What oil are you running in your boat?
 

After voting, specify brand and viscosity in a post.

Baby oil........or sometimes 3-in-1

Mobil but, Valvoline has a new synthetic oil out that may only be sold at NAPA. Thats the only place Ive seen it anyway. Its called "Not street legal" and comes in a straight 50wt. They claim that it has extra additives that will clog and destroy a catalytic converter hence the name. Its also cheap! Under $3 a quart if I remember correctly.

what ever they have in that bulk bucket. it's the cheapest.

Valvoline VR1 straight 40.

Amsoil 20w-50

AMSOIL 5W-30 in the truck and wifes car. AMSOIL 20W-50 in the Formula, AMSOIL SERIES 2000 Racing Two Stroke Oil in the Skater sleds, weedwacker, chainsaw, leaf blower etc., Amsoil in the Waverunner 1400 4-Stroke and all other miscellaneous items i.e. lawn mower, snow blower etc.

I also run AMSOIL SERIES 2000 Racing Gear Lube in all gear cases, chain cases (sleds), differentials etc.

Redline in everything.

Here's just one reason why

Amsoil 20-50. Series 2000 racing gear oil in outdrive.

Not running a DAMN THING, as the boat and truck are just sitting there waiting for the rain to stop. Mobil1 waiting in EVERYTHING though.
