that a multi grade was actually the better choice. yes i know there are different opinions all probably have some validity

[KROOZIN]

Mobil 1, 15w50 or equivalent

[Sane Asylum]

Amsoil 20-50 severe duty racing oil........496HO's.......Oh chit that's right.. Nevermind...

Amsoil purchases their base stock from Mobil One! And resells their product in on a network marketing basis (Pryamid scheme)!

[BowTie Rick]

Whatever I can get on a comp as long as it is Racing Oil. Racing oil is made for the kind of abuse a boat motor takes.

[BarryMac]

Mobil 1...

[Sigus]

Kendal racing, 525HP
Prior to the 525 I had a 540, before I sold the boat the motor had well over 300 hours, that engine is still in service and giving the new owner a lot of reliable fun.
Change oil every 20 hours.

[cola]

Swepco 50w

The biggest difference in brands is their marketing programs just like bottled water and toilet paper

Mobil 1 v-twin for me. Here's some good reading about different types of oils. They aren't all created equally.

I broke an oil pump while making a 1/4 pass and did not notice no oil pressure till I got back to the ramp and killed the motor, bearings still looked great after tear down
