The only 15W-40 oil I can find says it's for heavy duty diesel engines. If I'm not running my motor is sub 40 degree weather, does it even matter what the winter viscosity is?
My LS3 manual calls for 15W-40. Oil cap says 5W-30.www.1320diesel.com Home of the Fastest Diesels!

Go with 10W-40 if you cant find 15W-40. I think Merc makes a 15W-40 4-stroke.Mikes Liquid Audio: Knowledge Experience Customer Service you can trust-KICKER WetSounds ACME props FlyHigh Custom Ballast Clarion LiquidLumens LEDs Roswell Wave Deflector And More
